WiFi card not recognized

**austerus** · July 7th, 2011

Hello,

I have a Edimax EW-7711IN b/g/n PCI WiFi adapter and it seems that Ubuntu doesn't recognize it. On the Edimax website it recommends to install DPO_RT3070_LinuxSTA_V2.3.0.2_20100412.tar package which (as I read) is for an USB WiFi adapter.

Could anybody help with an idea?

Thanks!

Please open a terminal and run and post:

Code:

lspci -nn | grep 0280

When we find out it's this: Network controller [0280]: RaLink Device [1814:3060] then we'll install rt3562sta: http://ubuntuforums.org/showthread.php?t=1615304

See post #7.

Thanks!

I will get right on it!

I was trying it while running the system from USB drive, do you think an install survives a restart? (not sure, first time USB-ing) I will probably end up doing an install to HDD but just curious.

Thanks again!

I don't know for sure, but I imagine not. So, was that your device?

That's my device, but it seems there are some issues.

The current file for the chipset on the website was DPO_RT3562_3592_3062_LinuxSTA_V2.4.1.1_20101217.tg z which I installed.

I did the blacklists

Code:

blacklist rt2800pci
 blacklist rt2x00lib
 blacklist rt2x00pci
 blacklist rt2800lib

and then

Code:

sudo su echo rt3562sta >> /etc/modules exit

However, the diagnostic commands you mentioned returned this

Code:

rt3562sta             869831  0

and

Code:

[   21.512617] 
rt3562sta: module license 'unspecified' taints kernel.
[   21.515709] ===> rt2860_probe
[   21.515720] rt2860 0000:02:07.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22

I have a network device ra0 but it is marked as "unknown", not as a wireless adapter.

The interface ra0 is what is created when you compile a driver from source from Ralink; that's normal. Whether it says it's a wireless device or not, it is. Let's see if it scans for networks:

Code:

sudo iwlist ra0 scan

Your readings look pretty solid; nothing screams 'error' or 'fixme.'

Do you see networks when you click the Network Manager icon?

I am USBing myself for the first time, Debian Squeeze. It is interesting to learn a new trick or two.
