Hi. I happened upon this site from a google search where people were having similar problems to me - but none exact.

I hope you can help (and I hope I put this in the right forum).

Here's the deal - I have SBCYahoo DSL and recently moved to a house with only 2 phone jacks. so I decided to get a wireless network card for my desktop, to use with my existing (and working) Linksys BEFSX41 Router and Wireless access point. I should add that I have always been using a wireless laptop and a wired desktop - both of which worked great.

Since I installed the wireless card, and upgraded the firmware on both the router and access point, I can surf some sites but not others. For example, I can get to fourms (like this one) and google, but not cnn.com or hotmail.

After I did some research, I thought it was an MTU issue. So I figured out what it should be and I enabled it on the router. That didn't help.

If I connect using the sbc software, I have no issues at all - except of course the one of not being behind the firewall.

any ideas??

THANKS!

Try doing a "ping cnn.com" from a command prompt. You won't be able to actually ping it, but it should return the IP address of cnn.com on the first line of results. If it doesn't, then you are having a dns problem. Try checking your dns settings on the router and on your PC.

it does return the ip address but the request times out....

That is really quite strange. cnn.com will never return the ping because they have their firewall set to not reply, but the fact that it returns the IP address implies that you have both DNS and connectivity to the Internet working. If they have software running on your machine that allows you to connect, that is something I haven't seen. What you might try, is with your machine connected directly, do an "ipconfig /all" command from the command prompt and see that the settings it returns are the same as what you have configured on your router. Also, from a command prompt, try doing a telnet "ipaddress returned from the ping command" 80 command and see if you get a connection. You won't get anything but a blank window if it succeeds, you'll get an error if it fails. It should look like this "telnet 192.168.0.10 80" remove the quotes and substitute the correct iP address. Is there any type of access restriction software running on that router? Like parental controls? Just a thought since you say you upgraded the firmware, maybe it's acting screwy.

you hit the nail on the head. I rolled back the firmware and that fixed the problem. Linksys stresses me out :)

Glad you got it fixed! :D Firmware updates? ...as the saying goes, "If it ain't broke....."

I usually go with that motto but I was having other problems with my router so I thought the upgrade would help.

GUESS NOT! :)
