WAN address of router

How to find WAN (external) IP address of router connected to broadband cable
modem? Router was set as IP Client, to share existing Internet connection in
the network (not NAT). I am not sure does it connection settings was
configured to obtain the IP address automatically(DHCP), or IP address has
been configured manually to some values. It works, but it WEB interface is
not accessible anymore, either via default local IP adress, or via spare
local IP address, neither of them work anymore. Windows configured to obtain
an IP Address Automatically. Is there utility allowing scan local network
and discover EXTERNAL IP address of router?

The proper way would be to connect to your router's configuration page
and check the status link.

A quicker way would be to just go to:

no. problem is that roter has been set in switch mode, just share existing
Internet connection in the network (IP Client). When configuring, there was
alert shown: "Attention: After changes to these settings are applied, the
FRITZ!Box user interface can be reached only via the configured IP address
or the IP address assigned by the DHCP server." But now User interface is
not accessible either via IP address assigned by the DHCP server or by
factory preconfigured IP address.

Putting a router in "switch mode" usually means that the DHCP server
has been turned off and the WAN port is unconnected -- all connections
are made to the LAN ports. Most cable modems are configured to only
give out one IP address (unless you pay more) so this configuration
usually will only work for one device or if it is behind another
router.

In any event, you may be able to connect to your router if you manually
set your computer's IP address to the same subnet as the router was
configured to before switching on the mode (usually 192.168.0.x or
192.168.1.x).

However, most routers have a reset button that will put the router back
to factory default settings when held down for 10 seconds or so with
power applied. This may be the quickest way to regain control of your
router. Check your owner's manual.

in my case, this router have no "reset" button (which would be very handy).
I managed to solve problem, by attaching router to another network which
also uses this type of router. By checking the connected devices I find it
IP address and adjusted it for correct configuration. (NAT roter)

After attaching router back to my PC and configuring Internet connection, I
got another problem, internet connection do not work. All is connected
correctly, I run Internet Connection Wizard on router, but it can no find
where is problem. WLAN connection works. Manual says in NAT mode the TCP/IP
settings need be set to "Obtain an IP address automatically" and "Disable
DNS". This what I have. But in ISP manual for configuring PC Internet
connection is specified that DNS Configuration should be checked "Enable
DNS", Host: ISPname and two IPs of DNS servers(primary and resrved).
How to configure this correctly?

I would phone the ISP and speak to the help desk if you cannot get the
router working normally.

If you are used to setting up routers then it should be fairly obvious why
there is no internet connection - cable not connected, no hardware synch,
incorrect logon details, settings incorrect etc. It might be worh just
contacting the help desk and getting them to check what's up with your
connection/router/pc.

Are the usual router lights lighting up correctly? Are all the cables
plugged in at both ends, pc-router, router-phone socket etc?

If you can logon to the router then check it has hardware synch with the
exhcange - there should be speed readings etc.

If that's ok then check it's connecting to the isp network ok, an example of
this is that the isp has assigned it an IP address but there are other data
that shows this like DNS etc.

Try pinging the router, does that work?

Try pinging google, does that work?

And if you are really stuck then just contact the isp, in 5-10 minutes you
should have internet connection, unless your ISP is terrible (and some are).

See if you can connect via IP address instead of host name. This will
take the DNS function out of the picture. For example, try to connect
to Google as:
http://74.125.53.103
If this works, then you can address your DNS issue by trial-and-error.

Also, whenever you change connections to a cable modem, it is advisable
to cycle power to the cable modem. This forces the modem to release
and reestablish its connections.
