connectivity issues with dlink dwa 131 wifi adapter

[mukundanks]

i'm facing problems with dwa 131 wifi adapter.it was working fine until last reboot. i have gone through many threads regarding the same. most often i'm getting error with the commands they have given. i'm new to linux btw. also when i try to update through terminal, it says the given package doesnot have release note and so on.

i'm listing the return values of some commands.

Classified Infra 5 270 Mbit/s 17 ▂___ WPA1 WPA2


it was working during the first thread(with very low signal reception), now it is not connecting.

"WPA1 WPA2" is a problem in itself. WPA2 only is what should be. Please check the router settings.

i have corrected in router, but still same result

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.

Then set your regulatory domain 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 (Ctrl+o followed by Enter) and close (Ctrl+x) the text editor.

reconfigured the router, and did everything as you said.

sudo iw reg get
global
country IN: DFS-UNSET
(2402 - 2482 @ 40), (N/A, 20), (N/A)
(5150 - 5350 @ 160), (N/A, 23), (N/A)
(5725 - 5875 @ 80), (N/A, 23), (N/A)

thanks to you, its working now ! sorry for the late reply
