This is how much speed I can get from Clear wireless internet in last 5 days. It worked up to 6 mbps download and 1 mbps upload for the first week, but then it drastically felt down to 0.25 mbps download and 0.25 mbps upload, which can almost compare to dial-up modems.
Clear support does not care about it's customers, I was on the phone with them for 3 hours in last few days but they just said I'll have to wait 7 working days (probably that means 9 days then..) and someone will call me back. No one did yet..
I tested my computer in Clear store and it worked. I tested my modem in their store and it worked well. The only explanation there is, is that my modem speed is being capped on towers I'm using. It's a rip-off, my internet is exactly 24x (0.25 mbps) slower as promised (6 mbps).
By Clear coverage map my area has one of the best coverages you can get..
