Think its internet related, my router is 5 + years old, its ASUS RT-AC88U when we got it Cnet called it " The Lexus of wireless routers " cost us $225.00 that being said we got it cause it had 8 Gigabit LAN ports, I wired my house with CAT 6 Cable, my trading office has 6 CAT Jacks So I can rearrange my room as I see fit, rest of house has four CAT 6 jacks around the house, only use the wifi for the cellphone, still running strong and still for sale at amazon for $200 bucks.. We invested in a good Router and its last and well worth is. Also it can handle TWO WAN connections if I have need for a 2nd back up internet connection as well.
