which hub did he install the hub 3 and 4 with a solid white light suggests its activated and should be working - there is the hub5 but i dont think techs are installing them - no idea what the light colours on that should be
as to the techs story - that sounds like he wanted away quickly because he knew of a problem - he should have left it working - theres no reports on here of activation problems
try a full reset of the hub - hold the button a good 30 sec dont power off after that let it sort itself out see if that helps
post some info if you can get into the hub
log into hub3 - 192.168.0.1 [or 192.168.100.1 if in modem mode] - DON'T SIGN IN, click - click router status [centre of screen] - and post the downstream and upstream figures - to see those press on the grey buttons/boxes labelled - upstream - downstream
if its an earlier hub button is top right
