TP-Link TL-WN422G doesn't recognized

[mkrisz]

Dear forum members,

I have the following problem. I have a TP-Link TL-WN422G wireless USB device (I'd like to use this because it has an external antenna slot), but it's absolutely not recognized in Backtrack 3 and Backtrack 4. Please, anybody who had the same problem, help me to install this USB device, I really would need it Please consider that I'm an IT professional, but a beginner in Linux. So please describe the linux driver installation a bit more carefully

Thank you really for your help,
Chris

I have this wifi TP-Link TL-WN422G with Atheros chipset, thus not the one you are writing about and giving links (with ZyDAS chipset).

Chipset is, I think, Atheros AR9271.

The os is BackTrack 4 beta, vmware image. The usb wifi is registered when connected as Atheros communication inc. but no module can recognize it, and no module loads.

Anyone has this one too?

edit: Just to mention, I did update all the wireless modules as shown in the zd1211rw tutorial on aircrack website, no difference whatsoever.

Yes, I've heard about a new version of TP-Link WN422G with a different chipset, but i think that chipset doesn't support injection for now. Didn't researched much, so I can't be sure.

Well, my research for the moment came out with the conclusion that there are no Linux driver for that one yet, neither are there for Mac's, so it turns out to be Windows only for the moment.

Thats pity as it has really nice reception and range... thats what I bought it for in the first place (having also checked that the ZyDAS one worked fine with BT4...) but I will have to figure a way to boost the rt73 one I was using before

This really sucks. I bought this thing because i saw some ppl writing that it works out of the box. But it looks like it isn't possible to get the new version "v2" of this stick working.
What do you guys think, should i give it back to the shop, of wait for a driver?

Here some more info:

there are two versions of wn422g+ ,one is zd1211b, another is ar9271.
zd1211b's version is supported by BT4 pre final and any linux distro with kernel 2.6.29 or higher. A modified driver is needed on BT3.
ar9271's version is not supported by linux now, driver of ar9271 is under development,u can find it on git. http://git.kernel.org

Cool, thanks for this info

[trancedrift]

Thanks for the link.

Looks like development is going steady and maybe there will be a driver soon.
