Drop outs

Hi,

Seeing connection drop outs fairly regularly (up to a few times daily).  Could someone take a look please?

Fault present in both modem and router mode.  Equipment is SuperHub 2 (non-AC version).  I moved house in August and was able to do a self-install using my old equipment.  Connection was fine at the previous property.  Self test doesn't flag any issues.

BQM graph showing the issue around 10AM this morning which ties in with the log above (ignore the packet loss around 4PM as I changed the Superhub back to router mode from modem mode): http://www.thinkbroadband.com/ping/share/41b6579a7a6e1331b68bc443b2121865-11-12-2016.html

Re: Drop outs

Engineer attended as arranged and signal levels checked.  SuperHub exchanged for a replacement unit as input feed socket was loose on the board.  Power supply also replaced to eliminate any power issues.  Will continue to monitor.

Re: Drop outs

How's the power levels now? I'm far from an expert, but the previous US seemed a bit low ?
