I have been with virgin/ntl for about 8 or 9 years, through all that time I have a Motorolla Surfboard Modem SB4100.
My wife and I plus our 4 kids all have pc's so everytime an new speed comes out we upgrade to keep up with everyones demands.
I had an outage tonight which was sorted however I am on the 20mb package and the person on the phone said I would need a new modem as the one I have is not capable of delivering the speed I have.
How pi**ed was I to discover this!
So I wanted to ask if anyone knows what speed my current modem is capable of? If I find out its been under performing for years I will not be happy.
I think overall, its capable of about 13Mbps. So it should have been ok on the 10Mbps service and absoloutly fine on anything below that. Just the 20Mb service it struggles with.
The modem is not suitable for the 20Mb. a lot of people have found out by chance that the modem isn't suitable for the 20Mb they have had for months. I don't think VM have made much effort to make sure that the modems that people have are suitable, and wait for this kind of opportunity to come up before the problem is identified.
ok thanks for that, I did wonder at the time because I never really noticed any great change in speed
Someone will pop up in a minute and say I'm on 20Mb and I have an old SB4100 too. nobody told me that it was no good and I've been using it for months now. how do I get it changed?!
I think that while the SB4100 can theoretically handle 20Mbps, the current QOS 256 system (don't ask, I don't know) can't be supported by that modem, or so an engineer explained.
I had the SB4100, and had to change to a new modem to get the higher speed.
