I recently got internet through a local company (theres not many options for internet where I live), and they gave me an Arris Cable modem & router combo. Ever since I've had it, it will randomly lose connection throughout the day. Some days this happens only once or twice, and some days it can happen a hundred times a day, for anywhere between 1 and 30 minutes.
When it loses connection, the power light stays on, but the US, DS, and online lights go out occasionally. I've noticed sometimes only the online light goes out, while other times the online and either US or DS goes out, and sometimes all 3.
Unplugging the power and plugging it back in usually fixes it, but sometimes only for a minute or so before repeating the same thing. I called the technicians, and they came and replaced my box saying it may have been bad. It still lost connection even after this.
I'm not sure what to do about it, or what could be the problem. Any ideas
