Frontier just installed a new modem/router for us, with a 5g option. Basically I have my network name, then an option with my network name with 5g. Since I am not even close to being an expert with this stuff, and have never really had good internet. What is the difference? Also, why don't all my devices see the 5g version? The only one that does currently is my new Note 8. And finally, what can I do to get better quality internet in my whole home?
