Observe that the default route > is automatically removed. may be you have not understood your own problem yet because so far is nothing to be understood because none of your statements is correct, it is also not FreeBSD's standard behavior and never has been as long as there is the valid IP address on the related interface, no static route will be deleted, you can even boot without cable and the [default] static route is there so you need to explain better your problem in order to understand it probably you have some other stuff running, thirdparty network manager or something, incorrect or incomplete ppoe or dhc configuration or whatever leads to the problem FYI static routes usually are the manually configured routes, so what you say is redundant and not correct, I guess you're loosing some kind of dynamic route since WL networks usually do not run RIP/OSPF/BGP I guess the route you apparently loose is coming from some dhcp server and may be your dhclient configuration is incomplete or none existent, but here now it would be useful to see your config --=20 H +55 11 4249.2222 --------------enig6553937CDC2F6ED5A5FABB6A Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk/eU5kACgkQvKVfg5xjCDyJJwCZAW2CG0LtaF1V8ewiOqHImaKy NHYAn2Rdycv7VqDZ+jpMtH29z+eLC0SR =loUE -----END PGP SIGNATURE----- --------------enig6553937CDC2F6ED5A5FABB6A--
