Trouble with wlan0 monitor mode

[JustSomeGuy]

Okay so this is my first forum post, please bear with me.

Specs:

Pretty much brand new desktop PC running Windows 7

Edimax 11N USB wireless LAN utility (EW-7717Un)

BT5 R3 boot from a USB pen, although perhaps worth mentioning it will only work if I choose the no DRM option.

On typing iwconfig, wlan0 does show up, but all the values provided are 'off', 'no' or '0'. The BT5 wireless manager is picking up nearby networks, however, leading me to believe this isn't a driver issue.

Airmon-ng start wlan0 - nothing happens, it says 'interface, chipset' etc but no details below it.

On typing airodump-ng wlan0 I get 'ARP Linktype set to 1, expected ARP<numbers>' .... 'ensure RFMON is enabled' ...

I also tried airodump-ng mon0 - no such device.

I acquired the BSSID of said network and tried pointing reaver to it with the command

'reaver -i wlan0 -b xx:xx:xx:xx:xx:xx'

Response was 'waiting for beacon from <bssid>' but nothing happens after this.

I also tried 'sudo iwconfig wlan0 mode monitor' and got:

'SET failed on device wlan0; invalid argument'.

The signal strength of the required network is about 80%, and also worth mentioning I don't have an Internet connection at the moment, so any sys files or updates I need are being brought on 2nd USB pen/copied to the C drive so I can use the '1TB file system' to access it if required, although that hasn't proved much use.

It's doing my head in. I just want to get on this network.

Any help much appreciated,

Yours,

When you try to set any value with iwconfig, you first have to bring down the interface wit ifconfig: ifconfig wlan0 down

Then iwconfig wlan0 mode monitor and then ifconfig wlan0 up

Then see if iface is in monitor mode: iwconfig wlan0

Please, you did not submit the sensible info: CHIPSET...It should be rt2770 or rt2870...

Luck..

Ive tried bringing the interface down, changing it to monitor mode, then putting it back up. Ive also tried physically removing the adapter in between doing this.

did you mean to type "iwconkfig wlan0" or did you mean "iwconfig wlan0"? i might be missing a trick,

Also, i did realise after i posted this that i shouldve posted the chipset - first off, its actually an Edimax EW-7622UMN , and so the chipset is a Realtek RTL8192SU .

i just read this http://www.backtrack-linux.org/forum...ad.php?t=49795

and now thinking that maybe its an adapter issue and im going to have to get a brand new one?

Any help is appreciated, guys and girls. Thank you.

Sorry is iwconfig, I modified the post.

As to the chipset, you posted you had a Edimax 11N USB wireless LAN utility (EW-7717Un). But now you say it is a Edimax EW-7622UMN..

Well, with chipset Realtek RTL8192SU, there is one driver but in beta stage, read here: http://linuxwireless.org/en/users/Drivers/rtl819x or you could go to the vendors page and see if there is one driver from them.

As to buy a new one, if you are newbbie and do not want to get in so many issues as to compiling, work-around solutions, etc, I recommend you:
The Alfa 500, Alfa 1 or the Alfa AW36NH (read this post about Alfa AW36NH: http://www.backtrack-linux.org/forum...ight=awus036nh).

Luck.
