I can't reproduce the bug because I don't have that router anymore.

arty, as per http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=V42DW=3502854647=BIOSA=precision-m4800-workstation=EN=BI an update to your computer's buggy and outdated BIOS is available (A16). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

I have tried linux-firmware 1.138.1 and the bug still happens. Regarding some other questions: 4d) I confirm: no QoS. It's a very basic router, the most advanced feature is port forwarding. 4f) Some kind of firewall is enabled and it's not possible to turn it off. 4g) I have not tried all the channels, I tried 1, 3, 4, 6, 8, 11.

I cannot adjust WiFi network parameters to see whether this would affect the reproducibility of the bug. However here are more details about network's parameters: 4b) WPA2-PSK 4c) No MAC filtering 4d) No QoS AFAIK 4e) I don't think the router exposes the beacon interval value at all 4f) I didn't enable any firewall on the router 4g) The problem has happened on several channels. 5) At least 4 other WiFi devices do not have problems like this one. 6) The distance to AP was about 3-4 meters 7) The only obstruction was a wooden shelf with big holes like this one http://www.ikea.com/de/de/catalog/products/30275861/ 7a) I could not test this 8) I do not see this problem at work with Cisco APs, however we don't get a big competition for channels at work.

arty, regarding your answers: 4b) WPA2-PSK - If you remove encryption entirely, or adjust it to WPA-PSK/TKIP, WEP does it change anything? 4d) No QoS AFAIK - So, in your router, what options do you have? 4f) I didn't enable any firewall on the router - Does your router have an option to disable this? 4g) The problem has happened on several channels. - Which ones specifically? Did you try them all? 5) At least 4 other WiFi devices do not have problems like this one. - What devices/OSes specifically? 9) I have never tried that with previous releases. I do not have the option to try. - One may test prior releases (live environment is fine) via http://releases.ubuntu.com/ . Saucy would be helpful as it tests the next oldest firmware version for your chipset. 10) Since I have already tried the latest 3.19-rc1 kernel, I don't see the point to test compat-wireless - compat-wireless has the commits from linux-next in them, which is more advanced than 3.19-rc1 (linux-stable). Could you please advise to this? 13) I will try the ndiswrapper later. - Please advise to this as it working rules out hardware failure. 16) I'm using linux-firmware 1.138. I haven't tried the previous version. Latest Intel firmware is from 3/25/2014, I assume it's already included in linux-firmware 1.138. - It's not.

Yes, the firmware is the latest version.

[Bug 1405437] Re: [Dell Precision M4800] iwlwifi regularly loses connection on Intel 7260
arty, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.19-rc1 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
