I can confirm the problem, and also tried to update the kernel to 3.17.3 and use the latest driver 23.11.10.0, but the speed was still much lower than using the 22.24.8.0 so I reverted back.

[Bug 1289961] Re: 8086:08b2 [Lenovo ThinkPad T440s] Power management causes Intel wifi 7260 slowness
OK, I got it. It seems to me that the -8 version has uAPSD disabled. I don't know how to check that. In /sys/module/iwlwifi/parameters the uapsd_disable is set to N but as far I can remember uAPSD was disabled when using -8 version because -8 driver was buggy. Is it a kernel stuff to disable it ? When I use the -9 (e.g. latest 25.228.9.0) version, the download speed is very poor. Ok, I tried to pass uapsd_disable=Y in /etc/modprobe.d/iwlwifi.conf but it does not change the loaded parameter /sys/module/iwlwifi/parameters/uapsd_disable which is still set to N , so I think this parameter is forced by Ubuntu's kernel (that's really out of my knowledge abilities...). SO the workaround which can lead to a fix for this bug, waiting for 15.04 : - run Ubuntu 14.10 with -9 firmware (the default one) ; - remove iwlwifi/iwlmvm modules ; - reload (via modprobe) iwlwifi module with uapsd_disable=Y option ; - the download speed is max ! I read that uAPSD was enabled in -9 firmware because bugs have been busted. Maybe some of them survived ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1289961 Title: 8086:08b2 [Lenovo ThinkPad T440s] Power management causes Intel wifi 7260 slowness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1289961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Francois Thirioux, just to clarify this bug report, this is a regression in Trusty update going from linux-firmware 1.127 to 1.127.10.

[Bug 1289961] Re: 8086:08b2 [Lenovo ThinkPad T440s] Power management causes Intel wifi 7260 slowness
(By far, I do not get any big difference between ping with and without PM. Near by my router, 2.2 ms to 2.5 ms.) I do not know if this problem occurs in prior releases.

Lots of talk about bandwidth, but (IMHO) at least as interesting is ping times (because the results are instantly visible): I'm on a ThinkPad T431s with an Intel Corporation Centrino Advanced-N 6235 (rev 24) 3.13.0-24-generic without PM (pinging my AP): $ ping -c 5 192.168.8.2 PING 192.168.8.2 (192.168.8.2) 56(84) bytes of data. 64 bytes from 192.168.8.2: icmp_seq=1 ttl=64 time=0.882 ms 64 bytes from 192.168.8.2: icmp_seq=2 ttl=64 time=0.948 ms 64 bytes from 192.168.8.2: icmp_seq=3 ttl=64 time=0.960 ms 64 bytes from 192.168.8.2: icmp_seq=4 ttl=64 time=0.768 ms 64 bytes from 192.168.8.2: icmp_seq=5 ttl=64 time=0.848 ms --- 192.168.8.2 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4002ms rtt min/avg/max/mdev = 0.768/0.881/0.960/0.072 ms 3.13.0-24-generic with PM (pinging my AP): $ ping -c 5 192.168.8.2 PING 192.168.8.2 (192.168.8.2) 56(84) bytes of data. 64 bytes from 192.168.8.2: icmp_seq=1 ttl=64 time=96.9 ms 64 bytes from 192.168.8.2: icmp_seq=2 ttl=64 time=17.2 ms 64 bytes from 192.168.8.2: icmp_seq=3 ttl=64 time=39.4 ms 64 bytes from 192.168.8.2: icmp_seq=4 ttl=64 time=61.9 ms 64 bytes from 192.168.8.2: icmp_seq=5 ttl=64 time=84.7 ms --- 192.168.8.2 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4005ms rtt min/avg/max/mdev = 17.298/60.076/96.938/29.065 ms -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1289961 Title: 8086:08b2 [Lenovo ThinkPad T440s] Power management causes Intel wifi 7260 slowness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1289961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
