- official sites: clearwire.com clear.com -- different, but not sure about the purpose of each
- Clearwire Blocked Ports Survey: this seems to indicate that Clearwire blocks a number of incoming ports, but this is tentatively contradicted by my own experience (see 2013-01-19 notes below). Perhaps they have different policies in different towns? Also, this undated article seems to be from 2010; they may have changed their port-management policies since then.
Due to an internet outage expected to last all weekend, I finally got set up with Clearwire as an emergency backup, Some preliminary notes:
- receiving email ok (port 25)
- receiving web requests (port 80) but can't access web services at our public IP; have to use etc/hosts to redirect them internally
- able to connect to outside server using ssh/sftp
- the Durham, NC retail location (given only as an address on West Club Boulevard) is, in fact, a kiosk inside Northgate Mall.
- with a signal strength of 2-3 lights, download bandwith was 4+ mbps in one test and ~1.5 in another; upload speed was consistently just under 0.5 mbps. A third test (different applet) gave ~3.5 down and 0.75 up, and a fourth gave 1.65 and 0.68.
- the modem control panel implies a limit of 10 users (presumably enforced by the modem's DHCP server, but that can be bypassed)
