Well with my various posts about problems with TalkTalk I should probably point out that I did sign up. Less than a month later and it’s now live. And contrary to my expectations everything seems fine.
My router reports a connection speed of about 2.2 Mbit/s and I’ve had a combined download speed of about 120KB/s (including about 50KB/s from a peer-to-peer program). The only negative thing is that my modem and start up pack hasn’t arrived (my official go-live date was yesterday) but since I have a router and I’m perfectly capable of setting it up that’s not a major problem).
Also, my upstream bandwidth is apparently 288 Kbit/s. Not wonderful but good enough to stream reasonable video (I’ll post more about a cool app called Orb some other time.
