Just installed W7 because W8 kept disconnecting my network card (TP-LINK TL-WN851N). And now W7 doesn't even recognise the card. I have already tried installing the drivers but it just doesn't cut it.
Anyone have any idea on a fix for this? BTW Ethernet works fine.

Well if you don't have ALL the drivers installed (not the USB 3.0 is missing) then it isn't going to 'see' anything plugged in.

So let's do the basics here
1) Is this a OEM computer or self built?
2) Did you run ALL Windows Updates, including OPTIONAL, except BING
3) download and run SlimDrivers to install all the drivers necessary. You do NOT need to reboot each time, you can do the reboot AFTER installing ALL the patches

Windows 8 would NOT be a reason a Wifi card 'disconnects'. It is normally other reasons, such as
1) other wifi are close enough (you see them on your 'list' to Connect To) they are 'interfering' with the Wifi Signal
2) your router your connecting to may be using a 'lower' connection (802.11g) instead of the a newer connection (802.11n)
3) your router is old and is just overwhelmed by 'all the things' connecting to it (laptop, Kindle, iPhone, Xbox)
Etc. off the top of the head.

Several other people had reporting the same issues I had with it running with Windows 8. I could be playing a game and suddenly it would freeze for 10-15 seconds and then it would reconnect. My router definitely isn't the problem as I haven't had issues with the previous network device I used (usb wireless thing).

So NO - it does not have "Windows 8" drivers so it wouldn't work properly. Your SIMPLER answer would have been to simply BUY a different Wifi that was Win8 compatible (as you mentioned you tried a USB one), but now your going to have to go through ALOT of hurdles to make this computer and its parts 'work' for Windows 7, which is questionable.

1. Yes it is self built
2. All updates are installed http://puu.sh/c0N6S/8a1987e169.png
3. Will try this.

The funny thing is that it worked on W8 almost instantly, but refuses to work on W7. I didn't look close enough when I ordered it so that's my fault.

EDIT: SlimDrivers installed the network controller driver from Atheros and worked instantly without rebooting :)

NVIDIA drivers has nothing to with the network driver. It fails because I already updated it myself.
