I meant to post this earlier when I talked about Clearwire but forgot. There is one issue that I have not been able to resolve in my limited attempts so far. Clearwire does not have a Usenet server and my attempts to connect to some public Usenet servers are returning errors about not being able to find the server.
I suspect Clearwire may have some ports blocked. I'm not certain why an ISP would block 119 but you never know.
If anyone knows how to get Usenet access through Clearwire, please let me know.
