The reason you might want to stick with the 192.168.1.* IP address is
because when you have a need to reset to factory defaults, you'll find
it takes some extra steps to reconnect to it (can be done by adding a
slave IP address to the NIC attached to your AP; ip addr add
192.168.1.x/24 dev ethx) to reconfigure. In my case, I simply changed
my internal network to suit the Linksys and never looked back.
I have my set up as follows:

My internal devices (192.168.1.x/24) are attached to the 8-port switch.
I use only 2-ports on the 5 port switch to connect the ADSL modem to the
server. All DHCP, DNS, Firewalling, is done on the CentOS box. I know
most will cringe on the next few words, but I happen to like the way it
is setup. On the ADSL modem, I've set the CentOS box as the DMZ so that
I can control all Nating on the server. It has not failed me for the
last 6 years I've been doing this. The key is to have a deny,allow
firewall policy - meaning the policy on all chains is DROP, then I
puunch the holes I need.
Hopefully not too much verbiage.
Cheers,
Ak.
