-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I'm hoping this is the right list for my problem, if not, please redirect me ;) I am installing a Soekris net4801 with 3 NICs and a wireless card, using 5.4-REL-p6 and a custom kernel config. My kernel config can be found at http://www.is-root.com/node/62, my dmesg can be found at http://www.is-root.com/node/72 Basically, what I am aiming for with the kernel config is to create a smaller kernel, not supporting hardware the net4801 doesn't have (and will never have) After all is done, and my kernel boots, I am enabling the wireless interface via ifconfig ath0 up ssid my_sid mode 11g mediaopt hostap wepmode mixed wepkey 0xdeadbeef and enabling bridging using kldload bridge sysctl net.link.ether.bridge.enable=1 sysctl net.link.ether.bridge.config="ath0 sis0" sysctl net.inet.ip.check_interface=0 Packets are being forwarded, all is good. When I turn off my regular access point, forcing traffic to go through my net4801, my performance drops. An ftp-session from the LAN that sis0 is connected to tops at 30kilobytes per second, while when I disable the bridge and return to my normal access point, I get speeds in the range of 2.5Megabytes per second. I've searched the net, but am unable to find any clear hints as to where my problem might be, does any of you have an idea ?
