As vorlorn mentoned, this seems to be a heat related issue. It started when my office's air conditioning stopped working in the tropical heat.
One way I found to solve the problem is to remove the device from the PCI bus and rescan. This seems to re-initialize it to a working state. 1) Wait for the laptop to cool to about 60 degrees celcius 2) Find the PCI bus number using lspci |grep Centrino. In my case : # lspci |grep Centrino 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35) 3) De-activate Networkmanager 4) rmmod iwldvm 5) echo -n 1 > /sys/devices/pci0000\:00/0000\:00\:02.0/remove 6) modprobe iwldvm 7 ) echo -n 1 > /sys/bus/pci/rescan 6) echo -n 1 > /sys/bus/pci/rescan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1036427 Title: unreliability with Centrino Ultimate-N 6300 wireless connection, 802.11n To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1036427/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
