Sky Broadband exchange informationThis is a discussion on, V1 Router Upgrade: Progress tracking thread within the Sky Broadband help and support forum; Nothing my end, I believe I'm THBZ (Basingstoke)....
From what I can make out, Sky will try to trigger an update in the early hours of the morning, but if you have the router switched off at night, the upgrade within a few days, shortly after you switch it on. So if one day you switch the router on, and between 5 and 30 minutes later, your connection to the Internet seems to die, it would be a good idea not to switch the router off!
You do not need to have the PC on while the update is happening - the router does the update all on its own.
The V1 draws ~5 watts - much the same as a low power night light (and will cost about 10p a week if left on continuously).
Yes, they can get quite warm to the touch. If yours is getting "very hot" then that's a worry. You do have it mounted on its feet with adequate ventilation?
