I have a relative stable ADSL connection which runs at about 4600kbps, which isn't bad considering we're about 5km from the exchange. Every now and again, though, the throughput on the line gets throttled back to 135kbps, which is not much faster than dialup speed. I've been told that this happens if BT detect a number of line drops in a given period, and it will automatically reset itself in 72 hours.
It doesn't, though, so I have to ring the ISP call centre (in Mumbai) and argue with the morons on the other end of the line who generally don't want to report it to BT. Every time, we have to go through the same script - is your modem plugged into the master socket?, have you any other equipment plugged in?, have you run the BT speed test (which doesn't actually work once the line speed has dropped this low)?.
I'm a relatively calm sort of person, I don't panic and rarely lose my temper (except when Mrs. jereboam is navigating). This problem with the line speed, though, really gets me upset - I get chest pains and asthma attacks after having to deal with these clowns. These days, I tend to go on the attack from the start - if chummy won't listen, I go straight to the supervisor, and give him an earful.
Anyone else have this sort of problem?
