Network suddenly not reachable

Hi,
here's my Problem:
Until yesterday everthing was working perfectly. Today I started my Debian Lenny and internet doesn't work.

I can't ping my router successfully:

Code:

takada:/home/sam# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
From 192.168.1.97 icmp_seq=1 Destination Host Unreachable
^C
--- 192.168.1.1 ping statistics ---
6 packets transmitted, 0 received, +1 errors, 100% packet loss, time 5000ms
, pipe 4

Nor can i ping that computer from another computer in the network:

Code:

DieMaschine:/home/bea# ping 192.168.1.97
PING 192.168.1.97 (192.168.1.97) 56(84) bytes of data.
From 192.168.1.5 icmp_seq=1 Destination Host Unreachable
From 192.168.1.5 icmp_seq=2 Destination Host Unreachable
From 192.168.1.5 icmp_seq=3 Destination Host Unreachable
^C
--- 192.168.1.97 ping statistics ---
4 packets transmitted, 0 received, +3 errors, 100% packet loss, time 3017ms
, pipe 3

This whole thing is really strange because I didn't change any network settings. It just failed to work.
Internet works on every machine except that one.
LED lights are on both on router and on network card of that computer.

Ifconfig says following:

Code:

          inet addr:192.168.1.97  Bcast:192.168.1.255  Mask:255.255.255.0

I really tried to find a solution but I failed. So thanks for any help.

is the network cable securely connected to your system?

Is it connected to your router as well as your computer.
(Most have LED lites to show the connection status.)
Does your router have a USB or serial port where you might see what is happening from the router perspective?

There was a stretch where Intel(R) hardware used a driver iwlagn with known troubles.
I can't comment about other hardware, but you should check that out...
(blush) sorry, you cannot reach the network ...
(giggle) wait, you wrote to this community.

Bonne chance,
