Over the past day or two I have noticed that all online games that I play have had lagging connections to the game servers. My ping is low, and my computer is able to run the games, although I am having quite substantial packet loss.
I have included a ping test to the Brawlhalla game servers, but the same problem appears on any game that I play.
Which super hub model do you have and is it in router mode or modem mode? You can login here and click the status top right to post you downstream, upstream and logs. http://192.168.100.1 You could setup a BQM to see if it show anything http://www.thinkbroadband.com/ping
I must admit that your downstream power levels are much much too high, as recorded in your post. However, my tests are, for reasons unknown, not polling the current power level data, so I'm unable to see if they've reduced at all.
Would you take a look though please and let me know if they're still high (anything in excess of +10dBmV) and then reply to my PM (purple envelope icon, top right of page) so that I can arrange for an engineer visit.
