It is pretty simple by using mt7628.ko(or directly use firmware http://vonger.cn/misc/vocore2/20180419V.bin)

First install libpcap.ipk and tcpdump.ipk

Then MonitorMode=2 is MONITOR_MODE_FULL, =1 is MONITOR_MODE_REGULAR_RX, =0 is OFF.

ifconfig mon0 up
iwpriv ra0 set MonitorMode=2
tcpdump -i mon0 -w /tmp/store.cap -vv

or tcpdump -i ra0 -w /tmp/store.cap -vv

The raw data is saved to /tmp/store.cap.
Now we can use wireshark to read store.cap, check the data we get from net. 🙂

PS: CMCC-XXX is everywhere, noise…

Today when I hack the mt7628 driver, I find this hidden feature( maybe not hidden, but at least no documentation at all )

Example come first, if we want 4 different SSIDs in same VoCore2, need to setting up /etc/wireless/mt7628/mt7628.dat

This is only works for mediatek wifi driver mt7628.ko, not sure if mt76 works.

Modify BssidNum, set it to 4.

BssidNum=4
SSID1=VoCore2
SSID2=VoCore2-GUEST
SSID3=VoCore2-HOST
SSID4=VoCore2-NAS

Then reboot, you will find four raX device in your device list.

Now we can use every ra0, ra1, ra2, ra3 same time by one VoCore2. 🙂
And we can setting network, firewall to use them for guest, nas etc…

PS: it support up to 16 ssids, you need to modify its setting in the same file.

Have fun!

mine is working so well.
