US Cable Support > Comcast HSI > New to Comcast, any suggestions?

I know you said you had checked all your connections to make sure they were "clean" - but I wonder how you can do that in terms of checking stuff in the lines from the street to the box? Unless you work for an outfit like Comast - and have those neat little testing gadgets. Like you - we are refugees from AT&T (old Bellsouth) - and whenever I have had problems - my lines always tested clean - even when nothing was working.
