Router – Netgear router failed (no DHCP addresses served)

netgearrouter

I have a Netgear fvx538. Last night, I found that all the lights were on for IP connections to machines, but the router could not do normal functions: dish out addresses by DHCP, allow connection to internet, etc.

I am not sure what to do with this. Possible options I have not tried:

  1. Use second port for WLAN source

  2. Reset to factory defaults

  3. Connect via RS-232 connection (no
    idea how to proceed with this)

And how can I figure out what actually happened?

Yes, I've tried power-cycling it. Same result: all connection lights on, no machine given an IP address.


Later: it looks like using the second port is the obvious first step:

"The FVX538 has two broadband WAN ports, WAN1 and WAN2, each capable of operating
independently at speeds of either 10 Mbps or 100 Mbps. The two WAN ports let you connect a
second broadband Internet line that can be configured on a mutually-exclusive basis to:

• Provide backup and rollover if one line is inoperable, ensuring you are never disconnected."

I've seen this problem before with the FVX538. In the end, we disabled DHCPd on it, and used a Cisco 2621XM as the DHCP server for the network.
Basically, we came to the conclusion that the Netgear device was running out of memory. You can power-cycle it, and it might work again for a while, but you might then find yourself rebooting the device every few days. We had 3 of the devices, and they all exhibited the same problem eventually. Which is why we ditched them and replaced the DHCP bit with a router (and the Dual-WAN bit too, eventually)
