I think the `ifconfig_re0=3D=E2=80=9CDHCP=E2=80= =9D=E2=80=99 is superfluous, your interface will be getting assigned its = address by the router using stateless autoconfiguration not DHCP. Perhaps trying to configure both stateless autoconfiguration and DHCP is = upsetting your wireless interface. DHCP is almost never required with IPv6. >=20 > Any clues? >=20 > Thanks -- Bob Bishop rb@gid.co.uk
