WN2500RP - LAN connections dropping

[Isomil]

I have a WN2500RP setup and the LAN connection continues to drop after around 5 minutes of use on the wired client.

The wireless connections have no issues and can ping other network machines as well as access the internet.

Anything connected on LAN cannot ping other machines on the network.

Any ideas on how to fix this or has the unit died?

Have you tried using a different ethernet cable?
