Ok, I removed all machines from the wireless network except the WISP-Dist box and a laptop and ran tcpdump on the WISP-Dist box and started pinging from the laptop.: # tcpdump -i netcs1 -n Kernel filter, protocol ALL, datagram packet socket tcpdump: listening on netcs1 11:12:11.852643 B arp who-has 192.168.4.2 tell 192.168.4.6 11:12:11.852957 > arp reply 192.168.4.2 (0:2:6f:1:5f:27) is-at 0:2:6f:1:5f:27 (0:2:6f:1:89:48) 11:12:12.848877 B arp who-has 192.168.4.2 tell 192.168.4.6 11:12:12.849035 > arp reply 192.168.4.2 (0:2:6f:1:5f:27) is-at 0:2:6f:1:5f:27 (0:2:6f:1:89:48) 11:12:13.848948 B arp who-has 192.168.4.2 tell 192.168.4.6 11:12:13.849102 > arp reply 192.168.4.2 (0:2:6f:1:5f:27) is-at 0:2:6f:1:5f:27 (0:2:6f:1:89:48) 11:12:14.850622 B arp who-has 192.168.4.2 tell 192.168.4.6 11:12:14.850777 > arp reply 192.168.4.2 (0:2:6f:1:5f:27) is-at 0:2:6f:1:5f:27 (0:2:6f:1:89:48) 11:12:15.849210 B arp who-has 192.168.4.2 tell 192.168.4.6 11:12:15.849360 > arp reply 192.168.4.2 (0:2:6f:1:5f:27) is-at 0:2:6f:1:5f:27 (0:2:6f:1:89:48) 10 packets received by filter The 192.168.4.6 and 0:2:6f:1:89:48 really do belong to the laptop so at least the WISP box is receiving correctly... I also noticed that the laptop side shows a RX packets of 0 (using ifconfig) so it's not getting the replies.

"iwconfig", "ip addr", "ip route" etc. Thanks I'd forgotten about the ip *** commands. Could the output from the WISP box be getting stuck before getting out? Also, as an experiment I tried running WISP as an AP. The other machines were able to associate but could not communicate with any others.
