Re:WiFi issue with Tab 4 8 Plus

2020-05-31, 9:28 AM
SOLUTION - I got a brand new Lenovo Tab M8 yesterday and was frustrated it could not find my 5Ghz WiFi although it could connect to the 2.4GHz one. I installed WiFi monitor app (uninstalled app later). I saw it could see few other 5GHz WiFi hotspots but they had a control channel of 36 or 40 or 44 or 48. I logged in to my Asus dsl-ac88u and changed wireless control channel for 5GHz from Auto to 44 and Hurray, the Lenovo Tab MI could find and connect to my 5GHz frequency WiFi. SOLUTION - Set the router control channel to 36 or 40 or 44 or 48. Do not set it to Auto or anything above 52 which are DFS channels.
