If it's any help to you, I persevered with Orange for ages, as we got a good deal thru' my son's mobile contract. However in the end, after FOUR different routers, THREE visits by BT Openreach, I then decided to pay about 20% more a month for my Broadband, but the end product has been absolutely worth it! Also got reduced phone rental & free calls package for a six month period.
One thing you mention is the "Hub"; their latest version (small, slimline piece of kit) has drawn nothing but praise from my mature son. He volunteered, without me asking, a few months ago .......... how did the reception/speed compare upstairs on his state of the art laptop (via dongle)? - he responded that it was consistently a 100% better than anything we had previously. I had to go and have a sit down afterwards, 'cos a response is rare, but praise; well it was the equivalent of a rare comet flashing across the heavens!
