I am not using Ubuntu but I suffer this problem with my Asus Zenbook Prime (wireless is Intel Centrino Advanced-N 6235 (rev 24)). In short, either of the following two actions fix the network slowness.
1. Disable 11n capability via `modprobe iwlwifi 11n_disable=1` or the kernel boot option `iwlwifi.11n_disable=1`, depending on whether iwlwifi is a module or not. Everything else works great but you have to use 11g. 2. Disable power management via `iwconfig wlan0 power off` or the appropriate setting in a power management tool, laptop-mode tools, etc. With this option there are still many Tx excessive retries but 11n works otherwise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836250 Title: [Oneiric] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/836250/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
