Atheros to Intel WiFi card - now Bluetooth is spotty

A few days ago I swapped out the Atheros WiFi/Bluetooth card in my ASUS G74S for an Intel Celeron 6320 802.11n/Bluetooth 3.0 card. The increase in WiFi signal strength (which I bought it for) is very good and my connection here is much more reliable, but now the Bluetooth is behaving very weird with my MS Presenter 8000 mouse. More often than not, it takes a long time for my laptop to discover the mouse when it's searching for Bluetooth hardware. This wouldn't be an issue at all, except every time I shut down or reboot my machine, it completely "unmates" itself to the mouse. It'll show the mouse still present (and connected!) in the Bluetooth devices list after bootup, but it will not respond to any signal from the mouse. I have to remove the device, go through a whole new "find" process with the mouse in discoverable mode, and reconnect the mouse from scratch. The weird thing is that if I leave the machine on and shut off the mouse itself, everything works as it should when I turn the mouse back on. This has led me to believe that the issue is somehow stemming from Intel's Bluetooth controller. Has anyone had a problem like this before with the 6320 card? I'm in the dark for figuring it out.

Also, in case it makes any difference, I installed all Intel's latest drivers for the card before physically installing it, made sure the Atheros card was completely removed from Device Manager, and I'm also using Win7 64bit.

Any thoughts?

 

Did you uninstall the Atheros wifi driver from Control Panel? Also, did you uninstall any previous bluetooth driver as well?

 

I deleted that and the Bluetooth stuff from Device Manager just before shutting down to pull the Atheros card out. I wouldn't have expected the drivers themselves would cause a conflict (if that's the case) in the system, as long as it's not specifically looking for a card that's not there.

I could remove the Intel card, completely remove all the Intel, Atheros and all Bluetooth drivers, then reinstall just Intel's stuff from scratch and reinstall the card. What's the best way to ensure they're all completely removed under Win7 though? I'm still used to XP so I'm still in the learning curve.

 

Remove all wireless and bluetooth drivers you have, then start by re-installing the Intel ones. Usually, you connect the device before installing it's drivers.

 

I was about to follow Tijo's advice and reinstall the Intel card and all its drivers from scratch, but when I went into the "remove programs" area (wanting to remove a couple games) I saw an Atheros Bluetooth program in there that I didn't remember seeing before. I easily could've overlooked it before, but either way, I removed it, rebooted, and now my Bluetooth works the way it should. I can boot up my laptop now, and all I've got to do is switch the mouse on and I'm good to go. No more having to reconnect it every time. Chalk it all up to an error on my part.

 

I am curious what was that intel wifi bluetooth card did you get?

 

Bluetooth is integrated into the Intel 6230 wireless card.

 

Isn't it the 6230? Anyways, yeah the bluetooth is integrated.
