tp-link WN322G

[Stephen Ho-2]

Hi,

I have just got this particular usb wifi dongle. It seems the driver
just failed with RF MAXIM_NEW_RF 0x8 is not supported. But I am sure
there is a uw2453 rf inside it, 'cos I have cracked it open. Is there
anyway to force the RF driver to use? or I have to modify the code and
compile the driver?

I am running Ubuntu Server with kernel 2.6.22-15-server

Actual error message. "zd1211rw 5-5:1.0: RF MAXIM_NEW_RF 0x8 is not
supported"

Thanks for your help.

Best regards,
Stephen Ho

Hi,

thank you for your information, MAXIM_NEW_RF in TP-Link seems to be
really uw2453 rf, because i made my model working with uw2453
initialization sequence. I only modified zd_rf.c and added rf type to
uw2453.

I am sending tiny patch, you have to be in drivers/net/wireless
directory of linux kernel.

I did not rough testing, but i can scan, i can change essid, i can
connect to WPA PSK ap with supplicant. Also signal meter seems to report
reasonable values.

So, i report with patch in my attachment, TP-Link TL-WN422G (i think it
is the same device as your TL-WN322G, but this does have RP-SMA
connector present, which is reason i bought it), identified as
Bus 007 Device 013: ID 0ace:1215 ZyDAS WLA-54L WiFi

is working.

I dont know other devices with same RF type, if they can be different or
we need different HW initialization, but there is no device in supported
table with this RF, so i cannot compare. It does work for me, YMMV.

Hi,

       Yes... Mine works after that modification(WPA-PSK, WEP). I read
in other mail pluscom wu-zd1211B is also like this.

That didn't work for me, any ideas why? I still get the same error, any help would be appreciated.

I am interested in your comment:

Bus 007 Device 013: ID 0ace:1215 ZyDAS WLA-54L WiFi is working.

If I understand, you have patched a driver to make this device work in Ubuntu or in linux.  If so, this is the only record of success that I can find.  I am very new to linux, but if there is any way I could install your modified driver to make my USB adapter with that chipset work under Ubuntu Hardy 8.04, I would like to try. I would appreciate any help you can provide.
