I had a similar issue on a mitvstick.
If you are connected to 5ghz, enter your router settings and change the 5ghz frequency from 80mhz to 40mhz and also select another channel such as 164 or something else. Log out and restart/reconnect the wireless network and see if that solves it. It worked for me.
Set the time and date to automatic
