View Full Version : I think I知 missing something simple here?

Hi everyone my name is Robert and I think I知 missing something simple here?

Here is what I am looking to achieve.
3 pc痴 lets call them
1) Main
2) Child-1
3) Child-2

Main = Internet access, sees both Child-1 and child-2
Child-1 = Internet access sees child-2, blocked to main
Child-2 = Internet access sees child-1, blocked to main

I want to access the Internet, and be able to retrieve or upload files to both Child 1 and 2, but I don稚 want Child 1 or 2 to have access to my machine in any way shape or form.

Set up Spec
Main = is a Window 2000 machine with all service packs (4) wired via RJ45 port of a (NEW) Belkin ADSL modem with built in wireless router (F5D7630UK4A)
Child-1 = is a Windows 98se machine this has never been on the net and has been used as a games (Sims) consul. This has recently been equipped with a Cnet CNWL-311 Wireless PCI Adapter.
Child-2 = is a Windows 98se machine this has never been on the net and has been used as a games (Sims) consul. This has recently been equipped with a Cnet CNWL-311 Wireless PCI Adapter

Here is what I have done so far.

(For here in all work has been on Child-1 I figured that once I had mastered Child-1, Child-2 would be copy procedure.

Main = has full Internet access, router set up no problem but unable to ping Child-1, unable to see child-1 on network. In fact unable to see network.
Child-1 can ping router, but that is it, shows no network at all when you try Internet access, it just cannot find any way of linking to router.

Hope this is not to long, and happy to comply with any requests, I am sure this is going to be an of course why did I not check that first scenario.

A Blood orange and a bag of nuts (well it痴 nearly Christmas) to anyone who help痴 me solve this problem

First, sounds like your client PCs aren't connecting or aren't getting a DHCP address from the Belkin. It is entirely possible that some neighbor ALSO has a wireless box and if you are both using the same default settings the PC's could actually be talking to the wrong box!

If you look through the Belkins manual you'll notice a way to change the channel of your system. I won't bore you with details, but I'd reccommend you switch to channel 1.

Next, you need to make sure your client PC's are seeing the wireless network. If they have a utility for measuring signal strength you may want to activate it and then verify they are actually seeing your router. If not, you will have to solve that problem first, perhaps with a larger antenna on the router or PC cards or a different wireless card. Once you verify you're actually seeing signal from the router at each PC you can move on to the next step.

We need to verify that your client PCs and the Belkin have the same SSID. An SSID is simply a name/and or number that identifies which WLAN you belong to. To make sure you're not using someone else's resources. It is possible the Belkin has a default SSID of something (ie "Belkin") and the PC cards have a default SSID of something else (ie: "Linksys"). THESE NEED TO MATCH OR THEY WILL NEVER TRY TO JOIN THE WLAN. It doesn't matter what they are, but they do need to match. So, once that's all matched up you should have good signal and should be able to see the WLAN. Not done yet though.

We need to make sure you're pulling an address. There are a couple of ways to do this. Go into the Belkins web interface and look for the DHCP clients list. It should have your main PC, plus whatever other PC's it sees and who it has given an address to. If not we need to figure out why not. You may have to verify that the client PC's are set up to search for an automatic address and remember to enable the client PC's TCP/IP interface.

I don't know what if any security you have turned on, but a good rule of thumb is to get everything connected and THEN lock it down. While everyone talks about WEP and WAP and so on, for most home users it's like being secured like a bank. You need some basic security, not Fort Knox. My reccommendation in this case would be to run with no security WHILE YOU SET THINGS UP ONLY! Then, once set up, I'd reccommend you use MAC Authentication Control to limit who can join the WLAN. The MAC address is the physical number of your cards. A serial number, if you will. By using specific MAC addresses to limit who may join, you are providing a strong first step in limiting intrusion. The truth is, for most people that's enough. There are so many UN-secured systems out there that hackers generally don't bother with anyone who has even a solid basic amount of security in place.
It's not foolproof, but it's a lock on the front door, if you will. It'll top 99+% of the intrusion attempts.

So you're up and linked and now you have some basic security.

As to the setup for file transfers, you can't create a network group and not let them see you. However you can keep them out of your files. The way you do this is to set up file sharing on their hard drives and yours using a password. Use a different password for your box and the same password for the two clients. This will allow you to access either, and they can access each other, but they cannot access yours (unless they acquire the password).

This is a basic outline of what you need to do. As you move through each step you may have more questions.

Hi Bouncer

Here is a copy of DHCP table?
IP Address Host Name MAC Address ROBERT 00-0C-6E-FF-20-2A CHRIS 00-08-A1-65-01-59

I have tried 1-13, which is the European channel settings, all fail

Link Quality 91%
Signal Strength 80%

SSID was set but have changed it to my own in case someone else was using that, but have checked no one else in street using wireless network.

All I want to do is to get CHRIS on line I will worry about the net work and security once he is on line.

I know that I missing something simple, Its just finding it.

Thanks for your help

Well he's pulled an address correctly.

Can you ping from CHRIS to the router?
(Edit: if Child1 = CHRIS then nevermind)

Have you gone into the Internet explorer settings and told it to use a LAN connection?

It really sounds like the IP connectivity is there, but the browser settings are not. Here's a way to verify this.

Open a command prompt on CHRIS and ping the following:


(that's speedguide.net)

If you get a response try to ping the site by name

ping www.speedguide.net (http://www.speedguide.net)

If you get a response then the problem is *probably* in your internet explorer settings. If not, then the problem most likely resides in the router, and we'll have to look a little deeper there.

It's a little tough to troubleshoot like this, so bear with any questions that seem obvious.
