WRT54g Internet IP

[adgish]

I am unable to get an internet IP assigned to my Linksys WRT54g
(Version 5) router. However, my PC is able to get an IP address when I
plug it into the internet. My ISP has a no router policy. The router
has the same MAC address and hostname as my PC, so there must be some
other way the ISP is determining that it is a router and not a PC.
Does anybody have any idea what this could be? Thanks, Gish

Gish,

This sounds like a MAC address problem. You need to reset the modem, so it will
recognise the router.

Your ISP can "see" a computer (or more) with the router assigned IP
192.168.1.100 (or .101 etc) while your PC's IP can be only 192.168.0.2 to
192.168.0.254. You cannot hide your IP from your ISP since you need an
address where the packets of data must be sent. A work around might be to
try ISP->Modem->server (your computer)->router->network - I never tried it,
so I cannot say if it would work.

What kind of Internet connection do you have? If you are in the US and
have DSL and are using an ISP-supplied "DSL modem" you probably have a "UHP
modem" that is set, by default, to act as a one-port router. It's my
understanding that most cable modems also act this way.

Linksys, on the other hand, expects that a DSL connection is made through a
modem acting as a bridge -- which is how almost all of the early DSL modems
were set up. Thus, the DSL setup for the WRT54g asks for your ISP
username/password, and the WRT54g attempts to establish a PPPoE
connection. This fails if the "modem" has already established the PPPoE
connection and is acting as a router.

The recommended solution is to set your DSL modem to act as a bridge, and
allow the WRT54g to manage the PPPoE connection. Alternatively, you
--may-- be able to get things to work if you set the WRT54g "internet
connection type" to "automatic configuration DHCP"

If you post back, please include:
Your IP address, DHCP server, and Default Gateway when you are successfully
connected to the Internet without the WRT54g (from a command prompt, type
ipconfig /all)
Your ISP
Your connection type (DSL, cable, etc)
The brand and model of the modem -- NOT your WRT54g -- you're using
From the WRT54g "basic setup" screen: (a) connection type; (b) entries, if
any, for host name and domain name; (c) settings for "mtu" and "size" ; (d)
"router ip" local IP address and subnet mask; and (e) "DHCP Server"
setting (enable or disable)
