[AccessD] OT: Three routers, weird problems

 That's the ticket!

 It's running it's connection through the wireless instead of the wired.
Turn your wireless modem off in on the laptop and it will switch to the
wired connection.

 DHCP is separate from the connection point.

Subject: [AccessD] OT: Three routers, weird problems

I have a SOHO.  Yesterday the cable company came in to replace the cable
modem and replaced it with 
an integrated modem / router / wireless.  I like it!  It has guest networks
and so forth, very modern.

I use 192.168.122.1 as that base router's IP and the range 10-100 as the
addresses dished out to 
computers, and I set all that up, turned on encryption, set  the SSID to
C2Db1, all the typical 
setup stuff.

I have a pair of wrt54gs routers / wireless.  I have in the past put them on
the network as access 
points on either end of the house to allow better wireless access around the
house.   I know how to 
turn off DHCP server in the access points, set the IP of the access point
router to a fixed address, 
for which I use 192.168.122.2 / .3 etc.  I set the SSID to unique values
C2Db2 and C2Db3 so I can 
identify each one for connecting.  So I set up two of these "access points"
using two wrt54gs 
routers with the wan / DHCP turned off.  In point of fact, now that I think
of it, I do not know how 
to specifically "turn off" the WAN, I just don't use it, connecting all
cables to the switch side of 
the device.

So now comes the strange thing.

I rebooted and my laptop's wired NIC says it is connecting to the Local Area
Connection C2Db3.  That 
should not be possible, since C2Db3 is not the DHCP server.  C2Db3 is one of
the WRT54GS routers 
which is now only a switch and wireless access point.  The laptop does not
connect to C2Db3 
(directly)  though C2Db3 is plugged into the same gigabit switch as the
laptop (up in my office).

The connection does work, and it gets out to the internet, it is just
confusing to me.  I expected 
that all of my computers with wired connections to switches would show C2Db1
as the network, and any 
wireless NECS would show the name of the wireless access point that they
came in under.

Just as an aside, the "show network map" fails miserably and immediately.
All of my switches are 
dumb (unmanaged) so I was really only expecting perhaps a basic picture of
the network, but nope, 
nothing at all except an error message.

Just as an aside, I have an 8 port gigabit in my office on the second floor
at one end of the house, 
connected to a 4 port gigabit switch in the basement at the center of the
house.  That 4 port is 
connected to the new cable modem / router to get at the internet, and is
also connected to an 8 port 
gigabit switch at the other end of the house (relative to my office).  I
recently "wired the house" 
(myself) putting boxes in the walls of many of the rooms and running
physical cables to the closest 
switches.  It would have been nice to just have a 24 port switch and run
cables all the way to that 
switch but that was not to be.

Anyhoo, I was wondering what the heck the C2Db3 actually means in terms of
what my laptop thinks it 
is doing / connecting to with it's wired NIC.
