Many thanks for the help. Yes, wireless LAN works from all my other computers. The Internet is accessible from them. I have a router that does the PPPOE and DHCP and DNS and NTP and a bunch of other things (dd-wrt). I can connect to the wireless LAN via NetworkManager. I am asked for a password. The connection is made. I can ping any ip address including 8.8.8.8. The /etc/resolv.conf contains "# Generated by Connection Manager\nnameserver 127.0.0.1\nnameserver ::1" which does have dnsmasq-base listening on port 53. I checked it (nmap 127.0.0.1 -p 53) and it was open. That seems to make sense, but I have never seen a working NetworkManager setup. So I don't know what to expect. Any more ideas? _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
