Are all computers capable of having Fiber Optic internet? If not, how do I know if my computer is?

Fiber Optic is merely a different way to deliver internet to your home. You can get internet through satellite or a cable company or like I do from a tower broadcasting a WIFi signal. You can also get internet through 5G or cell phone frequency. Remember when we used to get our internet through the phone with all it beeping and buzzing! Fiber optic is probably the best quality internet you can get. I'd kill for it out here in the country! They lay the fiber optic cables along the street and then run the connections to your house. Your computer doesn't care WHERE you get your internet is the good news!

So, my computer doesn't need any special part for me to get Fiber internet? That's what I want to know. As far as I know, I'm only good to go with an Ethernet connection. I don't know how fiber works.

I second Draclvr here. The computer doesn't care and won't need any new parts. On the other hand the fiber needs to be connected to some new little box somewhere in your house. Then typically you just plug in your ethernet cable in that box. A bit like the old phone modems but without the beeping and buzzing. Those boxes usually also offer WiFi connection as an extra option but that's not necessary to use.

Our area got fiberoptic cable internet a few years ago and it is overall faster and more stable. I never thought this kind of internet would be possible out here in the sticks, so it is a very pleasant surprise.

As Fogfighter says, you should be able to use your ethernet cable just like you do now. And if you want to go WiFi and your current computer does not have a WiFi adapter, you can just buy a USB adapter and plug it in. The adapter I built into this computer stopped working, so I got a USB adapter for about $50 and have been using it for a couple of years now.

Yup, fiber optic is the gold standard right now. I'd love to have it out here!

Okay, good to know the ethernet connection is all I need on my computer. I sure hope they don't have to do much in the house, especially hope they don't have to access my phone box as I'm not sure if they will be able to. They will change my phone out also from what I understand. I haven't actually talked to anyone yet. They've sent information but basically said it was optional but pretty much needed to be done. Now, all of a sudden, they are telling my they will cut me off completely on or around January 5th of next year. This is the first they are saying it HAS to be done or I have to change carriers.

Thank you!
