I’ve been using a ZTE MC7010 Broadband modem for a little over a year without problem installed by 3 engineer. It’s in Grand Canal Dock and faces a tower. Two days ago out of nowhere the connection has started dropping and all TV streaming is lagging or cutting out. Speedtests range from 400+ upload speeds to no connection and 20%+ packet losses. There is construction in the area perhaps a tower is being impacted? I’ve tried rebooting both the modem and mesh system connected to the unit with no joy.
