HP/Compaq :: Is The Intel Wireless 5100 (AGN?) Card Removable Or

The DV5T seemed to be working pretty well for me and no real wireless issues.

What has happened is that since I upgraded to Windows 7 and the new drivers, I get some hitching, rubberbanding in games, slow speeds at times, etc.

Now I know Windows 7 is pretty rock solid and the new drivers came from the HP site.

But when I started googling, seems TONS of people have issues with the 5100 card and maybe I was just lucky before.

At first I noticed my card speed goes from ~50 MBPS to max of 130 MBPS. After reading, it seems even though my router supports 40ghz dual channel yadda yadda, the card only goes to 2.4 so it can't really run at 40ghz is my understanding and that 130 MBPS is pretty much the cap.

That said, it was that way before the Win 7 upgrade so that shouldn't change anything.

One thing I noticed is that in my device driver before the upgrade, it was a normal 5100 but now with the drivers, I see a 5100 AGN.

I can't find how the AGN and non-AGN versions differ?

Could it be I have AGN drivers for a non-AGN card?

Lastly, is this wireless card removable and upgradable or can I use the slot (empty) that I have for another card and disable the wireless 5100 through BIOS?
