I finally took the plunge. After 4 years of being with a fixed-wireless ISP, I decided to switch to cable. The only reason I had hesitated at all was that I obviously need a static IP address to host my own e-mail, web, and other services.
What I ended up with is Comcast Workplace (business class cable internet). I had been paying $50 per month for the wireless, and this is $74.99 per month, but only $54.99 for the first six months. Now, what about a speed comparison?
This is a speed test before the switch. Note that speed tests of the wireless connection were wildly variable. Sometimes I’d get results like this one, and sometimes it would show a couple megabits. Also, the upload channel was consistently faster than the download.
