Sounds good. Fir that other router you may need to reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If you donít know the router's default password, you can look it up HERE
You also need to reconfigure any security settings you had in place prior to the reset. Check out this site here
for video tutorials on how to properly configure your router's encryption and security settings. You may also need to consult with your Internet service provider to find out which DNS servers your network should be using.
