Wired computer loses connection when set to a static IP

[Kainsin]

My setup:


Router WNDR4500 with latest firmware (1.0.1.6_1.0.24)
Computer: Home built computer running Debian linux, connected to one of the LAN ports on the router.

When I reserve an IP address for this computer then after a while (~12-16 hours, haven't timed it exactly) the connection will be lost and I'm forced to go to the computer and tell it to reestablish the LAN connection. Then it works for another 12-16 hours before losing connection again. I was hoping that the line item mentioning fixed IPs in the latest firmware notes was the reasoning for this problem but unfortunately the problem still persists.

When I don't reserve an IP address for this computer then everything works fine. However since this computer is my webserver I need to be able to forward some ports to it which requires it to keep the same IP.

The computer also had no trouble with a reserved IP on the previous router I used (an old D-Link), so I don't think the computer is to blame here... I have tried configuring it to use a manual IP instead of DHCP but the problem does not go away.

Any help in diagnosing this issue would be greatly appreciated. Thanks in advance.

Setup static ip on pc on OUTSIDE DHCP range instead if you are using address reservation

First - a reserved an ip and a static ip are not the same.
Second - the computer looses it's connection to what? The network? The internet?

Have you tried diagnosing the problem - using ping to see if the computer can contact the other end of the connection and tracert to see where the connection is being dropped.
