A reader wants to know what happens if you switch routers. “When the cable company changes your router modem-combo., Do you have to change anything in your computer?”
You will have to make sure that your PC is connected to the network generated by your router. The cable company may have a tech come out and set that up for you.
If not, you’ll have to set up the router on your PC and change the router’s default password to a secure password that’s known only to you. The cable company should provide the necessary instructions for you. If they don’t, you should call their customer service number and find someone to talk you through it.
