I see that more explanation is necessary. I do know that in theory the 
access point and my LAN are on two different networks. My Linux box is 
both router and DHCP controller. In theory the Access Point is supposed 
to be 192.168.0.50. My LAN is configured to 192.168.2.0/255.255.255.0. 
Despite this, the laptop that is on the LAN is getting it's IP address 
from the Linux box, and is getting out to the net. Somehow, this doesn't 
make sense to me, but that's how it is. I did consider the possibility 
that the Access Point got reprogrammed at some point, and is on the same 
network as my Lan, but if it is, I can't see it - I have tried several 
obvious addresses as Scot suggests in the next reply to my post, but it 
doesn't respond. Is there some scan I can run to try to spot it? I have 
also tried changing my Lan configuration to the 
192.168.0.0/255.255.255.0 range, but, I still wasn't able to see the 
access point - however, I did something wrong when I made the change and 
lost DHCP services to the laptop, so I left something out when trying 
this, and maybe that's my problem. I changed the configuration of eth1 
in the Network admin tool, and changed my settings in the dhcpd.conf, 
when I tried that. Are there other settings somewhere else I missed?

While reconfigured, I did try to reset the access point with the pin in 
the reset hole method, but that didn't change my results. Now, after the 
supposed reset which puts the Access Point to 192.168.0.50, I've put my 
lan back to the original settings of 192.168.2.0/255.255.255.0, and DHCP 
to the laptop is working (it's got 192.168.2.254 assigned to it), and 
I'm getting out to the net - this is baffling my imperfect understanding 
of how this is supposed to work.
