Pretty bad during the day, but very good (20-30mbps) at night .... however lately I haven't been able to load YouTube in HD though - even though speedtests are 20mbps+... So I'm scared that us capped Rain Fixed LTE users are being shaped.
I downgraded my package to a 25+25 and left the router at a friend's place.
They just use it for email so dont really notice or care what the performance is, when I last used it a few weeks ago, it was still pretty bad, less than 1mbps a second.
