Internet is working fine, still only 4 bars...happened a few days ago.
The game (warthunder) was fine two days ago, now my ping has shot through the roof...and windows still gives me the proxy error message.
So I'm rolling along the internet and I start noticing that the wifi bars in the lower corner have gone down to 4. My internet is running slower and when I log on and play online games, the local server which gave me a 50 ping is now jumped up to about 300-800 easily...
So I run trouble shooter...
