Do I need 5G router?
Since the changeover to 5G in our area our AT&T wireless internet speeds have decreased by 2/3 or better; from 30+ mbps to under 10. Occasionally we get 0 mbps upload speed! We have a 4G router (IFWA40). Should we invest in a new 5G router to solve this problem or is this just AT&T slowing down our network? I am getting -100dBm signal strength also. Maybe this is the issue? TIA for any help anyone can suggest.
