Should I switch from AT&T internet service to a new ISP based on this speed test?

How often have you run this test?
How many users?

The upload speed is very slow and will cause problems for you.
The new company is slightly better but again, what are you using this for? Internet? Email? Web server?

I live in a remote location and use AT&T's satellite internet from Wildblue

The specs for Wildblue Pro = 1.5 Mbps Download speed.  Up to 256Kbps Upload speed.

The new company is offering = 1.5 Mbps Download speed and 375 Kbps Upload speed.

There is only 1 user (me at home).

The only other choice I have is dial-up, which is slower than satellite.

Who is the new company?

Williams Tel Data (Eric Williams)
La Mesa, California 91942

I cannot find any reviews of that company. Their quoted speeds are better than what Wildblue is giving, but its hard to say whether or not they can deliver. They might be reselling AT&T too for all I know and you might get identical service.

Are they requiring a contract? What service level do they guarantee?

cellular or wimax not an option?

I had the new company install there hardware.  The internet is far faster than AT&T's Wildblue.
