For the life of me, I can't get my work laptop (brand new ThinkPad T42 with built-in Intel wireless adapter, running XP) to connect to my home Netgear MR314 access point with 128 bit WEP turned on. I also have MAC address filtering turned on.
If I disable WEP, I can get it to connect. But if I leave WEP activated, I can't. The MAC address filtering doesn't seem to make a difference. I've tried setting up 64 bit WEP instead and that didn't seem to help.
I'd rather not disable WEP, and I'd rather not downgrade to 64 bit.
The infuriating thing is that I went through this situation a few weeks ago, which was the first time I brought home the work laptop. When I first tried it, I couldn't get it to connect. I tried all combinations of turning WEP on and off, changing it from 128 bit to 64 bit and back, turning on the MAC address filtering and turning it off, power cycling the router, etc. -- I tried a million combinations and finally, in desperation, I rebooted one more time and miraculously, it worked (with 128 bit WEP and MAC address filtering ENABLED). I had tried so many things that I wasn't sure what worked, but at that point the work laptop was able to connect no matter how many times I rebooted it. I had no further problems for the rest of the weekend (well, aside from the fact that I was *working* the whole weekend).
Since I had the correct settings (WEP key, SSID, etc.) stored in XP (my network was listed as the only "preferred" network), I figured that next time I brought it home, it would already have the settings and would just see my network.
No dice. I've spent the evening trying all these things again (turning various settings on and off, power cycling the laptop, router, etc.) with no luck.
Any ideas? Suggestions? Troubleshooting steps or diagnostic utilities? I'm stumped and frustrated.
