I'm thinking of going on a wild rant here......
Normally I'm about the most positive person you could ever know, but I just cannot think of even one positive thing to say about Clearwire as an ISP.
I had dial-up for quite a few years, there isn't DSL where I live, and when Clearwire built a tower nearby, I signed up.
It was considerably faster than dial-up for the first year or so, then it began to slow down, especially in the evenings. These days, it's quite a bit slower than dial-up most of the time. It's pretty fast at around 6AM, before I go to work, and sometimes it'll be OK after 9:30 or 10PM, but that's getting close to bedtime for me.
I think when my contract is up, I'll very likely go back to dial-up. Sure, it's slower (sometimes), but it's consistent. Clearwire is unpredictable.
Ok, now I'm done with my rant, and I can go back to being my usual self!
