I take it back. The same problem happened with the Atheros wifi card, though it only happened after 8-10 suspend/resume cycles, rather than just 1. But this time, I was able to fix it without rebooting because the problem is not the wireless hardware or driver. It is the ethernet driver:
$ lspci ... 01:00.0 Ethernet controller: Atheros Communications Inc. AR8131 Gigabit Ethernet (rev c0) As mentioned in a previous post, something is not working as expected with the eth0 interface, resulting in quadrillions of errant packets after a resume from suspend-to-ram. So simply reloading the ethernet driver fixes all the networking problems for both ethernet and wifi: $ sudo rmmod atl1c $ sudo modprobe atl1c I've edited /etc/pm/config.d/unload_modules and added SUSPEND_MODULES="$SUSPEND_MODULES atl1c" to see if this fixes the problem. And no, I do not intend to reinstall the Intel 5100 card to see if it works there too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996205 Title: Wireless stops working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/996205/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
