I've tried all solutions online, but still having this issue,

I'm running Xubuntu 16.04,

Here is some outputs :

Linux:~$ dmesg | grep ath10k

In your wireless info, we see this:

The channel, 10, is quite unusual to select as it’s an overlapped channel. We suspect, also because of this, that the router is set to auto channel select:

ath10k_pci 0000:03:00.0: no channel configured; ignoring frame(s)!

Here is an interesting discussion of the pitfalls of auto channel select: https://superuser.com/questions/1311149/why-do-wifi-routers-do-such-a-bad-job-of-channel-selection

Please 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.

We have worked on some cases where a space in the name of the SSID was detrimental to connectivity. I suggest that you rename the SSID to FLAT_DX or FLATDX or some such.

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.

Is there any improvement?

  • Still the same issue, changed the SSID to FLATDX , Chanel 6, 20Mhz, AES, BGN RegDomain to IS (Temporary)

  • Are you located in Iceland?? Then why IS?
