Musíte mít dns na tom modemu? Co máte v /etc/resolv.conf? Případně si něco doplňte do /etc/hosts.

nameserver 192.168.1.1 /IP toho modemu / Máte zaplé dhcp? Jsou místa, kde se s noťasem připojuju, je tam zaplý dhcp, tak si pouštim nějakej skript, kterej nastaví adresu, routu, dns a spustí se ještě ntpdate. Tedy asi to jde líp, stačí mi to takhle.

This option adds a `TCPMSS' target, which allows you to alter the
MSS value of TCP SYN packets, to control the maximum size for that
connection (usually limiting it to your outgoing interface's MTU
minus 40).
This is used to overcome criminally braindead ISPs or servers which
block ICMP Fragmentation Needed packets. The symptoms of this
problem are that everything works fine from your Linux
firewall/router, but machines behind it can never exchange large
packets:
1) Web browsers connect, then hang with no data received.
2) Small mail works fine, but large emails hang.
3) ssh works fine, but scp hangs after initial handshaking.
Workaround: activate this option and add a rule to your firewall
configuration like:
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
-j TCPMSS --clamp-mss-to-pmtu
