Sometime around October 2021 my internet went down for just over a day. I was told on the phone they had recevied calls from others in the area and someone would be fixing it which they did. Since then I have had huge ping spikes in games most noteably Rocket League where its makes the game literally unplayable at times.
I use a Wired Connection & have also replaced all ethernet cables just incase, also done the basic stuff like restarting the router etc.
I have called twice to get this sorted but haven't gotten anywhere. The first guy I spoke to changed my wifi settings (still not sure why as I mentioned it was happening on a wired connection). So I had to spend an hour resetting all my alexa devices after that.
Second person I spoke to said something about noise and sending a ping or something to my deivce which could take 48 hours but I still have the problem. Included below are the thinkbroadband graphs.
Thinkbroadband graph & live link + router status infomation I see other people post but if there's anything else you need let me know.
