Title: Wireless B43 - can't connect to open networks
Post by: reidi on December 05, 2010, 12:13:07 PM

This seems backwards, but I cannot connect to open wireless networks, only WPA secure ones.  I know this has worked in earlier TC versions (I am at 3.3 now).  Doesn't matter if I try the wicd solution or just manually loading modules/firmware and iwconfig commands.  I can connect to my WPA network, but not to "open" networks that require no authentication or security keys.

TinyCoreLinux 3.3
Broadcom b43 firmware loaded and works fine for WPA networks.
wireless_tools.tcz  and wireless-2.6.33.3-tinycore.tgz

Actually the problem is that I cannot stay connected.  The wicd gui indicates that I successfully connect, but then indicates I am disconnected again after just a couple of seconds.  The wicd.log file simply shows a successful connection (I think - see below).

This isn't just a wicd problem.  I used to connect to both open and WPA networks using manual commands and scripts (TCL 3.xalpha).  Now I can still connect to WPA networks using those methods, but not to open networks.

I was about to post this yesterday, but I guess I will post it now.

Is the open network yours? If it's not, there may be MAC filtering to only allow selected clients to connect to an otherwise "open" network.

Ummm... embarrassing... For whatever reason the broadcast signals are weaker or my receiver is weaker.  At any rate, moving more into line-of-site with the known open network routers got me connected.  I probably should have known that when I saw I was connecting briefly and then dropping almost immediately.

I didn't retry wicd or wpa_gui but I assume they will work.  I prefer to run lean, and script the few lines required for either an open or WPA connection.
