I use a RT3290 Wireless 802.11n 1T/1R PCIe wifi card. This card does not has a proper driver for ubuntu, I tried several post but I had no luck. Now I've tried to install windows driver for the card using Windows Wireless Drivers, and I have attached the picture.

enter image description here

Here the driver installed properly. But after installation the driver is not recognized by the Ubuntu. Here is the output of sudo lshw -C network

rashed@rashed-HP-250-G3-Notebook-PC:~$ sudo lshw -C network[sudo] password for rashed:

Output of iwconfig is 

eth0      no wireless extensions.

lo        no wireless extensions.

And the out put of sudo modprobe ndiswrapper and then dmesg | grep ndis is 

rashed@rashed-HP-250-G3-Notebook-PC:~$ sudo modprobe ndiswrapper
[sudo] password for rashed: 
rashed@rashed-HP-250-G3-Notebook-PC:~$ dmesg | grep ndis

As you can see, for the wireless card, the the error message -network UNCLAIMED is there. Now if any one has a solution for this I would really appreciate to share it with me. Thanks in advance.

  • Please run: sudo modprobe ndiswrapper and then run: dmesg | grep ndis Edit your question to add the result. – chili555 Nov 14 '15 at 19:41
  • Hello @chili555 I have update the post with the result, Please take a look.... – raz Nov 14 '15 at 19:55
  • unknown symbol generally suggests you have the wrong driver files. ndiswrapper needs Windows XP (not 7 nor Vista, etc.) .inf and .sys files appropriate to your architecture; either 32- or 64-bit. Is that what you have? – chili555 Nov 14 '15 at 22:21
  • Hey the driver Id Of my wifi card is PCI\VEN_1814&DEV_3290&SUBSYS_18EC103C&REV_00 and the name is Ralink RT3290 802.11bgn Wi-Fi Adapter. I have driver for windows vista and windows 7 and windows 8 but not for windows xp .. :( – raz Nov 14 '15 at 23:13
  • In most recent Ubuntu versions, this device is driven by the native driver rt2800pci. Is this not working for you? – chili555 Nov 15 '15 at 01:46
  • Hey I found a driver for windows xp the link is http://devid.info/p467380/Ralink+RT3290+802.11bgn+Wi-Fi+Adapter . And I have update the post with recent result from the terminal .... have a look please. – raz Nov 15 '15 at 07:29

Run the following command: 

sudo modprobe ndiswrapper

If this show you "Required key not available",then follow this link. I don't have much knowledge of Ubuntu but this fixed my problem.
