T400 Intel 5100 AGN help!

2009-11-09, 8:59 AM



I recently installed Windows 7 and I have been experiencing slow internet speed ever since.  I have already updated the drivers for both network adapters (Intel Wifi Link 5100 AGN ver 12.4 1.4 and the Intenl 82567LF Gigabet Network Connection ver  I used to be able to recieve 6mb/s for downloads, but now it has been reduced to less than 1 mb/s.


Here is my speed test:






Are there other drivers or software that I need to update to get my speed back?

Probably completely unrelated but maybe not...


I just put a test install of Win 7 Pro 64 on my T400 w/Intel 5100.  It was running Vista Biz 64 and working fine with my Linksys N router.  With '7 it wouldn't see the router most of the time, would occasionally see it and associate sometimes, and always drop in a few seconds.


The "fix" was to enable QoS in the router.  Absolutely no idea why.
