I just tried by doing the following: 1. re-enabling 11n 2. rebooting 3. disabling powersave => does not work
The PC looks connected to the AP but even google.com will time-out after some time (DNS_PROBE_FINISHED_NO_INTERNET). Tried another website (http://test.com). Very slow connection. After a while, part of the website displays but lots of elements in the page don't show. A look at the console log shows that the browser got a net::ERR_NAME_RESOLUTION_FAILED for the elements in the page that do not show. Let me know if I can help more. The best I could do so far was installing mainline kernel 3.14.1 as well as the related firmware microcode from: http://wireless.kernel.org/en/users/Drivers/iwlwifi But even with this setup, I would still need to disable 11n to get wifi working. So in the end, I wonder if installing the new kernel really had any impact at all. I am not quite sure. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1293569 Title: iwlwifi-7260-8.ucode causes network disconnections problems Status in “linux-firmware” package in Ubuntu: Confirmed Bug description: Running 14.04 (beta) with Kernel 3.13.0-17-generic I've encountered a strange and reproducible error with the iwlwifi-7260-8.ucode firmware. This laptop is a Dell XPS 12 (haswell). With the -8 firmware, it will connect fine to wifi for 30 or 40 mins at a time, then will start dropping connections repeatedly. Even modprobe -r unloading and reloading doesn't fix the issue, only a reboot will temporarily solve it for 40 mins at a time. Moreover, here is what's strange, is during these episodes of disconnection it seems to affect the actual router (2Wire), as the other devices in the house will also start to have issues (very slow connections, limited range,etc). Once I reboot this laptop everything and all devices will return to normal. This issue has been fixed by me manually removing the -8 firware from /lib/firmware and letting the -7 firmware load instead. Since that has been done there has not been a single issue of this happening (now going on 4 days). let me know if there is any other information you would like me to provide.
