Hi everyone, 
</div>
<div>
 
</div>
<div>
in the meantime I have done some tests with the same setup on a regular laptop (the device used before was an embedded device). On the laptop, the setting seems to work and the legacy devices do not disconnect on a regular basis. Since the laptop has a recent 3.x kernel installed, I was wondering if the ath* drivers could be responsible for the problem I'm experiencing on the embedded device. Can anyone tell me please which version of the ath*-drivers is minimally needed to get it running? Is it at all possible on a 2.6.38 kernel?

Best,

<br />> p2p_go_intent=15
<br />> p2p_go_max_inactivity=300
<br />>
<br />>
<br />> I then run wpa_supplicant with:
<br />>
<br />> wpa_supplicant -Dnl80211 -c /etc/wpa_supplicant.conf -i wlan0 -B
<br />>
<br />> and configure the P2P with:
<br />>
<br />> wpa_cli -i wlan0 p2p_group_add persistent=0 freq=5180
<br />>
<br />>
<br />> This seemed to work at first since both P2P and legacy clients see the network
<br />> and can connect to it. I then noticed, that the legacy devices get disconnected
<br />> regularly after ~5-10 seconds and reconnect again afterwards. Running
<br />> wpa_supplicant with the "-dd" option does not reveal any activity, neither does
<br />> the syslog. If I constantly ping a connected device, it does not disconnect
<br />> though until I stop pinging.
<br />>
<br />> Any ideas on what could be wrong?
<br />>
<br />> Thanks for any help!
<br />>
<br />> P.S.:
<br />> The machine that runs the wpa_supplicant: "Linux device-15 2.6.38.8 #3 Mon Jun
<br />> 24 18:00:26 CST 2013 armv5teb GNU/Linux"
