I have a System76 Gazelle, gapz8, running Ubuntu 14.04. My wifi keeps dropping out at random intervals. I have a new router, so I don't believe that's the issue, but I am in an apartment building, so the signals are probably crowded. My computer still registers the wifi as connected, but stops sending and receiving data. I've found that disconnecting from the wifi and reconnecting fixes the problem, but it can happen again within minutes. Does anyone understand the problem or how to fix it? I'm happy to provide more information if that will clarify the issue, just tell me what.

Run the following commands, one line at a time in the terminal (CTRL+ALT+T):
What does this do? The
11n_disable
option disables 802.11n features. Adding it to/etc/modprobe.d/iwlwifi.conf
makes the change persist after reboots (because it will be part of the module config). Themodprobe -rfv
commands are removing the kernel modulesiwldvm
andiwlwifi
, and finally the last linemodprobe -v
is addingiwlwifi
back in.To know what those kernel modules are/do, you can run
modinfo <module name> | grep description
, which will tell you the following:iwlwifi
is an Intel(R) Wireless WiFi driver for Linux (generic Intel drivers)iwldvm
is Intel(R) Wireless WiFi Link AGN driver for Linux (more specific drivers)Other suggestions
Now, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, You may have better luck with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. After making these changes, you may need to reboot the router.
