My home town has heavy wifi coverage (lots of students). I typically see 3-8 wifi networks no matter where I am. Of those networks that appear to be open with no encryption, I can usually attach to about 1/3 of them.

I wish we had a tool to show us more information about the connections. I find that most two-bar connections fail. I’d like to know if the connection failed because of MAC filtering, weak signal, too many errors, or some other reason. A blinking W doesn’t do me much good.

I also think that the 770 is very sensitive to wifi signals. It seems to pick up a lot of networks that are too far away to reliably attach to. I see a lot of 0, 1, and 2-bar connections that I can’t attach to. If I do attach, I get an IP address of 0.0.0.0.

Many times I’ll search for networks, find a few, re-search for the networks and some or all of them disappear from the list.
