I have 2 4-port NAT routers that I want to connect together. The first router or "main" as I'll call it is connected to a cable modem via the WAN port. The 2nd router is a wireless router and will provide wireless access for me.
The main router has DHCP enabled and works fine.
The wireless router has DHCP disabled.
The 2 routers are connected using a "straight through" cable from LAN port to LAN port. I did not use the WAN port on the wireless router because of possible NAT issues.
When I first plug in the wireless router and disable DHCP everything works fine, but inevitably after a few days it'll go "belly up" and I have to RMA it. I've had 4 RMA's back to D-Link for the exact same problem. That tells me that I'm doing something wrong.
First of all I'm wondering if perhaps I should be using a crossover cable.
If it's not the cable, then are there any other considerations that I've been missing that could cause the death of a router?.
