rt61pci and resume

Hi all,

I'm not sure if this is the correct subforum, but otherwise please move the thread.

So, after resuming from suspend or hibernation, my wifi ping to the router next room becomes mildly absurd (reproducably). The numbers are like ~2ms to the router and ~30ms to websites after a clean boot, and 200-2000ms to both after resuming from a suspended or hibernated state, with packet losses between 2-20%. This will reliably change after another reboot (but not before).

Mobile phones work fine in the same wifi. Windows 7 on the same computer works fine as well.

I also tried setting:

% cat /etc/modprobe.d/rt61pci.conf 
options rt61pci nohwcrypt=1

I will attach some outputs.

However, it happens similar with the standard kernel.

An interesting part of journalctl -b around suspend and resume:

Could the "ieee80211 phy0: rt61pci_set_device_state: Error - Device failed to enter state 1 (-16)" be the problem here?

Re: rt61pci and resume

I tried also the hints from https://bugs.launchpad.net/ubuntu/+sour … bug/323922

Reloading the kernel module with "rmmod rt61pci; modprobe rt61pci" as root seems to help here, so the rt61pci_set_device_state problem could in fact be the culprit here.

Re: rt61pci and resume

iwconfig:

...
          Power Management:off
...

You could try activating power management.
However, I've got the same wifi chipset and had to turn off power management, because the connection was very unreliable otherwise. So activating pm might fix your problem with suspend, but the whole situation might get worse.

Re: rt61pci and resume

Same for me, I actually can only connect with power management off.
