Router is 802.11B with wireless adaptors. About two months ago Comcast said that wireless had to be set up to obtain an ip address automatically and obtain DNS server automatically and since then I keep loosing my wireless connection. Local DHCP server is enabled and allows connection to TCP 192.168.100 with 50 access addresses. When I loose my signal to the router it says it is aquiring network address and just gets hung up and after about three minutes it says TCP 168.xxx.xx.xx and says limited or no connectivity. System one on the network should be assigned 192.168.100 and number 2 should be 192.168.1.101 which it does when it works. Any ideas on what is wrong? linksys has been worthless. They keep sending me to a downloadable test program that says nothing is wrong and when I do speak to them I cant understand a word they are saying.

Re: Linksys wireless looses connection

I have the same set up.<br /><br />I found the problem to be that my sons laptop would override the Linksys and lose connection.<br /><br />Once I fully "secured" the connection (with Linksys help) I had no more issues with "invading signals".<br /><br />In the meantime, try this. <br /><br />1. Shut down your computers.<br /><br />2. Unplug your Router.<br /><br />3. Unplug your modem.<br /><br />4. Let them sit for about 1/2 hour.<br /><br />5. Reconnect everything in reverse order.<br /><br />6. Assign a new DNS name/connection using the number string that you know works.

Re: Linksys wireless looses connection

OK, lets start by setting up the router.<br />Open web browser and enter 192.168.1.1 on address line.<br />Log into the router <br />Find the menu section showing the settings for DHCP<br />The default range is 192.168.1.100 thru 192.168.1.150<br /><br />Do you have the need for 50 computers to be connected?? If not, reduce the number of available assignable IP's from 50 , down to say 10. This would make your new DHCP range 192.168.1.100 thru 192.168.1.109.<br /><br />BTW, you DID change the default login and password for the router..right?? If not ,do it now, and write it down. <br /><br />If you have WEP enabled, and/or MAC address filtering enabled, disable it for now. After you get things working, you can go back and enable them.<br /><br />For the laptop computer you have 2 options to get an IP address from the router. The first is DHCP, where the router assigns you an IP address. The other option is to statically assign an IP address.<br /><br />Go into Network setting in Control Panel, Network Connections and then properties for TCP/IP for the wireless adaptor. For the first option (DHCP), click on Obtain IP address Automatically. Make Obtain DNS address automatically as well. Make the Gateway IP entry the same IP address of your router (192.168.1.1)<br /><br />If you want to go with the second option, to assign your own static IP address, make that the option by checking the box and then enter your own IP address. Your range will be from 192.168.2 thru 192.168.1.99 OR from 192.168.1.110 thru 192.168.1.254. You may have noticed that I omitted the range of 192,168.1.100 thru 192.168.1.109...thats because we setup your router to use that range for it's automatic DHCP range. Do NOT assign a static IP address that the router is using for it's DHCP, the router gets snakey if you do.<br />Again , make the Gateway entry the IP address of your router (192.168.1.1). Default DNS IP's are automatic..<br /><br />Some folks make the Gateway IP address the same IP as their router (192.168.1.1). They also make both DNS IP's the same as their router as well(instead of automatic). The reasoning is that the router will already have the Comcast DNS routers IP's addresses...Windows TCP/IP doesn't have to look any further that your router for these settings.<br /><br />Personally, I prefer to use static IP addresses for my computers. I know 'where' each machine is in my network (by IP addresses). Knowing where each machine is in my network allows me to open ports and forward ports to specific machines, by their IP addresses for programs like Bittorrent etc.<br /><br />After things are connecting, remember to go back into the router and re-enable the WEP/Mac address filtering etc.<br /><br />Depending on the model number of your router, perhaps there's a firmware flash available to upgrade to WPA encryption...upgrade if it's available...it's better than WEP. If you only have WEP enabled wireless adaptors(that don't have WPA) then this is a mute point...consider replacing them with newer units. ;)

Re: Linksys wireless looses connection

First off thanks for the help and replies. DJ I did as you suggested and it works for awhile then I loose my connection. It is like the router will not allow the computer to use the TCP IP address it is suppose to use.<br /><br />Xcusme. First I have renamed my wireless network and have changed the passwords and am using WPA-PSK and the data encription is set to TKIP. What that means I do not have a clue. I also notice if I disable the SSID broadcast I can not get on my network wireless. I have only two desktops one of which is now hardwired and the other is using a version 4 wireless adaptor. Your instructions do not jive with what I can do with the adaptor. Under wireless connections properties I have two tabs. One is general and the other is alternate configuration. Under the general tab I can either select Obtain an IP address automatically or use the following IP Address. I am currently using the obtain an IP address as per comcasts instructions. Second option under the general tab is obtain DNS server automatically which is what I am doing as per Comcast. If I have that option selected I can not select us the following DNS server address. Those are the only options I have on that tab. There is no option to make the gateway IP entry the same IP address of your router. I originally had the (Damn got disconnected again. When I loose connection it says IP address 169.254.54.47 Subnet mask 255.255.0.0, then Private something. Now it has re hooked up and is working correctly at 192.168.1.100. It tries to hook up to an alternate connection which I have set as automatic private IP address when I set it up as user configured I used 192.168.1.102 and It would not accept the internet however It said I was connected to my router. Any suggestions where I should go now or just blow the damn thing up and go back to dial up.

Re: Linksys wireless looses connection

Back to dialup?? HA! Lay down 'til the feeling goes away...<br /><br />"Under wireless connections properties I have two tabs. One is general and the other is alternate configuration. Under the general tab I can either select Obtain an IP address automatically or use the following IP Address. I am currently using the obtain an IP address as per comcasts instructions."<br /><br />Comcast tells you this if you are not using a router. Since you have a router, it is factory set to already obtain an IP address FROM Comcast automatically. The router gets the DNS IP's from Comcast as well, automatically. These settings are on the WAN side (internet)of your router. Your configuration settings are on the LAN side (your equipment side). <br /><br />Under the General tab, do you have TCP/IP entry in the middle box?? Hi-lite the TCP/IP line and click on properties. In this section you can modify how the IP address is obtained and how the DNS IP addresses are obtained. Also, you can enter the IP address for your Gateway ( router-192.168.1.1)<br /><br />I think I see something else. When you picked your own IP address, you picked 192.168.1.102....As I mentioned in my first reply, "Don't assign yourself an IP address that is within the DHCP range that the routers DHCP is set to.<br /><br />The whole range starts at 192.168.1.1 and goes thru to 192.168.1.254.<br />The router is at 192.168.1.1<br />The routers DHCP range starts at 192.168.1.100 and goes thru 192.168.1.150<br /><br />Use any other IP that is NOT listed above. So, you can use any address between 192.168.1.2 thru 192.168.1.99 OR any IP address between 192.168.1.151 thru 192.168.1.254.<br /><br />If you assign a static IP address that is within the already used IP range of the routers DHCP (which you did), things get very unpredictable.<br /><br />Two more things, What is the model number of your Linksys router and what Make and model number wireless card/adaptor are you using??<br /><br />BTW, the WPA/TKIP is good, just use a password for the encryption that is NOT in the dictionary,the longer the password the better. Use some upper and lowercase characters in there as well. It's called a strong password.

Re: Linksys wireless looses connection

If I choose to use a specific IP address I have to insert IP address, Subnet mask and default gateway. Also by doing this istead of selecting obtain an IP automatically I also can not use obtain a DNS server address automatically. I will also have to enter prefered DNS server address and alternate DNS server address. The old dns numbers I got from Comcast a couple of years ago was 204.127.204.008 and DNS 2 was 216.148.227.204. When I use these DNS numbers with the static address of 192.168.001.002, subnet mask of 255.255.255.0 and default gateway of 192.168.1.1 I can not get on the internet or get into the router. I switched back to auto IP and am able to get back on the internet. My router is Linksys BEFW11S4 version 4 80211b and the adapter is Wusb11 ver 4 adapter.<br /><br />The other thing I dont understand is if I turn my SSID beacon off why I can get on wireless. Seems to me I used to have this off and I was albe to talk to the router. I think the router is FUBAR. Firmware and drivers are all updated and the wireless adaptor is new because the one I had before just quit working completely .

Re: Linksys wireless looses connection

The SSID beacon broadcasts the SSID to the world, turing it off is a must. Since you know your SSID and have added it to the config on you PC adaptor you will be able to connect and do not need to broadcast it! <br /><br />I'm not familar with Lynksys and not sure if this was mentioned or not but .... do you have a cordless phone operating on the same GHz? You could be losing signal strength every time the phone is used? if so change the settings on your router or get a new phone. Not likely but a microwave or other appliances can cause issues.<br /><br />To try and track down the problem you could try turing off all authentication and encryption just to see if it makes a diff. Can you plug in via ethernet directly to the router, try that and see if it drops the connection of the PC connected via wire.<br />My older DLINK had the same issue, it was a firmware issue and was never right. Switched to a new DLINK and a Cisco laptop adaptor and have had zero problems.<br /><br />Did I miss the OS you were using? XP has a few conflicts. Turn off all automatic wireless features in XP.

Re: Linksys wireless looses connection

Running XP with SP2. I have the fire wall for xp disabled and am using mcaffees. I dont see any wireless features on this system. It was a recently converted ME system to XP about 6 months ago. We have 2.4 Gig phones and per the advise of someone here on Iboats I have switched from channel 6 to channel 11 which helped with the hangups we were experiencing a few months ago. I lost the link to both computers about 2 hours ago. One hardwired and the other wireless and had to unplug the modem and the router in order to get back online. May have to use the router for fire work experiments soon and get something more reliable. Maybe go to 5.8 gig. Who knows. I know when I finally destroy or fix this router/ problem I will be a happy man.

Re: Linksys wireless looses connection

Here is some reading that may not help but anyways<br /><br /> http://www.oreillynet.com/pub/a/wireless/2003/09/26/ssid.html <br /> http://www.wilderssecurity.com/archive/index.php/t-85915.html <br /> http://www.nomatica.it/forumthread.asp?code=106750&thread=4 <br /> http://8help.osu.edu/2161.html <br /><br />Since the wired PC is also dropping off indicates it is not a Wireless issue but rather a firmware issue (you say you have the latest and greatest but check again?), modem or firewall problem. Try turning off MaCfee's firewall and see what happens.<br /><br />To make sure (you likely tried this) disconnect the router and go back to the basic DSL modem only set up and see what happens. <br /><br />I like the fireworks idea, get your money back (if you can) and buy a DLINK.

Re: Linksys wireless looses connection

Cant get the money back. I have had this system for 2 years now. I ran linksys system check and I feel much better now that they can not find anything wrong. After spending 3 hours with them on the phone and not understanding the dialect they use I will probably get a different system. I may get the DLINK system you mentioned. The only issue I have not explored is the modem. It is a motorola and I have never updated it and was unaware that it was updatable. I will check into that next. I did try disabling the SSID broad cast and as mentioned before I lost my connection with my wireless and had to re enable it with the hardwired system.

Seems to me I used to have this off and I was albe to talk to the router. I think the router is FUBAR. Firmware and drivers are all updated and the wireless adaptor is new because the one I had before just quit working completely .
When you goto a static IP address, like you did at 192.168.001.002, this is the wrong format for the IP address. It should be 192.168.1.2 (i think you just typed a typo , here in your post) that should be fine. <br /><br />The entire entrys should look like this:<br /><br />IP 192.168.1.2<br />subnet mask 255.255.255.0<br />Gateway 192.168.1.1<br /><br />DNS Primary 192.168.1.1<br />DNS Secondary 192.168.1.1<br /><br />Wait just a minute, How can the DNS entries be the same as your router IP? It's because the router already gets the CURRENT LIVE Comcast DNS IP's. You can log into the router and goto the first screen showing the status of your connection, you'll see the current DNS IP's that Comcast is using. If Comcast changes their DNS server IP's , the router gets those new IP's. So by entering the Primary and Secondary DNS entries to 192.168.1.1, you're telling Windows to ask the router what the current DNS IP's to use and everything is found. It's a small wonder that you got an IP address from you router but were unable to surf because you were using old DNS IP's from long ago.<br /><br />Now, about your router. That is an older router. Linksys does have firmware for it. You mention that it's a version 4 router, but didn't mention the firmware revision . This can be found in the router settings. Compare the version of firmware to the info on this Link <br /><br />I have to agree with Tedder, if you're getting dropped connections on a hardline Cat5 cable, then it's a router issue. BTW, if you've ever flashed your router's firmware, you must do a hard router reset AFTER the flash for it to fully be implimented.This means holding down the reset button on the router to set it back to factory settings. This means that you'll have to enter any info back into the router (wireless settings etc) manually. Despite what you may have heard, don't try to restore a previous firmwares backup file to the new firmware flash. The eerom gets hosed.<br /><br />As for the interference from cordless phones and microwave ovens,yes it can happen. Since most routers come factory delivered on channel 6, you'd want to change the default channel from 6 to say channel 1 or channel 11. For no other reason than to get off the channel all of your neighbors are using, because most folks just leave it at channel 6 but to also get away from possible cordless phone interference.<br /><br />I agree, you should be able to connect to your router with the SSID beacon disabled, as long as both the wireless adaptor and router have the same Wireless Network Name. The only problem that some have run into is in the case of multiple Wireless Access Points and are roaming betweem them. It might take a bit longer to associate if the SSID is disabled.<br />By having it disabled, other WinXP users won't be able to 'see' your router and ask them if they want to connect to you. <br />Personally it is of little real security.Anyone who knows their stuff can use a program to sniff out your SSID , even if you have it hidden. It take 5 seconds go get ypour SSID.<br /><br />Since you have WPA/TKIP enabled, why care if they can see you, they can't associate with your router if they tried. Having the beacon turned off can only slow down your assiciation with your own router.<br /><br />OK, you said "I dont see any wireless features on this system." Just because you don't see them, doesn't mean they aren't there. I you go into Control Panel, Administrative Tools, Services, look down the list for Wireless Zero Configuration.If it'senabled then Windows handles your wireless connection. You can disable the service, just right click on this entry and hit Stop (to stop it from running) and ckick on Disable then Apply. It won't take over your wireless connection upon next bootup. Now you can use the wireless Client Manager that came with your Wireless adaptor to control the settings. All of this assumes that you have SP2 (Service Pack 2) for WinXP.<br /><br />I personally don't care for Windows controlling something that I can do myself and have more control over, but this a personal preference.<br /><br />If you do go for a newer router, I'd opt for the 802.11G flavor. Awhile back,the WRT54G series made a big splash.It had (has) a Linux OS. Lots of folks modified the firmware and made a 60 dollar router into a 200.00 VPN router with just a firmware flash. I have 2 WRT's myself running modified firmware and are absolutely rock solid. Linksys didn't like people modifying their routers and changed the chipset to one that runs a locked OS...hence , no modifications. You can read more about this stuff by Googleing WRT54 HACK.<br /><br />BTW,there were some issues with some model routers with over heating. Make sure the router has plenty of airflow around it, nothing sittingontop of the router. There's a link to a website that shows you how to open the case of your router (it's like a Chinese(sp) Box. Easy if you know how. The site has pictures of the steps (it's easy...I've done it many times). Anyway, by opening the case, you allow more air to circulate and keep the IC's cooler...less heat, no lockups.... Some folks aim a small fan directly at the router and the lockups stop.

Sorry to jump back in here but I too have my original Motorola Surfboard modem. They did firmware upgrades awhile back and it gave me fits too. To solve the problem. I unplugged my modem for 1 hour (this released my Comcast DHCP issued IP address) When I powered back up, using a paperclip, I held in the reset on the back of the modem. The newer firmware was then loaded and it's been solid ever since, but it took this hard reset to kick it in the pants. ;)

Re: Linksys wireless looses connection

Quoted from Xcusme<br />The entire entrys should look like this:<br /><br />IP 192.168.1.2<br />subnet mask 255.255.255.0<br />Gateway 192.168.1.1<br /><br />DNS Primary 192.168.1.1<br />DNS Secondary 192.168.1.1<br />
When I do this I get prompted that that alternate DNS server can not be the same as the prefered DNS server. Please select a different IP address for the alternate DNS server. I switched the alternate address to 204.127.204.8 and it seems to be working at least for now. I will try the hard shut down on the modem tonight after everyone else goes to sleep. Dont I then need Comcast to reset this after I do it? Seems to me when we moved last year and when I had the original install done they had to do something to the modem both times or it would not work.<br /><br />Firmware is current at 1.52.02. I did a complete router reset last week when I tried to fix the problems from this post. I then re set up network name and password and switched from WEP to WPA encryiption.

Re: Linksys wireless looses connection

Duuh, Sorry , my mistake. Sometimes the differences between Win2K and WinXP blur a bit. Enter 192.168.1.1 for the primary DNS and leave the secondary DNS blank.<br />In Win2K they can both be the same IP.....<br /><br /><br />You shouldn't need Comcast to do anything if you do a hard reset. The modem will take care of the reconnect..<br /><br />One thought, when you loose connectivity, are all the modem lights lit?? Just trying to see if you're loosing BlocSync at the modem. Any changes to your cabling?? Any splitters on the line to the modem?<br /><br />Are both your systems converted/upgraded from Windows ME?? I personally prefer to do a clean install between major OS revisions. Too much can get lost in the translation, but thats just me.

Re: Linksys wireless looses connection

Static IP seems to be more stable then DHCP however the computer still lost connection to the router while the hard wired one still was running. Modem shows 4 lights however we are having problems with our local cable (double image and crap for reception) and I am going to have them out here for that. I have had a couple of times I lost the modem (less then 4 lights) however I can still talk to the router. I put an old dns address in as the secondary and will remove that. Just want to thank you guys for the help.

Re: Linksys wireless looses connection

Strange...I looked up your router and USB adaptor. Seems your router allows WEP or WPA, but i can't find any info regarding WPA for the USB adaptor...only WEP.<br /><br />You said you changed the router from WEP to WPA and added a passphrase....<br /><br />Did you change the USB adaptor to WPA too and use the same passphrase? The version 4 USB adaptor you have mentions only WEP. Could Linksys website have only older docs??

Re: Linksys wireless looses connection

I had problems during the install of the adaptor on this computer. When I put the disc in it just flashed and never did show the install. When I tried to open the application using run N:setup I got a prompt asking me to fix or reinstall the lan monitor. I currently do not have a lan monitor like I did when I had ME. Might be windows is doing the connection instead of linksys. If I go under properties on the wireless connection I have three tabs. general, wireless networks and advanced. Under the wireless network tab I click on my network name and click on properties and I have three more tabs Association, Authentication and connection. This shows my network name and under it it gives me the option for network authentication with choices of WPA-PSK, WPA, open or shared. Then data encryption options of TKIP or AES then network key. My guess is this is XP stuff instead of Linksys because it is does not have any Linksys markings anywhere. Since I switched to XP I have not been able to run a lan monitor on this computer or on my other newer XP machine. When I go to programs, instant wireless, lan monitor I get an error that says c programfiles wusb11wlanmonitor\wlanini can not be found.

Re: Linksys wireless looses connection

Ok, so you have the XP WPA supplicant that allows WPA. This with the Windows Wireless Zero Configuration service I spoke about ealier. There is a selection box that allows you to allow or not allowing Windows to manage your wireless connection. If you disable the Windows control of the adaptor, then you can use the Linksys client manager to manage your connection to the router. Of course the client manager has to be installed. Not sure if you tried leaving everything as is and disabling WPA/WEP altogether as a test to see if it clears the dropping issue. Just something to consider.

Re: Linksys wireless looses connection

I can not get the linksys lan monitor to work or show up. When I click it in the programs file nothing shows up. I will have to go through linksys and find out why I am having this problem. I currently have to use the windows wireless Zero Configuration service until I can get the lan monitor to work. I am not real crazy about dropping the WPA or WEP for a couple of days to try out different things. I need to get comcast out here to fix the local channel stuff which could be causing interference on the internet stuff and I need to get linksys to help with the lan monitor so I can disable the wireless zero configuration stuff. As Arnold Schwartzenager said in Terminator. "Ill Be Back"
