If monitor mode is not supported from Linux, then it could be for a reason. AFAIK Linux should allow monitoring on apps like ethereal/wireshark et al. (Unlike WIN). First of all you will need the source of the driver for this tp-link device. Secondly you will need to know what MAC controller/chipset it uses. Then you need to figure out how to put the MAC into promiscuous mode, the chipset vendor could very well have kept that for themselves. I think it also would depend on what you need promiscuous mode for and how it is invoked or by whom/what ? Can you do with just 802.11b ? Because in that case, there are stacks of ZD1201 based wifi USB dongles around, they are easy to set up in Linux. I tried recently with some old Digimate dongles (which enumerated as D-link device) on my SAM9260 embedded target, it was a cinch.

Also when i was searching the internet i found this site http://wireless.kernel.org/en/users/Drivers/otus ; which allows you to run the device on linux but not in monitor mode so can you add monitor mode to this device please and also can you add it to madwifi projectect becauce i do not know how to install the drivers from the site given. thanks in advance. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
