Managed to solve difficulty connecting to 5ghz wifi by changing my router frequency from 80mhz to 40mhz. Very strange that xiaomi in this day and age have problem this with wifi on their modern streaming devices.

Now this buggy device has a new wifi problem. Connection to internet is ok and stays connected while using the mitv stick during the day. The next day after standby overnight the mi tv stick internet is off. The mi tv stick reports wifi is connected but no internet. All my other devices are connected and internet is working. All the ip address and connection details on the mitv stick show the wifi is connected but it can't connect to the internet wwweb.

Every morning I now have to toggle off/on the mi tv stick wifi so it can reconnect to the internet.

Anyone else have this problem and is there a solution for this?

Totally annoyed by this mitv stick with so many network isssues.
