Problems with WiFi connectivity
Hello,
I am a completely new Linux user and I am not sure if this is the right forum to post this issue. But I hope I am doing this correctly. My issue is that ever since I installed Ubuntu 16.10, my WiFi connection is not stable. Every few minutes, pages will stop loading and I have to manually disconnect and reconnect to get them working again. Any leads or help will be appreciated. My Wireless adapter details are as follows. *-network description: Wireless interface product: RT5390 [802.11 b/g/n 1T1R G-band PCI Express Single Chip] vendor: Ralink corp. physical id: 0 bus info: pci@0000:0d:00.0 logical name: wlo1 version: 00 serial: 90:00:4e:65:74:7e width: 32 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rt2800pci driverversion=4.8.0-41-generic firmware=0.40 ip=192.168.0.2 latency=0 link=yes multicast=yes wireless=IEEE 802.11 resources: irq:17 memory:c4500000-c450ffff Regards |
Your wifi hardware could well be relevant here. For example, sometimes it's driver power management at play.
Network PCI (class 02) hardware chipset and driver info can be got by filtering the lspci output like this Code:
/sbin/lspci -nnk|grep '\[02' -A3 |
I think this is the info you are looking for

Looks like an unresolved bug - see here. Interestingly people report it was ok in 14.04.
Keep an eye on the bug entry and see if a resolution pops up. Realtek and Broadcom have a very poor history with Linux support. |
Outstanding bugs notwithstanding, this may be helpful...
http://askubuntu.com/questions/78962...-ralink-rt5392 It mentions creating a custom file eg /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf (or add as a section to /etc/NetworkManager.conf)... Code:
[connection] Code:
sudo systemctl restart NetworkManager https://gist.github.com/jcberthon/ea...c5a95344bc8b55 http://manpages.ubuntu.com/manpages/...er.conf.5.html |
tamalguha,
Welcome to LQ. ferrari is right. You need to disable the wifi-powersave by changing the default setting of 3 to 2. Open a Terminal (Ctrl+Alt+T) and run these exact commands separately. Use Copy and Paste to avoid typing errors! Code:
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf Type it and press Enter once more. NB Your user password will NOT be displayed for security reasons. Now copy and paste the following command into Terminal and press the Enter key. Code:
sudo systemctl restart NetworkManager |
It seems disabling WiFi powersave did the trick. I will observe it for a day to confirm.
Thanks a lot guys. |
Good to know that worked for you. :)

Me too - I hope it is a permanent solution. I saw some threads that suggested it may not be.

I'm having the same problem, however the solution above is not working. Upon checking the log file I see this

Upon running /sbin/lspci -nnk|grep '\[02' -A3 here's the result: Quote:
The wifi was working after fresh install of fedora 25, it stop working after dnf update and then reboot. Please help, thanks in advance! |
