VoCore2 Lite Monitor Mode

Thu Jan 19, 2017 8:17 pm

Hi. Has anyone had success setting VoCore2 Lite in monitor mode for wireless packet capture?

airmon-ng reports that chipset is Ralink 2560 PCI rt2500.

aircrack compatibility tables says that "The entire rt2x00 family: rt2400pci, rt2500pci, rt2500usb, rt2800pci and rt2800usb can inject and monitor. Including PCI and USB chips on b/g/n".
http://www.aircrack-ng.org/doku.php?id=compatibility_drivers&DokuWiki=c4a36903831ab7b2c40874416f5f8ea6#compatibility

Seems like it should work. If I try to start capture on airmon-ng, it will say "monitor mode enabled" but iwconfig reports that it is still in "Managed" mode.
Code: Select all
root@OpenWrt:~# airmon-ng start ra0
Interface       Chipset         Driver
ra0             Ralink 2560 PCI rt2500 (monitor mode enabled)
apcli1          Ralink 2560 PCI rt2500
apcli0          Ralink 2560 PCI rt2500

Code: Select all
root@OpenWrt:~# iwconfig
eth0.1    no wireless extensions.
lo        no wireless extensions.

Not an expert on chipsets and drivers, but maybe it is related to missing nl80211?
Code: Select all
root@OpenWrt:~# iw dev ra0 info
nl80211 not found.


System is Linux OpenWrt 3.18.29 #32 Sat Dec 24 22:01:05 CST 2016 mips GNU/Linux with VoCore firmware from 20161224.

Thanks.

I don't own a VoCore2 yet, but I would if it supported monitor mode.

Maybe all of the extra wifi-ifaces are confusing airmon-ng?

Can you try simplifying /etc/config/wireless till there is just ra0 (then rebooting) and trying again?

On some chipsets I've seen, you don't need to even use airmon-ng at all, simply starting airodump-ng on the interface itself is fine and airodump will put it into monitor mode for you (iwconfig ra0 mode montior). Maybe try that seeing if airodump-ng will do it for you anyway? (after simplifying it to just have 1 interface)

LEDE opensource driver support monitor mode.

Please, can anyone confirm LEDE is supporting MT7628 drivers?
According to the other thread, LEDE does not enable wifi interface.
