Hi all,
I just upgraded my Acer Aspire One AO722 from a Broadcom 802.11n mini-PCIe card to an Intel 7260.HMWWB card to enable connection on 802.11ac to my router. However whilst the Bluetooth is working fine, the wifi doesn't work at all and comes up saying no connections available. If I run the manual diagnostic program it fails the hardware test with an error of "Wireless Hardware is not bound to transport driver".
This is using the most recent ProSet driver/program package I could find on the Intel website (17.0.5) under Windows 7 home premium 64-bit. I did try the auto-detect and update option on the website, but it either just corrupted the screen and locked the machine up (when run under Chrome) or blue-screened it (when run under IE). Presumably this is due to it having an AMD C-50 processor rather than an Intel one.
Device manager doesn't have any !'s in it, and the Network Adapters section lists "Intel(R) Dual Band Wireless-AC 7260" and the driver tab under it says 17.0.5.8 and that everything is working correctly. I already tried resetting the Winsock and TCP/IP stacks after seeing that tip on various web pages, but that didn't help either.
Is this going to be a hardware issue with the card itself, or is it a general incompatibility between the Intel PCIe card and the AMD-based processor/motherboard? My only remaining plan is to try it under a Linux Live-CD to see if that sees the thing ok or not (as a hardware test), but can anyone recommend any other methods to get this thing working?
Editted to add - Under an Ubuntu 14.04 live-CD the card works fine and plays nice (I'm posting this from it via my 5GHz network) so there's definitely something messed up with either the Windows driver or how they're interacting with my Windows 7 installation. So now the question is what to do to get the thing also working under Windows 7?
