I found out it's something to do with the router setting of "renew group key", when it was set to 1 hr, for example, after the router renews the group key, the wl driver becomes very unstable, or NM seems to be connected but actually not.
My workaround is just change the renewal interval to 10hr, which solves the problem in most cases. -- Broadcom STA/wl driver causes random kernel panics https://bugs.launchpad.net/bugs/292450 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
