I just moved into my parents house. I had previously set up an older wireless G router there. I have a new wireless N router that I was using at my own place that I want to install at my parents house. Can I just swap the units and leave everything else the same? If I do, is the network key the one from the old router or the new router?How do install my existing wireless N router on a new Network with pre-existing router?
It depends on the type and brand of routers, but some routers will allow you to change the mode from ';gateway'; to ';router';... An additional router behind the main router would have to be in ';router'; mode, and even then you would have to add some static routes to get everything working.
My suggestion would be to replace the orignial router with the new one, and leave the older one out of the network...How do install my existing wireless N router on a new Network with pre-existing router?
You can swap them, the network key will differ between routers.
you'll have to install the n router as if it's new, but it will retain the settings you had when you didn't live there. the network key will be that of the new one.

Router Can Never Redirect a Connection From Outside World to Inside World Unless it Sees an Open Port - Right?
Assume i send a request to a server from my PC behind a router. Web server will response, the response will hit my router first. Then how come my router will redirect this response to my PC since i do not have an open port set on router for the out going web browser connection?Router Can Never Redirect a Connection From Outside World to Inside World Unless it Sees an Open Port - Right?
The router automatically opens the necessary ports dynamically in response to an established session. Most routers use Network Address Translation. When you hit a site outside of your network, NAT keeps a record of your machine's IP address and the outgoing session. When it receives a response from the web server it opens the ports as necessary and forwards the packets to your machine.
This is an over-simplified explanation of the process. Port pair assignments are taken care of during the TCP/IP handshake. Once a port is opened dynamically the router will only accept traffic on that port from the source IP of the destination and only if the packet sequence numbers match up properly.Router Can Never Redirect a Connection From Outside World to Inside World Unless it Sees an Open Port - Right?

You need to re-phrase your questions and provide more information.
Because the web browser makes the connection. After that data can go both ways. The web server isn't trying to make a new connection. It is just replying using the existing connection.
Some ports are static, like mail, UDP, and a few others
(see link below for a list of 'common ports').
Of the other 65,535 odd ports, the router sends outbound requests through established ports, then listens on a port for the reply, then relays the packets to the MAC of the proper machine from it's address table.
Unrequested packets, going to the wrong port, are dropped.

Port 80 handles outgoing Internet requests.
';This is the primary port used by the world wide web (www) system. Web servers open this port then listen for incoming connections from web browsers. Similarly, when a web browser is given a remote address (like grc.com or amazon.com), it assumes that a remote web server will be listening for connections on port 80 at that location.';
Your header will describe (among several things) what port and what machine on your local network sent the request %26amp; the reply will have a header with this same info (as it's destination).

Can I plug my wireless router into the back of my computers ethernet port to share the Internet?
And how do i configure my computer to do so. And also my wireless router is a Netgear WGR614.Can I plug my wireless router into the back of my computers ethernet port to share the Internet?
That's how it works, YES.
However, you have to understand the order of the connections..
The MODEM gets plugged into the back of the router FIRST, into the slot marked INTERNET on the back of the router.
Then, you just run the cable that came with the router from any one of the other 4 slots on the back of the router directly to your computers
network card.
Then just run the software that came with the router from the computer the router is physically attached to.
Its pretty simple. Then, depending on whether you have a wireless router or wired router, you will set up a wireless network name an so forth.
If you are just using a wired setup, you will simply run another cable from one of the three remaining slots to your other computer.
Just remember.....the MODEM gets plugged into the slot marked INTERNET on the back of the router, and the other things such as computers, network printers and so forth go into the other slots on the back of the router.Can I plug my wireless router into the back of my computers ethernet port to share the Internet?
Connect the cable/dsl modem to the router's WAN port(sometimes named as Modem Port, internet port, Up-link port).
Then connect the router's LAN port to the computer.
Then turn off everything.
Turn on cable/dsl modem, wait few minutes until most lights show up.
Turn on the router, wait few minutes until most lights show up.
Turn on the PC.
The router will have both wired and wireless. It's all about connecting the cables properly. There should be a wan or Internet port on the back of the router. Connect that to your modem. The port will be a port further away from the other ports. The other ports that are closer together than the one far apart will connect to the computers. That's it, it's all plug and play.
Instead of wireless, I highly recommend this: http://www.youtube.com/watch?v=o9KWdOLgy

How do I connect xbox to internet through router?
I have bought a second hand xbox and ethernet cable. I have Virgin broadband through a router, and currently my laptop is connected to it via USB cable. We have plugged in the ethernet cable to xbox and router, but when it starts trying to connect, it says there's an error with the IP address? Help!How do I connect xbox to internet through router?
First thing you want to do is go into your dash to network settings and set everything to auto configure. Then shut off your box. (assuming your still plugged in to the router) Turn off the router and wait a few minutes. Turn it back on. Turn on your xbox. Then go in to network and test connection. It should go right through at this point. If it doesn't then you will need to open your gaming ports on the router. First call microsoft(18004myxbox) once you get a live person ask them what ports you have to open on your router(they will ask you which kind you have) then they will tell you. Next you have to call customer service for the router and tell them what you need to do. they will walk you through it(it's pretty easy to do right from your comp) then just reset your xbox and you should be good. It can be kinda a pain but I had to do it to mine and it works great now.How do I connect xbox to internet through router?
what sort of router? and it should work. probably you need to open the port. email me for help or preferably you should post this message on the xbox forum or contact xbox

How do I connect to my router?
I have a Airlink101 N Router model #ar670w. My router is shown as hidden. Someone else set up my network. How would I work around the fact that my network is hidden and connect to my router via wi-fi. I need to connect my iphone and laptop to the router.How do I connect to my router?
there should be an option to connect to a non broadcasting network you will need to click that if he didn't set up your computers to the network you will need the wep key as wellHow do I connect to my router?
first click start%26gt;run%26gt; type in ';cmd'; (no quotes)
a black box opens up
type ipconfig /all
look in the list for the gateway address
take this number (usually something like 192.168.xxx.xxx) and put into web browser (hit enter)
this will take you to your router setup page, it may need a password
if no password you want to turn on SSID (make sure you apply once change is made)
you should see your network then
normally you can change it from hidden to free by just looking at the router setup book which came with your router and there it will tell you the website so you can change your settings =]

How do I setup a router to login to our internet connection?
We have one internet connection and two laptops that require internet. Normally we can only use one laptop at a time on the internet, our line requires a login and password, and only one session at a time. I have a wireless router that I'm told I can setup to be logged into the connection, store the login and password in? How do I do that? Any more information, clarification, walk throughs, whatever, is much appreciated.How do I setup a router to login to our internet connection?
Every router is a little bit different, it would be helpful to know what kind of router you have, or at least the brand. I would also help to know the name of your Internet service provider, since they all do things a little bit differently. You ISP can probably help you better than I can, but here's a couple of things you can try:
On the basic setup of your router, you should be able to select a connection type. It sounds like yours is PPPoE or maybe L2TP. With either of those selections, you should be able to enter in a user name and password.

What is a wireless router and how does it work?
Just recently, my sister ordered a DSL internet service package from a telephone company and she just mentioned to me about getting a wireless router. Would something like that be required for DSL? I also wanted to know what it does. Please explain it to me in great detail. Any answer is very much appreciated.What is a wireless router and how does it work?
';Would something like that be required for DSL?';
This would depend on the device that the Internet service provider (or telephone co.) sends out to you. For example, Verizon offers a modem/wireless router combo..this means that a separate wireless router is generally not necessary.
If the modem that the Internet service provider sends out does not have wireless capability, then you could pick one up for pretty cheap. Here is an exmaple:
