Package: pm-utils Version: 1.4.1-15 Severity: important Hello everyone,
three days ago I upgraded my ~2 months old Jessie system to the current state and around the same time I started experiencing severe problems with my wireless connectivity. First I blamed the poor-quality UPC wireless router and mediocre signal quality, but all other devices worked perfectly so I looked deeper into that and I noticed that somehow my wireless card got into power saving mode. Disabling it instantly solved all problems and the network is usable again. E.g. ping -c 100 google.com: power save enabled: 100 packets transmitted, 94 received, 6% packet loss, time 103229ms rtt min/avg/max/mdev = 21.034/84.491/232.543/36.534 ms power save disabled: 100 packets transmitted, 100 received, 0% packet loss, time 103188ms rtt min/avg/max/mdev = 19.154/25.336/136.978/16.462 ms This example, however, does not reflect the full scale of the problem: anything that needs a little more bandwidth basically stops working altogether. It is likely to be strongly hardware dependent (I'm using Intel Centrino Advanced-N 6235 wireless card on an Asus UX31A laptop), but enabling power saving by default for everything seems to me as a very poor choice, since not everyone has the skill to track down the issue and make the necessary adjustments to prevent the power saving mode being automatically set. I'm not sure whether the change was introduced in this package or somewhere else, but I figured pm-utils is the one responsible for turning it on (in /usr/lib/pm-utils/power.d/wireless) so it should decide whether or not it is the default setting. Could you point me (or reassign the bug) to the right place if I'm mistaken? I'm labeling it only as "important" since I don't even know for sure who or what broke it, but I assume the priority should be bigger since it potentially breaks the wireless networking for many people (at least those with the same wireless card).
