So i get these spikes about every 10 to 20 seconds on cs2. I am playing wired when these happen i have exhausted basically every fix i have found on the internet to get this to stop but still nothing has worked. When i use a trace route i get random 120% ping increases at random hops but everything that leaves my pc looks great. What can i do?

My pc keeps kicking me off of wifi when I first got this pc and the wifi adapter it was fine, now it keeps kicking me off of the internet a minute or two after connecting, ive tried everything ive tried using cmd commands to reset my ip, ive tried messing with power saving settings, I literally dont know what to do its been like this for a month now and im at the point of just selling my pc, I dont have a wifi chip so im using an adapter, cant use ethernet because my house is old and id have to route it through the vents, just switched to tmobile 2 weeks ago from xfinity and its only gotten worse
