My router came with a default password on it for the admin account.<br>
The exciting password for the 'admin' account is 'admin'<br>
<br>
I have always wondered if someone was trying to be funny or not.<br>
<br>
In any case, I changed it first thing, before I even exposed it to
the Internet.<br>
As far as a password for the outside world, I don't think it needs
one because your exposure is governed by the firewall. How someone
gains access to install apps on from outside, is beyond my knowledge
level but there was some discussion on PLUG about their being
hacked.<br>
<br>
Unfortunately, I have just discovered that I no longer have a record
of the password I put on the unit.<br>
Ooops. I am a bit red faced.<br>

<div bgcolor="#FFFFFF" text="#000000"> The terms
LAN, WAN, MAN, HAN and such are used very
sloppily. <br>
They can be used to designate the physical
(geographical) area covered by the network.<br>
<br>
Most of them were developed in the early
networking days when computers and communication
equipment was expensive and the physical
distances you could communicate over were
limited.<br>
<br>
Technically, that little Linksys gadget you can
hold in your hands is a LAN server, because the
cabling that it will drive can only go a short
distance. Its input comes from a WAN. In today's
case that would most likely, but not necessarily
the Intenet.<br>
<br>
In your case you have chosen to put your LAN
server between your LAN and your true server at
your Internet Service Provider. In addition, as
I understand it you have an additional modem
server further dividing things up.<br>

If you care Wikipedia has a nice article that
will tell more than you want to know.<br>

I have the same device in my
networking system. My answer may
not be 100% correct, but here is
my SWAG: <br>
<br>
The device was designed to serve
as a router with DHCP server
capabilities, in other words it
hands out IP addresses to requests
that come from one of the output
ports.<br>
<br>
You can access the device using
its web page and turn that feature
off, it then acts as a bridge
router and the DHCP functioning
will come from further upsteam,
from your other router.<br>
<br>
The network will not function
correctly if you have two
different devices trying to pass
out IP addresses using DHCP.
Everything pretty much quits
talking to each other.<br>
<br>
While I have never tried using the
device by plugging everything only
into the output ports, I am
guessing that connection setup
would use the device as a bare
dumb switch. No more double DHCP,
only happy connectivity.<br>
<br>
I am reasonably sure my
explanation is not technically
correct, but is functional. I was
quite loose with input, output,
upstream, and downstream
analogies, but that is the way I
think of them.<br>
<br>
By the way on a separate item, it
is my understanding that most of
these devices are hacked and
infected and should be either
upgraded, or replaced. I have yet
to do either, but I think that is
the case.<br>
