"Wi-Fi" doesn't have a valid Ip configuration

I've been having issues with wifi on my desktop for nearly 2 months now (by issue, I mean I haven't had any working wifi). The current issue is that there's apparently no IP configuration (the issues are ever changing). I'm on Windows 10, and have two different wireless network adapters (a belkin play N600 and a TP link one, not sure on their exact names) installed. The belkin one originally worked, and the TP Link one I purchased thinking that the wireless adapter was the issue. I also have access to IPv4 and IPv6 (not sure if that's relevant, most of the thread I've looked at only speak of IPv4.) I have tried so many different fixes now I thought I might as well post my own thread in the hope that someone can finally help get this issue fixed!

The first step in addressing WiFi problems is to update the hardware driver. Download the latest driver from the hardware manufacturer's web site. Don't rely on Windows update to get the right one, as that may be the cause of the problem in the first place. Uninstall any wifi devices from Windows then install the new driver before inserting the adapter. While you’re at it, make sure your router firmware is up to date.

Thanks for the response! Unfortunately I've tried that before and cannot attempt it right now as I don't currently have a memory stick... Both of the network adapters I use don't currently have any drivers for Windows 10 as it is, so I installed the Windows 8 ones at that time.
How do I update the router?

The router is likely not the problem, but just a good step to take when working on the system. The firmware update is found by logging into the routers setup pages. Beyond that the it varies according to brand and model.

An expedient method would be to buy an inexpensive new adapter that has a win 10 driver available along with a small thumb drive. Or just plug into the network with an Ethernet cable

Another way would be to try a windows rollback to a time before the problem occurred. I can't help with this on win 10 as I've only done it once to resolve a wifi problem on a friends computer and don't remember the procedure. But its there somewhere.

Okay I'll take a look.

I bought the TP Link (it's model number is TL-WN823N) one in the hopes it would work for windows 10 (I read quite a few reviews beforehand, and it was advertised to work for Windows 10), but it only has a limited connection like my Belkin one which was the one which originally had a connection and then didn't.

I rolled back to the last known working date (I think it was October 24th?) and I still had nothing.
