I using two VAP:
- VAP AP: ath0 in "ap" mode.
- VAP STA: ath1 in "sta nosbeacon" mode.
When VAP STA (ath1) is connected to another AP, the VAP AP (ath0) bring up and send beacons normally... Everything is OK.
But, when all interfaces running and when I want to scan "the air" by typing: "iwlist ath1 scan", VAP AP (ath0) immediately stops the sending of the beacons until I stop and restart the ath0 interface.
It is obvious when typing "athstats" and monitoring traffic on other computer.
I can reproduce this behavior each time.
My card is a WLM54G from Compex.
