So, a coworker signed up for this newfangled Clear WiMax service that I've been talking about, and loaned me his spare USB dongle so I could give it a test. Initial impression?
AT&T speed test:
Bandwidthplace.com:
DSLReports.com:
Speakeasy:
Speedtest.net:
Pingtest.net:
... bad. Not quite the 6Mbps down, 768kbps up they're advertising.
[Edit]
I'm running the same tests on my normal (6Mbps/768kbps) DSL, over my wireless, just to compare against. I'll just do text this time and skip the images. I chose the same servers to test against as well as I could on each.
AT&T speed test: 4.74Mbps down, 467.94kbps up.
Bandwidthplace.com: 4945kbps down, 479kbps up.
DSLReports.com: 2202kbps down, 473kbps up, 19ms ping.
Speakeasy: 5082kbps down, 487kbps up.
Speedtest.net: 5.09Mbps down, 0.46Mbps up, 24ms ping.
Pingtest.net: 32ms ping, 10ms jitter, 1% packet loss (?).
And, since Pi asked for it, Netalyzr says: We estimate your uplink as having 2300 msec of buffering.
Hm. What's that about?
