I had syslogd pipe the output to a perl script to set the sysctl, not ideal but effective I hope.

I'm still working on improving my signal but at least for right now it's stable enough to be usable. Try making a little Faraday cage around your router, or put openwrt on it and drop your signal down for your connection. Don't forget to add a dozen random wifi APs and devices. > [jri:/var/log] jisom% ifconfig wlan0 list sta > ADDR AID CHAN RATE RSSI IDLE TXSEQ RXSEQ CAPS FLAG > c0:c1:c0:35:19:88 1 1 26M 8.5 0 1865 29712 EP AQEHTRS RSN HTCAP WPS WME > Thanks, > > > Adrian >
