Hi All, Since couple of months I'm playing with hostapd on Raspberry Pi 3, prototyping sort of smart access point with multiple SSIDs (each SSID has its own set of routing, security and QoS rules). As soon as only small subset of USB WLAN cards has an AP mode and even smaller subset is able to serve more than one SSID, currently I stick with 2 chipsets: * Atheros-based cards (up to 2 SSIDs), driver ath9k_htc * Ralink-based cards (up to 8 SSIDs), driver rt2800usb/rt2x00usb Additional tools used: * Stock hostapd from Raspbian (ARM) or Debian Jessie (x86_64), version 2.3 * dnsmasq as DHCP server * iptables (for packet mangling and masquerading) * tor daemon (one of SSIDs is to provide Tor routed internet access) * openvpn for tunneled virtual uplinks So the symptoms are: Once initialized (with combination of 2, 3 or 4 SSIDs), AP works fine. But depending on traffic (I've tested it with normal 'gadget-level' internet usage, e.g. listening Internet Radio, watching YouTube, chatting via WhatsApp, etc.) it takes several hours and AP occasionally stops working. It still able to authenticate clients, but no real traffic comes through. The problem appears not simultaneously on all active SSIDs, but one-by-one (the hostapd daemon is not crashing). To restore the functionality hostapd restart is enough, in other words I do not need to fiddle with iptables/routing/tunnels/tor again, just need to restart hostapd and it starts to work again. So I assume (maybe I'm wrong), that the problem is either with hostapd and/or its nl80211 or with the card driver itself. Watching -dd output of hostapd shows nothing unusual. What would be the best approach to debug/pinpoint the problem? I can download hostapd sources and use (for example) CodeLite as IDE for debugging or any other suggested debugger. Thanx a lot in advance, Kirill _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
