Proper router and software setup.

By coyyai ·
A while back I bought a Linksys router because a router is supposed to have a built in firewall. I have not been able to properly setup either the router or my OS (ME) or other programs to utilize the built in firewall technology that the router issupposed to provide.

I know my cable internet provides my location with an IP address. The router then assigns IP addresses to the other three computers in the house. After that I am lost.

Do I take the IP addresses assigned by the router and enter that address into specific fields on each computer?

Do I have to enter it multiple times in every software application that accesses the internet?

I heard when you have a properly setup router, firewall and software, it will eliminate most of the popup ads because the cookies that get implanted on your hard drive can not communicate back to the ad source computer. Is this true?

Is there a place on the net where it will shows me what the fields in the OS mean and do? I understand things much better if I know their function and how they work.

What other information should I be aware of in the proper setup of my router?


Thanks for any help you tech wizards can provide.

Proper router and software setup.

by quintar51 In reply to Proper router and softwar ...

here are some tips:

First, the router should come with a pre-configured IP address, so you can manage it using internet explorer. Usually, it's something like 192.168.x.x.

Once you log in, you should see the different options you can configure. You should setup your internet connection here. The router makes the connection, and then all other machines connected to the router, will use that connection IF you instruct them to.

There should be a status field, letting you know if yourrouter is connected to the internet or not. Once it is, you then have 2 choices.

right-click network neighbourhood, properties, go to tcp/ip for your network adapter. In the IP Configuration tab, you can either choose to obtain IP address automatically, which means if your router has DHCP enabled, which it should by default, then the computer will get all necessary information from the router automatically.

If you need to use static IP addresses on your machines, then you need to configure a gateway for each. The gateway will be the IP address of the router.

After that, you should be able to connect no problem. also, the firewall is enabled by default, meaning, you might need to configure ports to allow certain programs to work.

Not all programs will work, cause the way this whole setup works is through Network Address Translation. You get one IP from your cable provider, and all internal machines use that same IP out on the internet. Some applications don't support this setup, ie msn messenger, and etc.

Good info but did not really help; Looking for proof the firewall was working. I already found it at, and you can test yours at

To build on the previous answer with more specifics ...

At home, I have 3 computer connected via a Linksys DSL/Cable Router which is connected via DSL to the Internet.

Setup ...

Router is assigned the IP address from my DSL ISP provider everytime I dialup (which is once every few months) x.x.x.x ... then the router is assigned the IP address of 192.168.1.1 (default) ... the computers all have IP address within the 192.168.1.(2-255) range ... therefore on computer #1 in the TCP/IP property setting for the NIC I have ...

gateway IP: 192.168.1.1
subnet mask: 255.255.255.0
NIC IP: 192.168.1.2

That's it for adjusting any setting on the PC

Now, on the router, as mentioned about the firewall, it is enabled by default as mentioned in the previous answer. There should be a screen where you can choose which ports can be accessed through the router (the basic ones like PPP, SMTP, POP3, FTP, etc) are already open (which means most programs should work without any worry).

As far as DHCP goes, it does make life a little easier, but not for setting up 1 or 2 computers and if you aren't really familiar with it. Besides, most people like to know exactly what is going on.

On a final note, I've never had any trouble with MSN messenger working through my router (1.5 years).

Hope this helps.

Just a quick note about Quintar51's answer.

Follow all of his steps, but in setting up the router, some of them need to have the DHCP server turned on in the router.

There should be a DHCP tab once you have accessed the router through it's IPaddress. Just ensure that this is enabled.

Your router set up the IP as stated in the responses given. You should not have to set up any IP's they are assigned. Use the instruction that came with your router or go to the Lynksys web site to get the correct configuration. I understand yourdelima because I have just set one up myself and I am running just fine. It took a little time to get it set up like I wanted it. Even in Techrepublic there should be some documention on routers. You should have set up your router with the software that came with it.
