tcp/ip network problems...

Netgear Rangemax 150 wireless router

Specs: Windows 7, 2.4 ghz dual core / 4 gig
First of all, i am really pretty new to networking... i know my way around a computer, but im just not as smart as the rest of you;) Here is the problem that i am having... I recently purchased an older game ( scrabble complete) that i want to play over a tcp/ip network with my girlfriend... However, when we both go into the game, I host, and she joins the network...BUT we cannot ever even see eachother on the network to be able to play against eachother... so after a bit of research... i just dont think i have the computers networked together...

I am able to connect remotely to her computer, and we are both able to get online at the same time, and i can access her shared files from my computer, and vice versa... i have also tried to get the lan working by connecting each computer wired into the router as opposed to wireless... of course you all already probably knew that wouldnt work;)

ANYWAYS... Really, all that i did to try to make this work is change the setting from "automatically detect settings" to
1) ip address on computer A with subnet

(with this set up i was able to ping that ip succesfully and get online succesfully, for a minute, then the connection failed)

2) The second computer had IP settings with the same subnet, however windows 7 would not allow that configuration to go through without starting the network diagnostics tool automatically and changing the setting back to *obtain automatically*...

I also tried another IP but unfortunately, dont remember what one i used ( one i found that someone else had succesfully)

Basically to sum things up, I would LOVE it if someone could give me a step by step on setting up and configuring a tcp/ip... Also if your wondering its tcp/ipv4

Thanks in advance!!!

If both machines are connecting to the same router with Automatically Obtain IP then there would be no need to manually assign IP addresses and those that you selected do not at all resemble the ranges that are normally used by SOHO routers.
Usually they would be in the 192.168.x.x range where the first x is either 0 or 1 and the second x between 2 & 254

If you are able to both connect to internet and see shared folders on each other's machines then there isn't anything wrong with your LAN.

Firstly, are you certain the game employs TCP/IP protocol?
Secondly have you looked at firewall settings in each machine? I'm not familiar with the game you mention but in my experience with other LAN games ZoneAlarm was a particularly un-co-operative firewall. I had to completely disable it before launching any game. Windows firewall seemed to accept LAN connections without too much fuss.

You may have already looked into these things so disregard if you've already been there/done that.

My experience with multi player games is, the person connecting usually has to enter the IP address of the computer hosting the game.

To find out your IP address is (before starting the game) open a command prompt window:

Start >> Run >> type 'cmd' (without the quotes) and then hit [Enter]

and type the following command:

Yup, i am running wondows firewall and had already allowed access to to the game on both systems... Nothing... And as well, when you click to host the game, it asks you to name your session, and gives you your ip address, so on the other system, i obviously click join, and it gives you 2 different options, 1) to choose local.... and 2) you can choose interent and the input the ip address... So i put the ip address in, but no connections every appear...

I believe that our router must be assigning both computers the same IP...( i dont know if this is a legit theory though lol) because when i do an IP search on both computers they both come back as ( dont hack me;) ) haha it will only take someone 9 guesses to guess that last digit;) but the last digit comes back the same on both machines... any other ideas?

**after logging into the router, the IP address assigned to our machines is 192.168.** But like i said the game is recognizing

This sounds like the game is really being hosted on a remote server similar to Halo. One player starts a session and others join in.

Since both players are coming from the same public IP the gameserver is unable to accept the second connection.

You obviously have not followed the advice of CurtR in response 2. If you did you would know that each machine is being assigned it's own LAN IP probably in the 192.168.x.x range. Those "Private" IP addresses are assigned by your router. Your router communicates with the WWW via your modem which has a Public IP assigned by your ISP. ie:

When you launch the game it establishes a connection with a remote gameserver that only sees your Modem IP. That is why both machines appear to have the same IP when launching the game.

Try this. Turn off your modem. Launch the game and select LOCAL as the type of game to play.

Ahhh! i must have forgotten to press the submit button before navigating off the page! Anyway, here it is again... yes i already checked the IP's of both computers through ipconfig, and they are indeed different... 192.168.1.x I attempted turning off the modem provided by my isp, but the game still automatically registered my IP as the same I cannot imagine what i could be doing wrong and why this just refuses to work! Please keep the suggestions coming in, i will try anything! Thanks again!

** I dont know if this helps, BUT when i view my network map, i can see the other computer, but it says that it is unable to placed on the map**
