I lose my internet connection at least 4x a day. (Can't connect with multiple devices) In addition, when watching ROKU, we will suddenly lose signal. Sometimes it comes back on its own. Other times I have to go up to the attic and reset the modem. I've noticed that the US/DS light is usually blinking when I do this and the 'online' light is not on.
We live in a new house, with new wiring, nothing is spliced, etc. I'm thinking it might just be a bad modem. The guy who installed our cable, installed the modem, as well. It's an Xfinity echnicolor tc8305c. Our speed is 25/5. I ran a test on it this morning.
Any help would be appreciated.
