Intel Pro Wireless 2200BG problem or Linksys BEFW11S4 problem?

goinglocal on Oct 15, 2007

" "

Hi,

I have an IBM T42 with the Intel Pro Wireless 2200BG wireless adapter. I am having problems connecting to my wireless Linksys router. The router has the latest firmware. The wireless adapter has the latest driver. My OS is Windows XP SP2.

The weird thing is that I use to be able to connect to this router but not anymore (and nothing was changed). I still can connect to my wireless network at work with my T42 and also other wireless networks such as at a hotel or airport. I know the router is configured correctly because my wife's laptop can still connect to the Linksys router without any problems and nothing was changed on her machine.

I've checked the WEP key, deleted and re-added the profile/network, tried different channels, tried different WEP key index, rolled back drivers, and even did a complete reset of the router and my cable modem.

I'm not sure what else to try next. Any sugggestions would be greatly appreciated.

- Sorry, I forgot to mention that I have a linksys BEFW11S4. I don't think WPA is an option? I could be wrong, I'm not really router-saavy!

- Yes, I have the same problem with Intel Pro 2200BG on my T42, after windows reinstallation. I have Linksys as well. I have another T41 at home and it works fine. I swapped the network cards between the 2 laptop, this T42 laptop still does not work.
Both laptops can work if I open the AP, without any encryption.
I used another access router, from D-Link. Both laptops work fine.

That's the reason why I sent the laptop back to IBM but they could not find the reason. The laptop just returned to me as-is- Guest

- I am having just about the identical problem. Did anyone ever come up with a solution to this problem? Thanks.- Guest

I had the same problem. If you are using the latest driver for your intel 2200BG (9.0.4.7). Try to roll back to a previous version. It solved my problems with being unable to connect to a Linksys BEFW11 router running WEP64.

I am now running driver version 9.0.1.9

I am having a similar problem. It all started when I upgraded my Microsoft Office 97 to 2003. It asked me if I wanted to delete some files that might be associated with other applications. I said go ahead, and it did. Since then, I have not been able to connect to the internet. I have a Dell Inspiron 6000 with an intel Pro Wireless 2000BG. I installed the latest intel driver but no cigar. At moment my computer says it cant find MAPI32.dll what ever that means
