I literally copied the /etc/hostname.iwm0 file from the working 6.6 installation and have rechecked it multiple times since. If I disable encryption on the access point, it connects. The crazy thing is the iwm interface will connect to an iphone acting as an encrypted hotspot, but not this access point which it worked fine with for years. The failure to connect only occured after I installed 6.7 over the working 6.6 installation, so my guess is that the code changes between releases are responsible for the problem. I have another laptop still running 6.6, that uses the iwn interface. If you think it would be helpful, I can upgrade it to 6.7 and see if it can still connect to the access point. If there is anything else I can try, let me know. -- Brandon Sahlin <[email protected]>
