My sister's stay-at-home job provided her with a computer that must have a wired connection. They supplied a modem. She pays for the Internet. She now wants to be able to access wifi so she can use laptops/phones. I figured she needed a router so I bought her the belkin g54/n150. I tried to set it up but I discovered that she does not have administrator privileges to go in and change network settings. After playing around changing up cords, I got it so her desktop computer connected fine, the wifi network was found and paired on the laptops and phones, but still had no internet. No idea how to fix. Any help?
