Ok, finally I have managed to find an obscure workaround to this
frustrating bug. Please note, this is not a fix, and it requires manual
commandline intervention which is not supportive of the "it just works"
Ubuntu ideal. There is a root cause problem here that needs code level
fixing. Ubuntu urgently needs to fix this sort of stuff because plainly,
it doesnt "just work" and there is countless people on the Ubuntu forums
actually begging for someone to help them, and having to go through
obscure things to work around the problems.
Root cause problem: eth0 is loosing the gateway after a period of time
in the routing table
Workaround: manually add the gateway address each time it is lost in the
command line
Example:
[EMAIL PROTECTED]:~$ sudo ifconfig eth0 down
[EMAIL PROTECTED]:~$ sudo ifconfig eth0 192.168.10.2 netmask 255.255.255.0 up
[EMAIL PROTECTED]:~$ sudo ifconfig eth0
