I've been in a private discussion with another Plug member. We have kept it
private because it involves a windows box also but I thought you might like
to see it..... it adds to the knowledge base.

preface:
router- linksys broadband g router
desktop- old computer built in 97 running Linux
laptop- windows xp

I SOOOOO want to dump COX and Verizon so I got a magicjack and a sprint
broadband card. Guess what! It works like a champ:) Now I need to get my
linux box back online before i cancel things (thank goodness for the rebate
and return checks). I figured it would be an easy thing! Just move the
ethernet cord that runs from the router to the modem to run from the laptop
to the router. Guess I was wrng. Darn!

Here is what happens:
When I disconnect the cord from the router to the modem from the modem the
internet light on the router goes out. Then, after I connect said end to the
laptop the internet light goes on but it will not load any pages on the
desktop and it will not ping www.google.com so I suppose this means I have no
connectivity. Hmmmmmmm.... I wonder! Is it set only to recieve? If that is
the problem how do I set it to send?

------
I figured out the problem.... I changed the network and so have to re-run the
setup routine. The problem with that is that it is looking for the router but
the router does not wish to be detected. I think the problem is that the
laptop is plugged into the internet jack and that is plugged into the
desktop. Does that make any sense?

------
You did in deed stumble upon the problem. The ethernet cable from the laptop
"MUST" get plugged into a local port on the router. The internet "WAN" port
is wired different and will not work that way. You then have to have the
laptop share the internet connection by setting the default gateway for the
windows box as the sprint card.

------
that means 2 ethernet cables out of the laptop? If that is the case I'll need
a hub! Let me know if I am correct.

------
No.. Of I am understanding you right the wireless card (Sprint) is a pcmcia
card or USB. That is the new modem. No cord required, unless you have the
Sprint wireless on your home with Diamond shaped antenna, if thats the case
that antenna will go to a modem which gets plugged into the internet
port (WAN) on the router.

Start with all of the equipment you have, so far I know of 2 modems, one for
cox and one for sprint. I need to know which sprint modem you have.

One router is fine. Don't get a hub, don't even hook one up, they are slow and
useless for this.

Then I understand the laptop and desktop will be networked together via the
router. This is where I need to know where the modem (internet connection)
comes in to play and how it is to be attached to the network. Either direct
connection to laptop or to a port on the router. If you send me a model #
from the sprint equipment, I can figure the rest.

------
I am going to try to explain this as simple as possible. If I lose you, let me
know!

Laptop is Windows XP. Wireless card is connected to this machine. In Control
Panel | Network Connections | select the Sprint wireless adapter | select
Properties

From here look for a tab named Sharing. You need to enable other computers to
share your internet connection.

A good practice would be to set up static addresses or reserved addresses in
the router so neither the desktop or motebook change ip's.

Set the Linux box up to use the laptop as the gateway, and by all means forget
about the Wan port on the router. You are connected locally only.

Once you select to share the internet connection, run the ipconfig /all
command in the windows command line. This gives the same output as ifconfig
in Linux.
On the Linux box you need to change the default gateway to the local address
of the sprint card. The ip address of the network card on the Linux box
should be on the same network as everything else, say 192.168.0.x,
192.168.0.x, 10.0.0.x, etc.. If it starts with a 169, you need to enable dhcp
on the router, or make the ip static in network properties for that card.

------
Going to try to explain this one, forgive me if I use some techie words. I
know what I want to say, but I am not the best at teaching it sometimes... :(
The default gateway (for the desktop) is the local address of the device
connecting to the wan (internet in this case). That said if the laptop has 2
ethernet adapters, one being wired (local) and the 2nd wireless (sprint card)
the gateway address is the address of the "wired" adapter. All of the
re-routing to the internet is handled by Windows via Connection Sharing.
A non graphical image would look like this:
desktop (ip:192.168.100.2; netmask: 255.255.255.0; gateway: 192.168.100.1; dns
(primary) 192.168.100.1>>>>>>
laptop eth0 (lan ip:192.168.100.1; netmask 255.255.255.0) wlan0 (wan ip:
xxx.xxx.xxx.xxx; netmask:255.255.255.xxx; gateway: xxx.xxx.xxx.xxx; primary
dns: xxx.xxx.xxx.xxx; secondary dns: xxx.xxx.xxx.xxx) All of the x's will be
replaced by numbers provided by Sprint. You do not have to worry about these
values as you do not want to change these.

So the image would look like this :
desktop>>>laptop (wired port)>>>laptop (wireless card)>>>internet
I am trying to put a nicer diagram together, if you need it.What distro are
you running on the desktop? If I remember right you are running windows on
the laptop and that is what is sharing the internet connection. Just think of
the laptop as a router. Same principal different look and feel. The
connections and pointers all work the same the difference is the software.
Also I would make sure the desktop (if only connecting to internet via
laptop) has dhcp turned off. Then you can set the values to be the same no
matter what.
I will be around all day, feel free to email me when needed.

------
The local addresses can be anything. Because it is connection sharing and not
a business class router the network address in your case is 192.168.1.xxx The
last 3 numbers can be anythig from 1-254 as 0 and 255 are reserved. To see
the address of the wireless, ipconfig /all in windows should do it just fine.
My bad on wlan0, got confused with Linux. The easiest way to get that info is
open control panel | network settings (or for Vista: Network and Sharing
Center) | select Manage Network Connections | select sprint card | right
click | select status

All the info you need should be readable under details. The same holds true
for the wired connections. You can change the settings under properties |
Internet Protocol Version 4 (TCP/IPv4)

------
it doesn't seem to be like that......I got to network connections, right
click the sprint card, and then select status. It does give me two tabs
(general and details)..... I searched around and found where I can set a
static ip..... yipee! (192.168.1.103) Ohhhh.... I get it. BY luck of the draw
I selected 'properties' . What are good DNS servers? ALso, I selected SLIP
for the type of dial up server I am calling. Did I do anything wrong?

------
I don't mean to confuse.... so sorry.
Also, you know how I said I set up a static ip address? Well, that didn't seem
to work. It would not connect this morning until I set 'network connection|
sprint card|ip properties' to 'obtain an IP address automatically'

Ok, looks simple now..
IP address on linux box needs to be 192.168.0.2. The bcast should
automatically change to 192.168.0.255 and netmask should be left as is. The
gateway should be 192.168.0.1, if that don't work try 68.27.190.219.
You do not have to configure the dns servers in linux unless you want to.
They should be set up for automatic. If not use either the
192.168.0.1address or the addresses on the wireless card dns. This
will be in the
network settings on the linux box.
