So I recently purchased a set of Deco x60's from Costco and I'm noticing some strange issues.
1. My pings when doing a speedtest used to be (on my old Asus Wifi5 router) around 12-16ms, my pings are now consistently 25+ms. I've tried changing just about every setting in the books, disabled mesh for my PC, still no change, ping is really high. When I go to DSLReports my bufferbloat is absolutely through the roof (1000+ms sometimes) unless I go into QoS and limit my wifi by over half it's potential speed (I can get 220mbps, but I have it limited to 100mbps).
2. Security setting related, I just noticed this. I was trying to get an HP printer to connect, but could not. The way I resolved that issue was changing my security setting from WPA3-Personal + WPA2-AES to WPA2-AES + WPA-TKIP. Printer connected fine after that, great. But the issue when changing that security setting is my main PC's download is chopped down by over half. When I have WPA2 enabled, my max download speed drops to 40mbps, and the pings/bufferbloat go nuts (both WPA2 and WPA2+WPA settings cause this). When I change the setting back to WPA3+WPA2, speeds back to normal.
Wondering if anybody has any thoughts on how to resolve these issues?
