@Solla-topee Thank you for the help! I opened my router's page to change the channel and then realised my 2.4ghz wifi was for some reason off so I turned it back on and changed it to channel 1....

My model is TL-WA850RE Roughly a month ago I bought this range extender to plug ethernet into it because my wifi adapter wasn't very good, had really bad ping. It was working fine until at some point...
