I'm connected to Wi-Fi network but my internet keeps dropping randomly

Question

I am running Ubuntu 16.04 LTS and I have problem with wireless. It says it's connected all the time but randomly, every few minutes, internet is gone and after minute or two it comes back again. All other devices in my home (other computers, phones etc.) have internet all the time.

I ran the script I found on this forum and put it into this Ubuntu Paste bin: http://paste.ubuntu.com/25660911/

Can anyone offer me a solution? Many thanks in advance!

Does it do that with all wireless networks? Do you have other Linux machines connected? — xR34P3Rx, Oct 02 '17 at 14:07
Yes, with all wireless networks and no, this is the only one. — Stefan95, Oct 03 '17 at 16:32

We notice this in your paste:

First, 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 connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Next, I recommend that your regulatory domain be set explicitly. Check yours:

sudo iw reg get

If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:

sudo iw reg set IS

Of course, substitute your country code if not Iceland. Set it permanently:

sudo nano /etc/default/crda

Change the last line to read:

REGDOMAIN=IS

Proofread carefully, save and close the text editor.

Next, I'd set IPv6 to Ignore in Network Manager: http://docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/images/netconfig/network-connections-ipv6-ignore.png This example is for ethernet, but you want wireless.
