i've had a bad fortnight with airtel. multiple complaints, multiple visits, having to put up with some really stupid suggestions. for example, visiting techs who seem to think that formatting a hard disk is an easy, uncomplicated, and surefire way of fixing windows-xp ka punga which screws up / slows down airtel. (because airtel is perfect and always gives good speeds, the issue _must_ be my two computers.)then there was one call centre clown who, on being told about a few hours of 'adsl link down' said, "sir, [why do they need to say "sir" twice in a sentence? doesn't anybody know how feudal that word is?], there's a small reset button at the back of your modem. press/use it, and the default settings will be installed."(testing him) "and what about the customized settings i've put into the modem? the port forwarding, for example? can you suggest how i might be able to save them, or make a backup?""sir, i don't know about that... i'll ask a technician to make a home visit."so, he doesn't know how to make a backup, yet he's suggesting i wipe my settings out.in industry parlance, i'm told, people like this are affectionately known as "format engineers."anyway, coming to the point. anyone noticed a change in their upstream/downstream settings? mine were at 511/512 till yesterday... a 'ppp down' / outage later (today), the numbers have changed, to 864/864.maybe good times are coming up. "oo la la la la lo lay oh" and all that. if not (and since i get airtel's promised "minimum 64k guaranteed", not the 128 i pay for) i just might shift... but to who? exatt/xbroadband?
