I moved into a new place, and city as well, and was looking to switch from Earthlink to Roadrunner. Not because I had had problems with the former (which I had not), but because I had read that Roadrunner increased the bandwidth of their standard cable setups, while Earthlink hadn't bothered, and I knew I'd be paying the same.
But when I threatened to leave Earthlink, they promised to upgrade my bandwidth from 2 Mbits to 5 Mbits, and give six months half price. So I figured what the hey.
But how can I be sure they really upgraded my speed? Do you know of a relatively trustworthy way of checking your cable bandwidth? I ran the speed test a few times at
http://www.bandwidthplace.com/speedtest/ but the results varied so much that I am not putting much stock on that particular test (results from 2.1 Mbits to 5.4 Mbits on consecutive tests).
Not that the connection is slow or anything.
I tried downloading some betas from Microsoft (because usually M$'s servers are fast to download from and I thought I'd get accurate results) but I didn't notice any difference. I was downloading 3 files, each at around 190 kbps.
