(Get the code!)
@bulldozer2003 #173:
What wireless card do you have? (You can find out by running "lspci".) Some models of T440s (especially older ones) seem to have other network cards.
@Bruce #171:
Your dmesg looks almost the same as mine. I also looked into /var/log/syslog which provides more detailed info, but again I don't know what's wrong, given my limited knowledge about wireless on Linux (and I wish there were more useful pointers online).
Larry:
I even thought of modifying Larry's source code to print more useful debug messages. But I don't know how to find useful documentations about wireless drivers on Linux. So I'm unable to help debug. I hope Larry (or someone else) could point me to the right references.
Let me add that I also tried wicd in place of NetworkManager, but it shows pretty similar errors. So this problem isn't specific to NetworkManager. I've also set IPv6 to "Ignore" in NetworkManager, if that matters.
