Hi

I've got a couple of chinese ZBT-WR8305RT, they are based on the MT7620 and they have been discussed previously in this thread
https://forum.openwrt.org/viewtopic.php?id=50466

This devices came preloaded wit 12.09 with pandora box. (Chinese clone)

I've found out this devices are quite difficult to brick, I've been playing with the configurations and a couple times I end up with an unreachable device, I've just downloaded the firmware from the chinese repository (http://downloads.openwrt.org.cn/Pandora … -WR8305RT/) and I was able to recover the device to its original status.

I'm starting to like it because it has 32mb ram and 16mb flash and it's quite cheap $18dll and if you buy larger quantities you get $11 price.


Right now I have the problem I can't set the wireless interface in monitor mode, I would like to run airodump but everytime I tried to add the mon0 I get this:


 airmon-ng start ra0
ps: invalid option -- A
BusyBox v1.19.4 (2014-06-10 23:03:40 CST) multi-call binary.

ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead.  Make
sure RFMON is enabled: run 'airmon-ng start ra0 <#>'
Sysfs injection support was not found either.

I'm confused because airmon shows as the driver being used the Ralink 2560 but when I run the iwconfig

it shows plenty of another interfaces I haven't defined in the network config file and the RT2860v2 as driver.

I have the wifi working properly and the device working as an AP routed, but I want to run the aircrack suite, what I'm missing to put this device in monitor mode?

thank you

Try again with the rt2x00 driver. the proprietary driver does not support monitor mode.

Hi Ps2chiper

How I could install and use the rt2x00 driver?

Thanks.

sp2chiper is right.
mt7620 drivers from mtk/ralink does not support monitor mode.

Kavastudios, hi! Please explain how did you manage to restore your device to original status with original firmware?

Hi. I've pushed 3 seconds the reset button at booting, then i got the restore firmware screen and I uploaded the bin image of the firmware, I've downloaded the image from the chinese openwrt site, it's easy to find, just look for the image belonging to that model.

Hey guys,

Did anyone got this working with monitor mode?

I'm trying to find out if GL-MT300A might be working (has MT7620A 580Mhz SoC).

Thanks.

The discussion might have continued from here.
