Hello, Right now our family has Charter internet. It's incredibly slow and expensive. We are using the modem provided by Charter, along with a very old AirPort Extreme (probably at least six or seven years old). We have an old AirPort Express to extend the WiFi in the house, but I have doubts about whether it is doing anything. We have a 2010 iMac that we use occasionally, but mostly use iPads and iPhones. We live in a 50 year old Cape Cod with three levels - basement, main level where the computer/modem/AirPort Extreme is, and upstairs where the bedrooms are. Next month we will be canceling Charter and switching to the fastest package from TDS Fiber, which should be significantly faster. I am willing to replace the AirPort Extreme and the AirPort Express and get something new. What would you suggest I buy? Would a new AirPort Extreme combined with new Airport Expresses be the best to pair with the 1 gig fiber? Do non-Apple WiFi routers work with Macs? If so, is there another one I should look at that would be able to handle a higher bandwidth? Thanks for any advice you have.
