driver RT2870 STA_v1.2.1.0 not working. Wifi adapter SMCWUSB-N LUBUNTU (Ubuntu 15.10)

[thosecars822]

Hello

I have been trying to get this WIFI adapter working under this LUBUNTU (Ubuntu 15.10) with no success so far. Apparently the official website for Ralink devices was closed and I had to try therefore with different versions of the driver RT2870. I found all of them in "driverscollection dot com". The last driver I have tried is 2007_1220_RT2870_Linux_STA_v1.2.1.0. The launch of the command "make" did not end successfully with driver as you can see in the following lines:

  current->fsgid = orgfsgid;

What is more, all of these drivers displayed different errors after launching the command "make". That is why I would really appreciate if you could help me by replying with any suggestion to get this adapter working properly.

Please find attached my file wireless-info.tar.gz with the corresponding information that might give an insight about the problem I am dealing with.

By the way, I know this USB Wifi adapter is not broken because it keeps working great under Windows Vista.

Thanks in advance for any tip or guideline you can think of.

The last driver I have tried is 2007_1220_RT2870_Linux_STA_v1.2.1.0.

rt_profile.c:1370:9: error: ‘struct task_struct’ has no member named ‘fsgid’

What you see here is Linux code for, "Stop. Quit.You can't compile a 2007 antique on my shiny new 15.10 (built in October, 2015) system."

You already have the correct driver, rt2800usb. It scans and sees networks.

I do see this:

Region: Europe/Madrid (based on set time zone)

country 00: DFS-UNSET

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:

gksudo gedit /etc/default/crda

Use nano or kate or leafpad if you don't have the text editor gedit.

Change the last line to read:

REGDOMAIN=IS

Proofread carefully, save and close the text editor.

Reboot with the ethernet detached and tell us what happens.

Thank you for your tip. I appended "ES" after "REGDOMAIN=" in this file "/etc/default/crda" as you suggested, then I unplugged the ethernet cable and I rebooted my computer eventually. For some reason I keep on however seeing this country code "00" as follows after launching the command "sudo iw reg get":

country 00: DFS-UNSET
(2402 - 2472 @ 40), (N/A, 20), (N/A)
(2457 - 2482 @ 40), (N/A, 20), (N/A), NO-IR
(2474 - 2494 @ 20), (N/A, 20), (N/A), NO-OFDM, NO-IR
(5170 - 5250 @ 80), (N/A, 20), (N/A), NO-IR
(5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, NO-IR
(5490 - 5730 @ 160), (N/A, 20), (0 ms), DFS, NO-IR
(5735 - 5835 @ 80), (N/A, 20), (N/A), NO-IR
(57240 - 63720 @ 2160), (N/A, 0), (N/A)

I just created the file wireless-info.txt. I will attach here the recreated file wireless-info.txt

Needless to say the Wifi adapter does not work either after updating the file "/etc/default/crda" as explained.

Thanks in advance for any other suggestion.

I'm having troubles with the pci 3290... have you tried to downgrade your kernel? Some threads about the 3290 suggests to downgrade and that to attempt to build the driver.

He doesn't have the infamous 3290. He has 157e:300e TRENDnet SMC SMCWUSB-N 802.11bgn 2x2:2 Wireless Adapter [Ralink RT2870]

Yikes; just yikes.

Please let us see:

sudo modprobe -r ndiswrapper
sudo modprobe rt2800usb
iwconfig

You have tried a little bit of everything, it appears!

[thosecars822]

The output for the mentioned code

sudo modprobe -r ndiswrapper
sudo modprobe rt2800usb
iwconfig

is the following:

x@x-G31T-M2:~$ sudo modprobe -r ndiswrapper
[sudo] password for x: 
x@x-G31T-M2:~$ sudo modprobe rt2800usb
x@x-G31T-M2:~$ iwconfig
wlx0013f7c99c1b  IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          
lo        no wireless extensions.

ens33     no wireless extensions.

Now the device blinks again but it does not work anyways.

[chili555]

The output for the mentioned code

sudo modprobe -r ndiswrapper
sudo modprobe rt2800usb
iwconfig

is the following:

x@x-G31T-M2:~$ sudo modprobe -r ndiswrapper
[sudo] password for x: 
x@x-G31T-M2:~$ sudo modprobe rt2800usb
x@x-G31T-M2:~$ iwconfig
wlx0013f7c99c1b  IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm

          Power Management:off
          
lo        no wireless extensions.

ens33     no wireless extensions.

So now you have a wireless interface. Does it scan and see networks?

sudo iwlist scan

[thosecars822]

Thank you. I have not found yet any thread for the driver RT2870 that said something about that. What is more, I have never downgraded a kernel before. I'll take a look at this approach. Thank you for the idea by the way.

Which Linux kernel should I downgrade to in order to try the last suggestion?

[chili555]

Then I tried this:
Code:

x@x-G31T-M2:~$ sudo iwconfig wlx0013f7c99c1b essid TP-LINK_AC1980
x@x-G31T-M2:~$

After doing that I logged (http://192.168.1.1) in the router's admin admin website in order to check whether my computer shows up in the list of the devices connected wirelessly to the router. Unfortunately I do not see it there yet.

There is a step missing:

sudo dhclient wlx0013f7c99c1b

It may not succeed with Network Manager running, but let's see what it reports.
