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. There are a lot of different private APs visible in my apartment. 9) I have never tried that with previous releases. I do not have the option to try. 10) Since I have already tried the latest 3.19-rc1 kernel, I don't see the point to test compat-wireless 11) Yes, it occurs in 3.19-rc1 13) I will try the ndiswrapper later. 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. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1405437 Title: [Dell Precision M4800] iwlwifi regularly loses connection on Intel 7260 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1405437/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
