Public bug reported:

I can't use wifi with my home router (Netwjork 150Mbps) while plugged off from charging cable.
When I am not plugged into the charging cable wifi might work a while but soon the signal will drop into just one bar and network will become unusable. As soon as I plug back the charging cable the signal also comes back and network is usable again.

I think I do not have this problem with ASUS RT-N53  which I have in the
office.
