I picked up an 831 Ethernet Router for 5$ on ebay just to set up two static IPs on my home network--simple boring. The manual says to hook up my PC one of the ethernet ports and set it to DHCP. This returns a odd DHCP value, 169.254.92.156 or 169.254.50.157. I expected 10.10.10.x
What do you think is going on? Did the last owner config the router with this strange subnet? Or is it borked?
Can I reset the modem without having to get the console cable?
What's more, I assumed this router could set up basic NAT static IP for the ethernet ports. But the manual only mentions DHCP. Searches on NAT and static IP didn't return any How-To or other useful getting started links.
The network is very simple. I have a cable modem and two PCs I want on this router. Any reason I can't expect to fix this?

It's been years since I've played with the 830 series, but if I recall there's 4 LAN ports and 1 WAN port. The 4 LAN ports are grouped together in to a virtual interface called "Ethernet0" and the WAN port will be "Ethernet1".
Honestly, my suggestion on the 831 is to toss it and get an 851 or 871 instead. In addition to the weird interface naming, there's very limited software support both in terms of IOS and GUI-based management. Also, they're limited to something like 4 Mbps of throughput.
