Go back to the XB6. I had the XB6 and had no problems with my 1 gig speed, wired is 800-900mbs and wifi is 350-400mbs. I for some dumb reason got the XB7 anyway and immediately noticed slower wifi speeds of 150-250mbs on multiple devices, even my Note 20 Ultra 5G, even tho the connection was wifi 6. The worst part was at random times during the day I would notice everything would buffer or not load, I would run a speed test, and to my amazement I was literally getting 1-5mbs. This went on for 2 weeks, I tried everything, multiple factory resets, separating 2.4 and 5ghz, nothing helped. I switched back to the XB6 and wallah, everything is back to normal, no wifi issues at all. I'm not running out to get the latest gateway anymore, unless I see very little issues on forums in the future.
