X61s- Unexplainable halving of speeds

[bugmn]

I'm having a really weird issue with my wireless. Somewhere around the time when I switched from Win 7 to XP, my laptop wireless speed dropped by 60% from 10Mb/s to 4Mb/s.

My other laptop is still doing 10Mb/s so it's not a network issue. And also it isn't a virus or anything and hardware Ethernet is doing 10Mb/s.

I thought maybe it's a power saving issue so I turned off all Wireless power saving features within the drivers (BIOS doesn't have any WiFi power savings), and still the same result.

I'm up to date with all the latest drivers, including WiFi (which is an Intel 4965AGN). Just tried uninstalling and reinstalling just to be sure.

I've tried everything I can think of. I know for a fact I had gotten 10Mb/s in the past on this laptop. Maybe the WiFi is dying? But it doesn't explain why I have 5 bars signal strength constantly and the speed doesn't fluctuate or anything and no drop outs...

Really don't understand. Anyone have ANY ideas?

You might want to disable Access Connections and use the Windows wireless utility to see if that helps. If you're running any encryption on your network or a firewall, shut those down and test it. They may be a source of the isse.

Try a Linux disc and see what kind of performance you get. If it works normally, then it's probably a software issue on the Windows side. If not, then perhaps the card is going.
