Wireless USB Linksys AE1200 and Slack 13.37


Good morning - I hope you are all enjoying this holiday season.
I have this new wireless-N USB adapter and I'm trying to get it recognized as a network adapter. When I plug it in, I see the following in dmesg:
Code:
usb 2-1: new high speed USB device using ehci_hcd and address 5
usb 2-1: New USB device found, idVendor=13b1, idProduct=0039
usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 2-1: Product: Linksys AE1200
usb 2-1: Manufacturer: Cisco
usb 2-1: SerialNumber: 000000000001
lsusb then adds this entry:
Code:
Bus 002 Device 006: ID 13b1:0039 Linksys
I have rebooted with the device in place and while the above are noted, no wireless adapter appears to be created. ifconfig still lists only lo0 and eth0

I've read through several LQ posts
on ralink adapters and
the rt2870 driver.
and took the following actions based on them:
Created /etc/modprobe.d/ralink-blacklist.conf containing
Code:
#gmartin from: http://www.linuxquestions.org/questions/slackware-14/rt2870sta-ko-driver-912689/
blacklist rt2800usb
blacklist rt2800lib
blacklist rt2800pci
blacklist rt2x00usb
blacklist rt2x00lib
blacklist rt2x00pci
and created the link
Code:
ln -L /lib/firmware/rt2870.bin /lib/firmware/rt3070.bin
and restarted the OS after the changes. I see no reference to rt3070 or rt2870 when I run lsmod


Can you recommend my next troubleshooting step? How can i tell what modprobe and the blacklist are doing?

Thanks

Hi gmartin, have you tried to load the module?

Code:
# modprobe rt2870sta
Good luck. ;-)

Thanks - modprobe -v rt2870sta gave me this output

Code:
rt2870sta             433234  0 
crc_ccitt               1347  1 rt2870sta
and in dmesg this:
Code:
rt2870sta: module is from the staging directory, the quality is unknown, you have been warned.
rtusb init --->
usbcore: registered new interface driver rt2870
Should I see a new interface when I run ifconfig? How do I know what interface it is registered as?
FWIW, I added modprobe rt2870sta and modprobe rt2870usb to rc.netdevice, chmod +x rc.netdevice and restarted the OS. The module loaded on restart according to dmesg, but I still don't see a new interface.

Now that the module is loaded let's take a look. Please post the result of the following.

Code:
# ifconfig -a
# iwconfig
Good luck. ;-)

A little searching indicates to me that your wireless chip is a Broadcom BCM43235. There is limited info on this so I could be mistaken. If so, the drivers you have been trying to use will not work.

http://www.wikidevi.com/wiki/Linksys_AE1200


Support for BCM43235 is in the 'no promises' staging section of the kernel. It is called brcmfmac. I'm not sure which kernel first supported this chipset, but as with any driver in the staging section, later is usually better. So see if you can load this driver, and failing that, you could try compiling a recent kernel if you are happy doing that.

It appears that the driver I mentioned does not appear in the kernel that comes with 13.37. The nearest you will get to it is the staging driver brcm80211 (this is looking at 2.6.39.2 which is the oldest kernel I have lying around). The driver brcmfmac does not appear until a later kernel. I would definitely recommend a kernel upgrade if possible

edit: is this a netbook or tablet??

It's a desktop that I want to add to the wireless network.
I followed the link you added above. It referenced a driver here. I downloaded and built the rt3572sta driver and ran modprobe. It inserted the driver, but I found no other change. Added the modprobe to rc.netdevices and restarted with no change in status.

I may try to update the kernel later today.
