I am seeing very slow speeds on the 2.4 GHz band. Speedtest shows in the low single digit Mbps. 5 GHz is around 500 Mbps. What I've done to troubleshoot. Selected the 40 MHz channel width (based off other posts). Chose channel 11; as it seems 'quieter' using a WiFi Analyzer tool. Rebooted the router. Confirmed no new router firmware updates. Unplugged Access Point to rule out it's not interfering.Read thread V
