Mam Gazelę System76, gapz8, z systemem Ubuntu 14.04. Moje wifi ciągle spada w przypadkowych odstępach czasu. Mam nowy router, więc nie sądzę, że to jest problem, ale jestem w budynku mieszkalnym, więc sygnały są prawdopodobnie zatłoczone. Mój komputer nadal rejestruje połączenie Wi-Fi jako podłączone, ale przestaje wysyłać i odbierać dane. Odkryłem, że odłączenie od Wi-Fi i ponowne połączenie rozwiązuje problem, ale może się to powtórzyć w ciągu kilku minut. Czy ktoś rozumie problem lub jak go naprawić? Z przyjemnością udzielę więcej informacji, jeśli to wyjaśni problem, po prostu powiedz mi, co.

/var/log
? Trygrep NetworkManager /var/log/syslog*
, and spend some time trying to understand the messages before reposting. Also, read the "Related" problems along the right side of this screen.Odpowiedzi:
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.

Change the wireless setting of IPv6. I tried it with my laptop, which has been continually dropping the connection, and so far, all day long, I have not had a single dropout! It seems to be working. In Ubuntu, in the top right, click on the wireless network icon that shows connectivity. In the dropdown menu, at the bottom, select "edit connections" and then highlight your wireless connection name. Choose edit, then select the IPv6 tab (to the right of the IPv4 tab) and change the setting from "automatic" to "ignore". Save and exit. Reboot your PC. That took care of my problem, and hopefully will yours, too.

Edit the wireless settings, set the IPv6 method to "ignore".
This may be a very simple solution to this problem. My 12.04 wireless connection dropped out every few minutes when connected over Comcast and sometimes also in hotels. This happened consistently on different Comcast wireless setups. On many other wireless setups, it was solid (in my workplace, at Starbucks, for example).
After struggling with many complicated fixes, I finally stumbled across the above solution: No more dropouts.
Edit by cipricus to add images (in KDE Plasma 5.8 interface):

/etc/NetworkManager/system-connections/*
I can confirm that this translates into the samemethod=ignore
. Unfortunately this did not fix things for me.I found a good article on this at: http://itsfoss.com/speed-up-slow-wifi-connection-ubuntu/
I tried steps 1 through 4, but in the end step 5 (installing WICD) is what worked for me.
I'll quote that section here since it's a solution that I didn't see in the prior answers here:
To clarify, after installing WICD, my WIFI is I think getting disconnected a little less frequently (it was about every 20 minutes), but the big difference is that I previously had to go disable WIFI and then re-enable WIFI to reestablish my internet connection. Now with WICD it just automatically (and pretty much transparently) reconnects within a few seconds.

Hi If you are dual booting or using a PC, firstly ensure your Ethernet does not turn off connection to save power, may not be The Solution but it is one step closer. there are 2 that need turning off. Do this Control Panel/device manager/Network adapters right click Properties / power management/ Un-tick "Allow computer to turn Off this device to save power" Since Windows95 it is always ticked by Default and often when one recovers from a crash it is ticked again and needs to be turned off. Hope it helps

My quick and dirty hack
My wifi adapter (Realtek RTL8188CUS) is just angry with Ubuntu and no real solution worked, so I ping my router every 5s:
...and the connection stays on.
