I have high ping to my T3200M router/modem using 5G on mulitple computers and my smartphone. So everything I do on the internet is delayed by 16ms. The problem goes away when I connect with 2.4Ghz or with wired. Neither of those are good alternatives for me. Firmware version is v31.164L.22. Yes I tried rebooting. It has been this way for several weeks. I am using all defaults on the router. Anyone have a solution?
