If you happen to own a older D-Link router, this might be relevant:
I've had the disconnect issue with a T400s (using the Realtek wireless LAN min-PCIe adapter II)-- oddly enough, the most frequent bouts of disconnects happened when I was within 10 feet of the router. At the other end of the house, I hadd disconnects from time to time, but not as often. But it was so frequent where I usuallly used the computer that it was a huge problem.
I finally fixed it (based on 2 disconnect-free days, a record) by going into the settings of my router (a D-Link DI 624) and changing the wireless mode from "Super G with dynamic Turbo" to "G only". Apparently Super G (a common feature of D-Link routers prior to the latest N-draft generation) is a mode that provided extra speed with D-Link proprietary adapters, and supposedly was backwards compatible with standard G mode (and, based on my experience with *other* brands of b/g/n adapters, it was. I haven't used a D-Link adapter in quite a while and had forgotten it was on). However it definitely doesn't play nice with the Thinkpad's mini-PCIe adapter II, at least at close range.

If I use WEP, I don't think I suffer any disconnections. But I'm stuck at 54Mbps, which is unusable, especially when watching videos. I can manage 300Mbps using WPA2 (AES), but I get constant disconnections. Maybe my wife will let me delete the Lenovo software and just use the standard Vista software.

I have a brand new T400 with Intel 5100, a Linksys WRT54G router. I am not using Access Connections. Windows XP. Wireless disconnects and reconnects intermittently, and is very slow all the time (actually, long pauses of no data followed by reasonably fast bursts). I have modified all the power settings for the 5100 so it is at max power and no sleep. Using WPA2.
I think the card is the problem, if I connect via ethernet cable to the router, everything blazes along with no problems.
Any solutions? Any suggestions for an alternate card to the Intel 5100?

I installed the latest drivers from Intel (13.x?) and things seem ok. No disconnections for a few hours. Who knows what'll happen after a reboot.
