[Kernel-packages] [Bug 1270208] Re: 8086:422b [Dell Latitude E6520] linux-image-3.11.0-15-generic appears to regress connection speed for iwlwifi
The fix for this is to add the following to /etc/modprobe.d/iwlwifi.conf options iwlwifi 11n_disable=8 The problem was caused by the following commit, which disabled TX aggregation by default on the old hardware managed by the iwldvm driver (including our Intel 6300AGN): https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=205e2210daa975d92ace485a65a31ccc4077fe1a Looking at the commit and output of modinfo iwlwifi, passing the value 8 to the 11n_disable parameter forces TX aggregation to be enabled again. After some basic testing, this has boosted my (upload) transfer speed from ~20 Mbps to ~100 Mbps (or equivalently, from ~2.5 MB/s to ~ 12 MB/s). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1270208 Title: 8086:422b [Dell Latitude E6520] linux-image-3.11.0-15-generic appears to regress connection speed for iwlwifi Status in “linux” package in Ubuntu: Expired Bug description: I recently installed 13.10 and immediately updated to the latest updates via my ethernet work connection.

Carl G: I'm not sure I understand the question. A backport is a fix from a later release where the problem doesn't occur, in a release where the problem does. Given Saucy EOLs in ~4 months, you may want to begin using Trusty going forward. Despite this, you may indicate your desire for a backport via a comment. The current Saucy kernel 3.11.0-15 is unusable for me, and i'm forced to boot into 3.11.0-12. That is clearly a regression...

[Kernel-packages] [Bug 1270208] Re: 8086:422b [Dell Latitude E6520] linux-image-3.11.0-15-generic appears to regress connection speed for iwlwifi
I was following jsalisbury's instructions. penalvch - I dont have a burner handy so testing using a bootable cd/dvd is out. I'm happy to install and uninstall a kernel deb to test the Trusty kernel if you can point me at the packages directly. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1270208 Title: 8086:422b [Dell Latitude E6520] linux-image-3.11.0-15-generic appears to regress connection speed for iwlwifi Status in “linux” package in Ubuntu: Incomplete Bug description: I recently installed 13.10 and immediately updated to the latest updates via my ethernet work connection.
