Being 'old school', I was one of the original broadbanders who opted to buy a cablemodem [from ntl] for a 'mere' £150. The option at the time was rent your modem and pay a total of £24.99 a month or buy your own and pay £19.99. Being a bit of a meanie, I equated that 2.5 years use @ £5 per month saving would 'pay me back' the £150 outlay and anything after that was 'profit'. It worked a treat [until ntl snatched back the £5 discount, though by that time I was well in credit with my CM], my SB3100 was great, until I upgraded to 10meg.
I had no end of problems trying to achieve 10meg and was, eventually, told by ntl that the SB3100 was only capable of up to 6meg and that I needed to replace it. They [CS] told me I could buy one for £50 from the ntlworld shop. I was a bit miffed that, when I upgraded online, nowhere had it stated that I might need another CM but decided that it was worth paying £50 for the full service.
Except, there were NO CMs on the ntlworld shop site.
Annoyed, I went back to CS who put me through to Tech who siad that new CMs was a CS problem and that they should send me one out [for £50]. Back to CS, who dutifully put me back through to Tech who told me to contact CS... FFS!
Somewhat perplexed I felt that I had to find a way to resolve the situation, that was when I discovered online tech assistance from ntl, who, after I'd explained my dilema, said I could source my own CM then let CS know the new details and all would be well.
I found myself an SB5100 [£45 delivered], connected it all up, rang CS who insisted I could not possibly be connected with a non-ntl CM!
Back to the online thang, where I managed to gain a sympathetic ear and once supplied with details, they sorted my connection
Except.... I /still/ couldn't get above 6meg
Furious, I went back to CS, who insisted that there was nothing wrong with my set-up/connection but they'd send an engineer round. The engineer came, could find nothing wrong but swapped out my SB5100 for a 250 [I failed to mention ownership to him
] declared all well and went. Tests later showed I was still unable to get above 6meg! CS suddenly changed tack and suggested that there was a network problem in my area and that the full 10meg would not currently be available...
I was on the verge of completely losing the plot when, out of nowhere, suddenly everything came up to speed [some weeks after getting the 250].
Anyhow, having rambled on a bit, my point was that although, theoretically, you cannot provide your own CM, there are ways and means of getting one connected.
Now, wheres my 20meg?????
