Access your router Setup page 
Open internet explorer go to http://192.168.1.1 (default) username: admin (default) password: "leave it blank" (default)
Go to Security go to Filter
if you know that Ipaddress of the computer you want to block for example 192.168.1.10
You can create up to five different IP Address Range filters   Users who have  filtered  IP addresses will not be able  to  access the  Internet at all   If you only want to filter one  IP  address instead of a range of IP addresses, enter the same  value into both fields  For instance, if you wish to filter the  PC with  the  IP  address of 192 168 1 5, enter 5  into both  fields on one line: 192 168 1 5 ~ 192 168 1 5 

if you know the MAC address of the computer click the Edit MAC Filter Setting and input the MAC address you want to block. 
blocking by MAC address is the most effective solution to block a computer... while blocking by ip address will be easily bypass by changing the ip add of the pc

then saved your settings and reboot..

You're asking for a schematic for a router. I doubt that the manufacturer will have one for a consumer "throw away" device. Most simple electronics like routers < $100 items now are considered throw away. I supervised one of the largest electronics service shops in the Denver area and even for us, some schematics were tough to get unless you were an authorized service center. Sorry

Wireless router installation

its authentication number. which you will get from cable tv operator. its not pin inside your router.

If you are trying to connect to an app at that IP address then you want to enter it like so: 192.168.1.10:5800

Connect a Ethernet cable from your PC directly to the router and try to open the page 192.168.1.1 with "admin" as user and password.

Hello =) Are you trying to access the routers dashboard? If so, have you tried the default password? The default password is "admin". Leave the username field blank. Router default IP should be 192.168.1.1 but it might vary.Hope this helps! :)

Log in to your NETGEAR router by browsing to http://www.routerlogin.net/ or http://www.routerlogin.com./ Enter the username (admin) and password. By default, the password is password or 1234 unless it has already been changed. If you cannot log into your router: Unfortunately, there is no way to recover a lost or forgotten password from a router or access point; you will need to reset the device to factory defaults. However, once the device is reset to factory defaults, you can use the default username ("admin") and password (either "password" or "1234" depending on your router) to reconfigure your router settings. If it is not visible, you can change your wireless passphrase; however, changing the passphrase will cause you to lose your wireless connection. Connect your computer to the router with an Ethernet cable before entering a new passphrase into the text box and Clicking Apply. If there is a small hole in the front or back of the router push a hair pin in to reset to factory settings.

To connect to your wireless router, the router's wireless settings needs to be configured with the SSID, encryption etc. and also the wireless cards in all the laptops/computers needs to be configured with these router's wireless settings. Then the laptops/desktop computers can communicate with your wireless router. Connect a LAN cable from the Linksys to the LAN port on your computer. Open a browser and enter the Linksys configuration URL http://192.168.1.1 The default login = admin The default PW = admin You can protect your router by changing the default admin PW (write it down and put it in a safe place) Go to the wireless configuration and set up the SSID and WPA or WPA2 encryption to protect your wireless network and Internet from unauthorized access. Now apply these settings to the wireless card in your laptop/computer.

Under applications and gaming, you will want to select upnp forwarding and then you can enter whatever custom application you want to be allowed in or out.Upnp can also be set automatically from the Administration menu.
You will need to know which ports to use, usually you can get these from the software developer, such as bungie. You can also use the application name, but I find the numbers easier to work with.
