How to change router setting.?

we just got a wireless router awhile back and i wanted to set it up so no one could connect to our network via WI FI, the default setting was set on WEP (Wired Equivalent Privacy), and i wanted to put it on WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) with a password of my choice, the router and modem are both down in my basement, and the wireless adaptor is upstairs on our 2nd pc, but when i put it on the WPA-PSK setting i had internet down here still but not upstairs, my question is how can i put it on that setting so no one can get on my network and still get my connection upstairs?How to change router setting.?
1. Connect your computer to one of the LAN ports on the router. (or Wirelessly)

2. Open your web browser and type in 192.168.1.1. Press Enter

3.If it asks you for login information it is the following:

NETGEAR ROUTERS:

Login: admin

Password: password



LINKSYS ROUTERS

Login: admin

Password: admin



4. Click on Wireless Settings



5. Select the WPA-PSK option. And Enter a passphrase. Make it something you can easily remember, but it hard for someone else to guess. It should be between 8 - 63 characters. (BobTheBuilderIsGreatFun would be a great passphrase for instance!)



6.Make sure you hit Apply



7. Restart ALL computers you are connecting to the router.



If the computer is WIRED:



1. Plug it into the Network Interface Card in the back of the PC first, then the LAN interface on the back of the router.



2. Repeat the Same with all PC's connecting with Ethernet wire.



3. Boot the PC.



4. Go to your Network Connection Center, and try to connect to the network.You should be prompted for a passphrase or WPA Key. Just be sure you type it EXACTLY how you set it up in the router.



Bingo! you should be connected AND secure! :-)How to change router setting.?
Your up stairs computer is still trying to connect to it via WEP and its not reconizing it. Scan for a new network, click the network and then push WPA instead of WEP and try that. If its not working go to control panel-network connections and delete the wireless one named after your network and try again. (I believe you open network settings, right click wifi connection, then properties i could be wrong)



Also be sure your SSID broadcast is on, otherwise you have to maneully input the network name while you set up. I suggest you turn it off when you get things going though, makes it so its hard to find. You can also turn on MAC adress filtering if you feel the need to but it gets a bit complicated to explain.
