I'm using ubuntu 14.04 64bits, and this wireless pen to connect to the internet.

I've tried to update the driver from RT2870 to RT3070, downloading the latest linux drivers from SMC website.

After that, my wireless networks disappeared and I can't connect.

Here's the output of lsusb when pen connected:

Bus 003 Device 006: ID 083a:a701 Accton Technology Corp. SMCWUSBS-N3 EZ Connect N Wireless Adapter [Ralink RT3070]

The output of nmcli nm:

RUNNING STATE        WIFI-HARWARE WIFI    WWAN-HARDWARE WWAN

running disconnected enabled      enabled enabled       disabled

What's happenning?

Thanks for your help!

Tiago

  • Are you certain the device ID isn't 083a:a701? If so, please edit your question. What about the default rt2800usb was not working as expected? – chili555 May 30 '14 at 21:45
  • thanks chili555, in fact the id was wrong. Just edited the question. The original driver was always dropping the connection, so I went to the website to download the latest drivers. – DJames Jun 2 '14 at 17:05
  • help would be very appreciated...at least to rollback to the old driver...otherwise I'll have to make a clean ubuntu install...thank you! – DJames Jun 3 '14 at 11:33

I am surprised you got the driver from SMC to compile at all. Let's try to uninstall it. Please open a terminal and do:

cd ~/Downloads/Release2010

...or wherever you downloaded and extracted the file if not Downloads. Press Tab and let the remainder of the long filename fill in; press Enter.

cd Drivers/Linux

I assume you extracted the RT3070 tar file within.

cd 2009

Press Tab and let the remainder of the long filename fill in; press Enter. Now, finally, we uninstall:

sudo make uninstall

If the original 'make' failed, then there is actually no need to uninstall.

Did you blacklist the native driver?

gksudo gedit /etc/modprobe.d/blacklist.conf

If you do not have gedit, use leafpad, kate, nano or any text editor. If you have blacklisted rt2800usb, remove that line. Proofread carefully, save and close the text editor. Reboot and tell us your symptoms. We'll troubleshoot from there.

  • this is the output of make uninstall, I also removed the rt2800usb from blacklist.conf and the output of lsusb and nmcli nm remains the same. – DJames Jun 3 '14 at 16:36
  • ~/drivers/SMC/2009_0525_RT3070$ sudo make uninstall make -C /home/posto-11/drivers/SMC/2009_0525_RT3070/os/linux -f Makefile.6 uninstall make[1]: Entering directory /home/posto-11/drivers/SMC/2009_0525_RT3070/os/linux'_ *rm -rf /lib/modules/3.13.0-27-generic/kernel/drivers/net/wireless/rt3070sta.ko_ */sbin/depmod -a 3.13.0-27-generic* _make[1]: Leaving directory /home/posto-11/drivers/SMC/2009_0525_RT3070/os/linux' – DJames Jun 3 '14 at 16:46
  • sorry, the unformated comment above – DJames Jun 3 '14 at 16:55
  • Did rt2800usb load? lsmod Is there any informative message? dmesg | grep rt2 and also: rfkill list all Thanks. – chili555 Jun 3 '14 at 19:20
  • I couldn't find any message related to rt2800usb, when making lsmod, probably it didn't boot. made dmesg | grep rt2 and rfkill list all. Rebooted the computer and still remains the same.thanks for your patiente! ;) – DJames Jun 4 '14 at 15:42

I've solved my problem based on How do I make sure the driver for a TP-LINK tl-wn727n is loaded on boot?

After I've made what chili555 told, I've notice that the rt2800usb wasn't loading at boot, so I had to assure that the module was loaded at boot:

sudo modprobe -v rt2800usb

I already had removed the blacklisted drivers from /etc/modprobe.d/blacklist.conf

Next I added rt2800usb to /etc/modules:

sudo nano /etc/modules

Rebooted and my wireless starts up automatically.

Note: when making lsusb my info remais the same:

Bus 003 Device 006: ID 083a:a701 Accton Technology Corp. SMCWUSBS-N3 EZ Connect N Wireless Adapter [Ralink RT3070]

Worked like a charm! :) Thanks chili555!
