Networking :: Non-wireless networking problem



My networking (wired) is not working at all.  I have given the same network setup as I have in Ubuntu:

IP address: 192.168.1.8
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
Broadcast: 195.168.1.255
Name server: 192.168.1.1

I can ping the local host but no other machines on the network.

DCHP does not work even though my router has DCHP enabled.

Does anyone have an idea what is wrong or can suggest further diagnostics.

Maybe your network card isn't supported; pinging localhost doesn't need a net card anyway.

Try "ifconfig -a"; does it list eth0?
What is the error when you try to ping something?

I pinged local host just to prove that tcp was up and running.  Here is the full listing from ifconfig

eth0      Link encap:Ethernet  HWaddr 00:16:EC:7F:59:CF  
         inet addr:192.168.1.8  Bcast:192.168.1.255  Mask:255.255.255.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
         Interrupt:10 Base address:0x6c00

lo        Link encap:Local Loopback  
         inet addr:127.0.0.1  Mask:255.0.0.0
         UP LOOPBACK RUNNING  MTU:16436  Metric:1
         RX packets:92 errors:0 dropped:0 overruns:0 frame:0
         TX packets:92 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:7337 (7.1 KiB)  TX bytes:7337 (7.1 KiB)

resolv.conf has the following line in it:

nameserver 192.168.1.1

By the way I am using DSL 4.3.4.  The network card is reported by Ubuntu as Realtek RTL-8139/8139C/8139C+

Tony

Oh, and pinging the other host gives 'host unreachable' of course
I use rtl8139 without issues.
Perhaps an irq issue?
Check with dmesg | grep -i irq

or

cat /proc/interrupts
