Changed wireless card and now Thinkvantage Access Connections is malfunctioning

I decided to replace the Intel 2100 802.11B mini-PCI card in my R40 with a 2200 802.11B/G card (faster, more reliable drivers). No problems installing the thing, booted up the machine and and installed the drivers and connected to my network fine. However, the Fn+F5 key combination no longer works, and Thinkvantage Access Connections can see the adapter but can't do anything else (Windows seems to be handling everything). Pressing the wireless radio on/off button in Access connections doesn't actually do anything for the power status.

More relevant info: machine is running XP Pro and the latest wireless drivers and latest version of Access Connections.

 

I'm having problems too, although not the same issues as you. Just suddenly the other day my system started getting really laggy and I started having network issues. I thought it was due to some new hardware I had purchased for the network, so I spent hours trying to troubleshoot it. I just happened to check out the task manager and noticed TAC running at the top of the heap. With a fresh reboot it was running using about 160MB of my 3GB of memory (which I think is excessive). But occasionally I would check and it would be using between 1 and 2 GB! After watching it just grow until it had tied up 2 GB I finally just decided to uninstall it, considering Vista's network connections are running anyway. It appears that the TAC has a bug which causes one hell of a memory hole, and I'm not sure about what triggers the event.

Checking through my system I think it updated TAC a few days earlier, along about the time I started having problems (I think it was on 4/24). I would have gone back to a backup, but I'm planning on doing a clean install just as soon as I can obtain a copy of that Vista upgrade anytime disk.

 

Thinkvantage Access Connections isn't great to be sure, but I do like having the signal strenght icon on my task bar. That and the ability to turn the card on and off with Fn+F5 is the only reason to have Access Connections installed.

 

You don't need Access Connections to have the Fn+F5 wireless menu. I didn't install Access Connections at all and I'm able to pull that menu up and enable/disable my WiFi and Bluetooth.

 

Good to know that it isn't required for Fn+F5. The key combination doesn't work either after upgrading the WLAN card. Is there any way to make it recognize the 2200BG? The IBM software sees that it's there, it just can't control it.
