I have used both the router and ONU for about 2 years. Even though they are old, they are very good routers, no problems at all. You can run the net as much as you want to check. I installed a mini UPS for the router. The UPS has a 9-volt port and a 12-volt port, but since both my router and ONU are 12-volt, I couldn't run them with the UPS, so I had to buy a 9-volt router, which is why I am selling this.
