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?

Sorry for all the questions.

 

I'm not sure about the driver side of things, I too am running Windows 7 and had the Intel 5100 card in it working without issue.

The card is definately removable, it's under the hard drive. Problem is HP lock the BIOS to only allow a few makes and models of card. I have recently (for playing around with MAC OSX) swapped the card out for a Broadcom 4321 mini PCI-Express card and it's working perfectly.

The 40ghz doesn't sound right to me but someone may correct me on that but from what I know of the 802.11 standards are 802.11g supports 2.4GHZ, 802.11A supports 5GHZ and 802.11N supports both frequencies but most routers that support 802.11N seem to only be 2.4GHZ.

Hope that helps.

 

Thanks for the info!

Sorry for my ignorance, but then you are saying I could get the card you mentioned and put it inthat slot that isn't being used by anything?

And then I open and remove the 5100 card from within my machine?

I have a DLink DIR-655 and it has worked great but I might upgrade to some 710 model I hear about that is draft 2 I think and some other stuff.

But to really leverage it, I would need to get a bettwe wireless card, although right now I just want it working period.

I've read a bunch of other threads with 5100 and Windows 7 issues potentially as I didn't have this in Vista.

And yeah, I've tried every driver permutation, removing, reinstalling, changing this and that.

Fact is it didn't happen in Vista (which is a shock) and my desktop is perfect.

Anywhere I can look up what cards will work with the BIOS so I can order one from Frys or New Egg?

Thanks!

 

You would be replacing the Intel 5100 card with the Broadcom card.

I purchased mine on ebay from Hong-Kong and it was fine:

http://cgi.ebay.com.au/Broadcom-432...X&its=C%2BS&itu=SI%2BUA%2BLM%2BLA&otn=5&ps=63

That's what you are after, hopefully that will help you search for one if you don't want to use ebay.

 

do you mean 40 as the channel?

there are no routers that transfer at 40ghz
