Bounty: 100

All devices I have tried (a laptop, all smartphones, a PlayStation) with my WiFi networks work perfectly. The only problem is my desktop PC.

Adapter No. 1

Sometimes the adapter wouldn’t even find any network (and there are lots of them as I live in a building).

When it did find the signal from my network, it was usually above 80%, so that’s not the problem. Connection was very unstable, I usually got only local access with the classic yellow admiration sign over the signal bars.

I’m on Windows 7 and my WiFi adapter was a TP-LINK TL-WN751ND (PCI).

Things I’ve tried:

  • Uninstall and reinstall drivers. This fixed the problem for a while, but after some days the exact same problem started again.

  • Disable and then enable the device. This didn’t change anything, the problem went on.

  • Reset TCP/IP settings. This didn’t work either.

Adapter No. 2

So I thought that the problem would be the network adapter. I bought a new one: TP-Link Wireless USB Adapter TL-WN823N. This one works, but 5 or 6 times a day it just doesn’t detect any network, and a reset is needed for it to start working again. The usual procedure is the following:

  1. WiFi works ok.
  2. Suddenly, it stops working. The image says “Not connected. No connections available.

  3. If I click on Solve problems, Windows solves the issue straightaway. The picture says that a problem with the wireless adapter was detected, and it was corrected by restoring the adapter.

Current issue

I would like to make the second adapter to work. I mean, I can get it to work every time, but it’s very annoying to do these steps all the time, and being affraid of connection being lost randomly at any moment. Is there any way to fix this permanently?
