Hello all,

I have been having issues recently with my Deco M9 Plus and I'm not sure how to fix it. The basic issue is that I am getting high speeds when testing and general use, but when gaming, especially League of Legends, I get high ping spikes randomly every few minutes or so. This is making my gaming unplayable. I've put my PC on high priority but that doesn't help.

I've narrowed down the issue to the wireless connection. I plugged in directly to the router with no issue, and also tried using a TP Link Powerline adapter with no issue (although much slower speeds on this). The Deco is one floor below me, literally directly below. Signal is strong and again, I have good speeds when running tests. Also of note, I am only using ONE Deco M9 unit as I have the other 2 in another home. This house is small enough where only 1 is necessary for good signals. 

PLEASE HELP! My old, larger home, did not have this issue with just 1 Deco unit. I'm stumped. There must be some kind of throttling or setting that is hindering me. I also have a TP Link Archer T9E PCI wireless card, but I also tried other wireless cards with the same problem.

PS. Called TP Link the other day, was waiting on speaker hold for 3 hours for a single representative, and then your line hung up on me. That's ridiculous.
