I called customer services on Monday about my webspace and was asked if anything else was needed whilst on the call. I said my modem was old and could I have a replacement. I had an ntl:100. He looked up my account and said yes I could and it arrived two days later by courier.
www.speedtest.net gave me 9.5Mb/s twice in the last month on the old modem and so far (only a few days) I get consistently 9.8Mb/s with the new. Shame it took 30 minutes on hold to activate the modem!
The problem I have here is that I called up about four months ago about the slow speeds and an engineer visit was booked. VM cancelled that later the same day as problems were reported in the area. The speed went up to 7Mb/s for about a week following that and then returned to its random high/low speed nature.
Long may it stay at 9.8Mb with the new modem.
