I have a home LAN of 4 PCs and 1 laptop.
Connected phone-line --> modem/router --> gigabit ethernet switch -->
PCs ( via CAT5 cable)
Problem: the laptop and 3 PCs connect to the 'Net OK.
4th PC won't even ping the modem/router, although it did access the 'Net
properly a couple of months ago ( when I last used the PC).
However:-
1) if I disconnect this PC from the ethernet switch and connect the
cable directly into the modem/router I can access the 'Net.
2) if I connect the laptop to the LAN cable that is normally plugged ino
the problem PC, the laptop connects to the 'Net
3) if I boot the problem PC from a LiveCD I can connect to the 'Net via
the switc and modem/router.
4) if I change the problem PC from fixed IP to "connect b DHCP" it still
wont connect.
The problem PC has its' /etc/network/interfaces file setup correctly (
verified against other PCs - just different IP).
The problem PC doesn't have a firewall.
All PCs are running Kubuntu - 6.10 in the case of the problem PC.
The ony thing that has changed is the ethernet switch from a 10/100 to a
gigabit switch. The PC's mobo has gigabit LAN.
All PCs have fixed IPs ( fixed to that determined automatically by
DHCP). I have changed the problem PCs IP to match that provided by the
new gigabit switch.
There are no conflicting IPs.
All IPs fall within the range set in the LAN portion of the modem/router.
From above test have determined that there are no problems with the
cables, modem/router or ethernet switch.
Advice please.
