I will be switching to a new cable/Internet provider shortly. Since I need my Internet connection to run Guided Setup again when making this switch, I'm seeking advice from others who may have undertaken this kind of change as to when I should re-run Guided Setup.
Should I do it while I still have my old Internet connection in place, before the installer arrives? Or will I be safe waiting until after both my new Internet and cable connections are wrapped up? I'm assuming that I can confirm operation of the new CableCARDs merely by tuning some of the new channel numbers if I haven't re-run it yet, should the installer need to see that as a measure of success.
Also, any suggestions as to how long it should take for most of my guide data and SPs to get updated?
Thanks for any insights.
