AP stops sending Beacons...

I have exactly the same problem. As long as the station (ath1) is connected to another AP on the same channel, the beacons of the ap (ath0) are seen, and a laptop stays connected. As soon as the station goes to another channel, the beacons from the ap stop.

Is there a way I can prevent the station from going to another channel? I tried setting bgscan to 0 for the station, but with no result. I want it to stick on the channel the AP is configured on. For my case, it's even better if the station would not associate, but only listens to neighboring beacons. As all I need the station for is the results of a iwlist ath1 scan. (I can't do that with the monitor interface) Anybody knows a trick/setting for this?

any solutiin?

Anyone can fix it?

exactly the same problem:
ath0 ap
ath1 sta

It is unable to set ath0 to one particular channel - it is changing all the time. When I use "iwlist ath1 scan", ath0 stops sending the beacons and nobody sees it. I need ath1 for scanning other networks (to omit interferences) - unable with ath1 monitor :(

Any update on this? Has anyone found a workaround?

We are having the same problem, we want to scan, so we need a station, but we are primarily an AP. We do not want the station to associate, or to change the channel of the ap, or to stop the ap beacons.

Any idea where to start to look in the code?

Can any of you guys confirm that this issue still exists in (a recent revision of) trunk? I just want to avoid that people are asking for a solution without having tested whether the issue still exists.

I verified this with r3837 on a toshiba satellite P105-S6167 with Atheros AR5BXB61.

If I create an ap and a station, bring up the ap first, it transmits beacons, as soon as I bring up the station it stops (using athstats to monitor).

If I create and ap and a station, but also set the channel of the ap before I bring it up, it will transmit and have the correct channel until I bring up the station. Then the ap changes the channel to the one chosen by the station, and it continues to transmit beacons but now its on the wrong channel.

This issues seem similar to #433, and #980.

With r3837 I notice I do not need a station to do a scan, I can create a single ap on ath0 and get results from iwlist ath0 scan. That didn't work with 0.9.4. That would solve my problem, but as soon as I scan on ath0, it changes the channel of the AP.
