Internet goes bad whenever I join server in video game.

Problem
Whenever I join server in a videogame my Internet speed goes down to 2mbps, skype and the game itself starts to lag (500-2000ms aka unplayable)

Internet Speed
Upload: 1.5
Download: 35-40
Wireless

Things to consider

- I can still download stuff at full speed

- The problem occurs on different games such as Rust (Steam) or Overwatch (Battlenet) so you
can't blame Steam or Battlenet for this issue

- The problem occurs instantly or few seconds later after I join server

- No other devices are using my internet and neither I left torrents or something else downloading or uploading in the background.

- Scanned for viruses

- Tried turning off skype and other programs to see if it helps, it didin't

- Restarted my router twice

- Restarted computer

- I recently had bought different internet adapter since the one I'm using broke, however the one I bought broke in two weeks and the one that was broken started working again. The new one was 5Ghz and the current is 2.4Ghz I have also uninstalled internet adapter software it came with but not drivers since I don't know how.


I'm about to reinstall windows, but perhaps this issue can be fixed without doing so

You need to test on wired. Games are extremely susceptible to small amounts of packet loss and variations in the latency where download are not affect much by that. Wireless can have large amount of loss and packet variations.

Now if you mean you can actually download at full speed while you play the game and only the game has issue then there is something likely wrong that is not actually a network problem. Something in a video driver or something that only appears as a network problem.
