The root cause - from what I understand - was that DHCP failed when negotiating with the router. I enabled static IP for my laptop's MAC and it now connects.

Why that should cause weird behavior in network-manager (like 'connect' button greyed out, as pointed in the bug) is beyond my understanding.

Just as a data point, when dynamic IP was enabled, the laptop would not connect to the router with wicd too.

Could it be a router problem? DHCP works just fine on wired ports.
