Can't ping gateway


I recently reformated a linux box and replaced an older version of Slackware with v13.37. The pc is on a local network connected fine with the config. The new install cannot ping the gateway or other pcs on the subnet. The router is a Belkin wireless router. I'm using a fixed IP for the pc in question. When I try to ping the gateway I get "Destination Host Unreachable". I tried with DNS IPs, that did not work either. A second pc with Windows can ping the router. It has a fixed IP of 192.168.2.110.

Netconfig:

Hostname: UnixDev
IP: 192.168.2.9
Gateway: 192.168.2.1
Netmask: 255.255.255.0
Domain: Belkin
DNS: none (not needed)

Route:

Destination Gateway Genmask Flags Metric Ref Use Iface
localnet * 255.255.255.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default 192.168.2.1 0.0.0.0 UG 1 0 0 eth0

"Destination host unreachable" for a local IP means no ARP replies are received.

Could you post the output of ethtool eth0 and route -n?

There's your problem. Check all cabling and the link lights on the NIC and the switch/router.

I replaced the cable to the router, lights on NIC are on, rebooted the router. Problem persists.

This computer was communicating with the LAN before I installed the new Slack distribution.

Do you by any chance have more than one NIC? What does ifconfig -a say?

It could also be a driver issue. What make and model is your NIC? The output from lsmod and lspci -v could be helpful.

Thank you for your help. I think it must be that the network card is no longer supported. Its cheap & very old.
I have a relatively new wireless card which I will try and report back to this thread.

Again thanks.

Problem solved

It turns out the new Slack version no longer supports the old nic. When I replaced it with a newer nic, everything worked. Thanks again for the help I received.
