Well John you were right things have been changing for me, yesterday voila! my hawei got interferance too.
Now im getting crazy cause i don't know how to solve it.
I know about changing channels on both bands but:
1) im the only user on the 5g band im only 2 meters from the router
2) my phone and microwave woven have been disconnected all this time
3) i have my router on my house second floor
which can be causing this horrible interference?
the 5mh band is precisely for this if you want to avoid interference im only 2 meters from the router, im the only person on the band, i dont get it. =(
