I found the Q router awful for holding line sync. When I was on BT with a HH5A + HG612, my line was rock solid and would frequently hold sync for months. Switched to Sky and well the Q router was just rubbish, the longest it ever held sync was about 2 weeks and would frequently just drop the connection.
Went back to my hg612 and hh5 (flashed with openwrt so can use it wherever) to test and back to being rock solid, current uptime with hg612 is 56days. Don't know if mine was faulty or if all the Q hubs are just awful, but mine was horrible. Service is fine, Q hub rubbish.
