Have you tried with ECN disabled? I have a netgear router that doesn't
work with ECN... but mine doesn't freeze. ECN was enabled by default in
FC2 and it took me awhile to figure out why only TCP was broken on my
FC2 system. Disable ECN by running:
echo 0 > /proc/sys/net/ipv4/tcp_ecn ...
Is that a permement change Nathan, or will I have to put that into the
rc scripts to ensure its disabled on boot?
To make those changes permanent, put a corresponding entry in
/etc/sysctl.conf.
I'll get onto Netgear and findout why tcp_ecn cause the router so much distress. Im running
the latest firmware on the box, and its a very popular brand/model.
I spoke too soon, its better but the problem still exists
I have narrowed it down to DHCP negotiation which is strange as the netgear router is not configured to operate as a DHCP server.
Its not the network card driver as I have now switched to a wireless lan card and the problem is the same .
I get the following in the system log just as the router dies.

192.168.0.242 is an NT box operating as a DHCP server, the reason for that is complicated, to do with limitations
in the netgear DHCP server, I need to be able to set the DNS servers for the DHCP reponse, so that I can have local copies of my
domains on an internal DNS with internal addresses, rather than the external addreses on the external ISP DNS. netgear assumes they are the uptream ISP servers it has DHCP'd from the adsl provider. the DHCP server is disable on the netgear router.
If I set the ip's, DNS's staticaly, then the system is stable.
