Limited or no connect

Try switching router off, wait 1min and switch back on usually restores everything provided it worked before. You do not mention what was being done before it "stopped" working.

Hi i'm Rain.
Limited or no connectivty means that your router is not picking up the connection or it is connecting but may have something blocking the connection.
To repair this you will need to reinstall the routers drivers to your computer. You should have a disk that came with the router. Use the disk to reinstall the needed drivers to connect to the internet.
If you do not have the disk , the easiest way is to call whom ever you got the router from and have them bring the disk out or go pick the disk up. Always remember when you have a router installed by a company the disk belongs to you. Most times the technician will not give you the disk because that way you will have to call them to come out to reinstall it. Thats more money outta your pocket.
