Plug the power cord into the router and plug a cat5 ethernet cord into on of the four LAN switch ports on the router (and not the WAN port). Plug the other end into the PC.

On windows
Start–>Run
cmd
ipconfig /all

write down the IP address of the Default Gateway on your Local Area Network Adapter.

Open your web browser and type http://{IP address of Default Gateway}
ie http://192.168.0.1

The Web Administration Username and Password should be
Username: admin and the Password should be left blank by default.

Enable the DHCP server on the router. Save the settings.

Now enable the Wireless radio and give it a name (SSID) and use encryption (64-Bit WEP is sufficient). Give it a 5 character password and REMEMBER IT (make it easy to remember like the first 5 digits or your phone number or your street address). Save the settings and the router should reboot.

Now plug the WAN the cat5 cable into the modem and then other end into the router’s WAN port. Cycle the power on the router.

Wait about 30 seconds.
Go to the laptop of WiFi desktop and enable the WiFi connection and scan for WiFi networks. Connect to your (the SSID you entered) then type in the password and you should be good.

You can always use a cat5 ethernet cable and plug it into one of the 4 switch ports on the router to get a more reliable connection.

Linksys has some pretty basic NAT controls and firewall setup included with it, but if you’re looking at heavy server protection it just isn’t there.

to configure the firewall just launch the web interface of the router in a connected computer
usually http://192.168.x.x by default, but it varies

Other than that, it’s always going to be either strict or moderate, depending on how many ports you open. Strict nat is necessary as you only have one external IP.

Routers (wired or wireless) are like mini-PC to allow several PC’s to connect to a single Internet connection. Trying to connect two wireless together is a headache you will want to avoid. Especially if one or both goes down.

The N Router should be able to handle the extended distance without added equipment. That was the whole point of introducing the N Wireless. For larger houses and small business that have more floor space than a regular wireless could handle in range.

What you really need: a WAP (Wireless Access Point). WAPs are used to extend a wireless network further. These act like repeaters you see on Radio Towers. They capture the signal and pass it to the next point. Most Office building that support Wireless use WAPs.

–BEFORE DOING ANYTHING TURN OFF THE COMPUTER–

To do this you are going to have to remove the access panel on your PC. It should just be a couple of screws. Once that is off, you will have to look in and you will see where the other things you looked at earlier are, and there should be an empty slot or 2 there that your new card will fit.

Towards the back of that slot on the PC itself there will be a cover plate that needs to be removed where your antenna will go through the case. It will have one screw in the top of it. remove that plate, and slide your adapter into the slot. then return that screw to the hole to hold it securely in place. No need to make it too tight, just snug.

replace your cover and you are ready to set up the software.

If you feel the least bit uncertain about any of that take it to best buy or somewhere and they can do it for you….for a fee of course.

if you have already tried all that and really do have no more open, you could always remove your modem card and plug it in there as long as all that’s on it is the modem. You won’t be using that anyway.
