For this walk through, you will need a computer that is hard-wired (connected using an Ethernet cable) to your router. If you are on a wireless computer, you cannot connect to the router without knowing the password. If you do not have an Ethernet cable, you can either purchase one at any office supply center, otherwise, you will have to reset the router, and enter your configuration information for your connection again. This walk through also assumes that the router's default IP address and administration user name and password are at defaults. If you have changed either of these, you will be unable to log into the router using this walk through and you will have to reset the router, and enter your configuration information for your connection again.


  • First, open Internet Explorer or your preferred Internet browser.
  • Next, you will need to log in to the router. To do this, go to the address bar at the top of the page (the long white bar across the top of the screen which will contain the web address of whatever your home page is) and empty it by backspacing all text out of it.
  • Enter the router's IP address, which is by default set to Then press enter.
  • If everything is otherwise set up correctly, the browser should prompt you for a user name and a password. By default, for Linksys routers, the user name is to be left blank (do not type anything in) and the password is admin. Once you have that entered, press Enter on your keyboard, or click the OK button.
  • If the user name and password are accepted, the browser will load a Linksys Basic Settings page. If the user name and password are not accepted, the user name and password have been changed. If you do not know this information, you will have to reset the router.
  • One of the first items on this page should be for your Internet Connection Type, this will probably be defaulted to Automatic Configuration-DHCP, change this to Static IP.
  • This will reveal a series of boxes beneath the Internet Connection Type asking for Internet IP Address, Subnet Mask, Gateway, DNS1, DNS2, and DNS3. If there are numbers in these boxes, they need to be changed to match those specific to your account. Enter the corresponding information in each indicated box using the information that the installer left with you after the installation. If you have lost this information, please contact our technical support.


The subnet mask for common regular residential and premium residential accounts is, and the default gateway is the same as your IP address, except the last set is going to be a 1. (ie. 172.16.xxx.1).TISD’s DNS Servers are and, we do not have a third DNS server, so you can leave those boxes set to

Businesses or residential accounts with a public IP address have different subnet mask settings and gateways.

This will restart the router and may give you a screen that says Settings are successful or Your configuration changes have been set. Press Continue if you are given the option to.. When complete, it will return you to the page you were just on.
  • Once you see the page you were just on, you can now close this window.
  • Open an Internet Explorer or other preferred browser window, and if the configuration was successful, the browser should load your home page.


If you are concerned about neighbors or other people having access to your network, you can set up a security key on the router. Return to the Router Configuration page to see how to enable WPS or WPA encryption on your wireless router.
