The stability of the wireless association is improved throughput is nearly doubled to 240kB/s, but there's some wierdness: it responds to ping from "outside" almost immediately, but when the host pings out, it spaces requests at about 1.6 seconds (which it doesn't do on the alc0 interface). [mini] /usr/src/sys/modules/usb/urtw # time ping -c2 10.0.2.1 PING 10.0.2.1 (10.0.2.1): 56 data bytes 64 bytes from 10.0.2.1: icmp_seq=0 ttl=64 time=36.176 ms 64 bytes from 10.0.2.1: icmp_seq=1 ttl=64 time=44.282 ms --- 10.0.2.1 ping statistics --- 2 packets transmitted, 2 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 36.176/40.229/44.282/4.053 ms real 0m1.696s user 0m0.000s sys 0m0.001s It also takes about 10 seconds for the wlan0 interface to appear after insertion.
