It's been like a month now since I was "upgraded" to 10mbit but I only got speeds of no more than 4mbit regardless of how many tests I did or applied fixes it was to no avail.
I kept asking BY's technical support whether it was the Webstar cable modem (which they provided) or line that was causing my problem.
But they insisted that nothing was wrong with it even when I had tested it on at least 3 different PCs and kept getting the same slow speeds.
So in a last ditched attempt to sort it out, a m8 of mine (who's also on BY and is experienced with cable modems) came around and see if he could fix it.
When he saw what modem I had he was pretty shocked BY provided me with it because they're supposed to be like the worst ones you can get.
He said that was probably why I was getting such crap speeds, so luckily he brought a spare motorola modem (meant to be one of the best) and hooked that up and you can guess what speed I was getting, BLOODY 10mbit!
If I had told him the manufacturer of the modem much earlier he would've diagnosed the problem straight away and I coud've saved myself so much grief in the long run.
He mentioned BY may have known about the problem with those Webstar modems but gave it anyway as a tactic to reduce congestion on their network.
When I get the chance I'm gonna berate them over the phone (lol) because I always knew it wasn't me that was causing the problem and they made me go through all that hassle for nothing.
I'm just mentioning this for anyone else who may go with BY's 10mbit service and has the same problem that I did with that modem.
