I have just updated to the main line 4.8.4 firmware on my MT6000 I still have an issue where if I select any channel on my 5G wifi connection, my phone wont connect to the wifi. On auto it works fine. Just noticed now that when I set the channel to 140, it wont connect, but if I leave it for a few mins, it then will connect. Then went I switch off the wifi on my phone and then switch it back on again, it then connects. But if I switch my wifi on my phone off for a few minutes, then switch it on again, it will then struggle to connect to my wifi but then eventually does connect. Has anyone else noticed this with the 5G wifi? ---

Are you using 160mhz channels? ---

Channel 140 is a DFS channel. DFS channels (like 140) are shared with radar systems (weather radar, air traffic control, etc.). For most of the world, by law, Wi-Fi routers must scan a channel for radar signals before transmitting on it. CAC (Channel Availability Check), can take 60 seconds or more before the router is allowed to start broadcasting on that channel. Summary: Repeat tests with a non-DFS channel and see. ---

I have upgraded mine to 4.8.4 but I done it via uboot so it’s a clean install. No issues here. Maybe give that a go. ---

Im not using this version of FW, but i really recommend you to go to LUCI and set in there wifi country to be US. In my case GL used DE, and in europe where i live much stricter requirements for power. So just change to wild west ..i mean US and power will increase. ---
