Too mild for the pit, but…grrr… I’m experiencing exactly the same problems with two different kinds of broadband connection - cable at home and DSL at work (different providers, too); it’s a signal/sync issue; intermittent, so it’s difficult for the engineers to spot (although they have managed to observe the fault in both cases).
Trouble is that the initial attempt (which was very prompt) to remedy the problem didn’t work; after the third engineer visit (in both cases), all that happens is I get a call from the support department asking me if it’s OK to close the call now; I tell them no, because the fault is still in evidence (albeit intermittently, as it always was); they say they will retask the job to the engineering department; a couple of days pass and I get another phone call asking me if it’s OK to close the call now; lather, rinse, repeat.
Maybe someone is running some tests in the interim, I have no way to tell, but this has gone on for nearly a month now; I get the impression they’re out of ideas and hoping the connection will just stay up for long enough for me to mistakenly pronounce it all clear.
