In FreeBSD: kldload ath, ath_hal, bridge, fxp On both host: ifconfig_ath0="inet ssid 1234 channel 6 mode 11g mediaopt adhoc" in sysctl.conf hw....bridge.config=ath0:1,fxp0:1 hw....bridge.enable=1 ipfw allow ip from any to any in this mode speed about 8KBy/s ifconfig_ath0="inet ssid 1234 channel 6 media OFDM54 mode 11g mediaopt adhoc" increase speed up to 45-50 KBy/s Bridging work fine and uptime for both host more wheek under full load :) (40KBy/s over wireless) Some strange - ping report low average delay about 0.700ms for any host in another net segment.

I think this is a driver problem, two ap sucessfully connect with each other, why hostap can't do this ? I tested D-Link 624 WiFi router, D-Link 2100AP, DWL-520+, DWL-G520. On DWL-520+ - acx chipset, it speed not more 8KBy/s with adhoc<=>adhoc connection(but under W2K it have fullspeed 800KBy/s in this mode). I bought DWL-G520 on ath chipset, upgraded hosts hardware up 850MHz processor, new MB, more RAM, but it not resolve the problem, with 54MBit/s connection, speed is too small. D-Link AP, with WiFi router have good connection and speed 38MBit/s(2MBy/s). -- Best regards, Andrey mailto:[EMAIL PROTECTED] _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
