How old is your router?
It's only 2 or 3 years old. I got it to work with fiber optic internet I switched to then.
It works great for a wired connection to my Dell PC, and for WiFi TV, it's just that the Magic Jack VoIP phone incoming calls don't seem to work all the time. I disabled my voicemail again last night, and today I can call my phone from an outside line. So for all I know, this might work if I want to do without voicemail.
I spoke to a guy at Office Depot today and he recommends a NetGear Nigththawk AX2400 that costs about $180.
I'm looking at devices on Amazon right now for VoIP routers and some of them are around $50.
I was wondering if there's a small device I might be able to run solely for the VoIP phone and keep running the AC750 for Wifi TV and wired internet.
I guess I better wait a while longer and see if I can receive calls every day with my current settings.
