Tech Support - Non Game Related .. Sorry

[Ryoushin]

First off I apologize for posting here, I have searched all over and cannot find my answer. I have a windows vista laptop that is connected wirelessly to a wifi location. I want to be able to share this connection via a wrt54g router to my desktop as well as 1 hard wired xbox console and then wireless to another xbox console.

Before all I did was check the box that said "share this computers internet connection" and that was it. Now I cant even get that to work. All I did before was try an set up the laptop as a "router" for my xbox and it worked so I thought why not try and use the wifi recieved from the laptop and share it with the router so that I can use the above.

So I've managed to look all over and can not find the answer I seek. This is what Im trying to do:

1. Laptop that has a wireless connection
2. Have that connection routed through the laptop via ethernet cord to routers "internet" port.
3. Router then allows for internet access across its 4 ports which 2 are used. Desktop and xbox console.
4. Have the wireless portion of the router to send out a signal that my wirelss xbox will be able to use for xbox live.


All this im trying to do prior to the servers back up so my wife and I can enjoy ffxi once again. Any help in this matter is greatly appreciated. Im sorry this isnt game related but, I do hope some of you in the ffxi or ffxiv community are a bit more tech savvy then myself.

Your Router's IP may be getting set as the gateway IP of the network on the clients (especially if DHCP is being used to configure them).

You may need to go in and manually assign IP address, Subnet, and Gateway to use addresses realated to your laptop's network that it has setup through the network sharing.

I think you may be overcomplicating things though. Your router already does what you are trying to get the laptop to do. You may have specific reasons for doing it that way though. But normally the setup is:

ISP modem --> router (by cable in uplink port) --> clients (wireless or wired to switch ports)

Your router is the gateway of your local network, and manages the connection to your ISP's modem, which is the gateway to their network. The ISP sees your router as one device (takes the place of your original PC/laptop as far as they know), even though your router is allowing multiple devices to connect.

In some cases (like with internet phone) you will have to make your router clone the MAC address of your one PC/Laptop that your ISP configured their modem to forward internet traffic to (thus spoofing the modem to treat your router as your PC/Laptop). This is usually on a page in the router's configuration--boxes should be there for either cloning it directly from the PC/Laptop you are managing the router with, or you can input it manually. It may be on an advanced configuration page. It should be detailed in your router's manual if you want to look into this (might be a PDF file on the CD that came with it if you don't have a paper manual).

Ok well let me ask this, since the first time I did this i didnt have to set anything up or modify any settings except to check the box to share the internet connection. Since im not really tech savy, should i leave the LAN ip as auto config and the shared internet on wireless checked, then that would leave me to just go into the router to config the ip , gateway, and subnet? If so, what would you recommend as far as the settings. Because when i did the "router" laptop to xbox wired i had to set the LAN on the laptop to 192.168.0.1 an the sub to 255.255.255.0 an then configure the xbox. those settings are still set on the laptop, so what would you recommend. You seem to have a better handle on this then me. I appreciate your help Raist. /cheer

"share this computers internet connection" is a naughty thing from the days of dialup when very few people had routers. it works, but it isnt what you are trying to do. the router is already doing this.

[Nattack]

192.168.0.1 is the ip address of a gateway, if your laptop has this as its ip there is most likely a rather nasty ip conflict going on

[Ryoushin]

The laptops ip is set to 192.168.1.5 sub 255.255.255.0 gateway 192.168.1.1 dns 192.168.1.1 .. these are the settings i had to imput because automatically gettig a new ip thru windows trouble shorter wasnt working.. the ip 192.168.0.1 sub 255.255.255.0 is whats set on the LAN portion of the laptop which i set so that I could hard wire my xbox to it.

[RAIST]

Your router is likely configured to use 192.168.0.1 with the same subnet of 255.255.255.0 (that means you can use addresses from 192.168.01 to 192.168.0.255). Your router might have taken the first address as 192.168.1.1 also, it's usually one of the two. So if your laptop is using the same base IP, you might have a conflict where both networks are conflicting.

Have you tried not using the shared network feature of your laptop yet to see if it works? If so, then it may well be the conflict situation, in which case you might need to change the IP's a bit. Leave the router as xxx.xxx.xxx.1, but make the laptop end in .2, then each other device higher numbers--but make their gateway the appropriate address for the method you are using:

With the Router as the only gateway, it will have parameters set by the ISP, but will have a local network setup as:
IP: 192.168.0.1
Sub: 255.255.255.0
(this shoulld show in an advanced setup page about the LAN configuration, and you can change if you want)
If DHCP is active on this pagesetup, then you shouldn't need to do anything but set other devices to configure IP automatically. However, if you aren't using DHCP or otherwise need/want to configure them manually, they would need to be IP's higher than the router, and not conflict with any other device. The router in this setup would be the Gateway at 192.168.0.1. If you change the beginning address of the LAN settings, that number changes according to what you set it.

To manually configure devices in this setup, they need to be:
IP: 192.168.0.x (where x is higher than Gateway (router IP), and not conflict with other IP's)
Sub: 255.255.255.0
Gateway: 192.168.0.1

Now, if you are going to force everything through the laptop, this changes things up. Either your Router has a different range for it's nework, or they are the same. If they are different, then just apply the above example, but just make them point to the network in the range of the laptop. IE: Router is on 192.168.0.1/255.255.255.0 and laptop is hosting a LAN on 192.168.1.1/255.255.255.0, make the IP's 192.168.1.x and the gateway 192.168.1.1.

If the laptop is using the same subnet (both the router and the laptop network sharing are both using 192.168.0.x/255.255.255.0) you likely have 2 gateways active. 192.168.0.1 is your router, 192.168.0.2 is your laptop. Same rule applies to manual configuration--but you need to point them to the LAPTOP for the gateway (192.168.0.2). unless your devices have a way to point to a specific DHCP server to auto config themselves (hit and mis, some do, some don't) you will HAVE to configure the IP's manually to force them to the laptop in this setup.

Whew... I think I covered it... been a long time since I've tried to setup a new network...

But, as you can see... it's just easier to let the router do everything for you and not force through the laptop (if you can). Then you just enable DHCP on the router, and let everything use auto config. themselves, and for those that can't auto config, set them manually to an oddball IP like 192.168.0.111 or something so you know they won't conflict--just make sure to hit the right IP of the router for the gateway.

Hi Ryoushin!

It seems that some folks are helping you out with your concern, but I am going to move this to our Technical Support area as our folks may be able to help out too.

Have a great afternoon!

Ok having looked everything over, again Raist I thank you for your help, and Jhanaka for the move to the right section of the forums, again I apologize for posting in the wrong section, this is what I have managed to diagnose...

My router is set to auto config dhcp and the only settings on the laptop are the same as the above for the wireless but the only changes ive done are setting the LAN on the laptop to the following :
ip 192.168.1.2
sub 255.255.255
gateway - blank
dns 192.168.1.1
and still have the same issue.
so im either missing something or not quite fully understanding. Sorry that my network tech degree isnt quite up to par. Must of slept thru that class /laugh

I used to have a wrt45g myself (currently a wrt610n), and find them generally very easy to setup.
First step is to confirm how it's connected, but that'll probably be ok already. Like RAIST above mentioned:

ISP modem -> Your Router (wrt45g) -> Wired or Wireless connection to all devices wanting to use the internet (PCs, Xbox360s, whatever)

Next step is to make sure NONE of the connected devices is setup to share it's internet connection (or setup as a DHCP server, but that's unlikely if you don't have internet sharing on).
Also make sure that all devices use the "obtain IP adress automatically (from DHCP)" setting in their network settings.

If your router was set to use "Automatic Configuration - DHCP" in Setup -> Basic Setup, it should work at this point. That is, provide all connected devices with a internet connection.

If it still doesn't work at this point, try powering down all connected devices and the router for a least 30 seconds or so.
And then turn them back on, one by one, starting with the router (wait for it to be fully started up).

Assuming you didn't change any (or much) of the router settings, it should all work a this point.
If you didn't change the router's default IP 192.168.1.1, all your devices should get a IP based on the order you started them up as from the router.
So:

Router wrt45g -> 192.168.1.1
1st device -> 192.168.1.2
2nd device -> 192.168.1.3
ect...

All these should be automatically given by the router at this point, and not be set manually.
On PC if you run ipconfig from commandline you should get something like this

Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : <your isp domain here>
IPv4 Address. . . . . . . . . . . : 192.168.1.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

If the default gateway is set to the IP if your router, it should work (assuming DNS settings aren't wrong somehow)

To check if something is wrong with your dns settings try going to http://74.125.79.99/ it should give the same as http://www.google.com/
In case of dns setting being wrong, it's usually a lot harder to fix.

But for now, try these
