Hi RobD I'm not on wireless no no one is hopping on to my line, but slow speeds occur when the line is busy. Now, Saturday morning, the speed is down to 50KBs whereas is should be over 200. There is no doubt in my mind that it is either a fault on the line or the inability of the exchange to cope with increased traffic.
I have had my line within the house checked by iinet and by my own telco. I have a new modem (Billion 7800N) and a central splitter. Similar problems with Westnet have been reported on Whirlpool so now I'm waiting for Westnet/iinet to get off their butt and fix it.
