This started about 3-4 months ago. Randomly, usually once a week, all our devices would lose internet connection. We would check the router and lights still show that it's working and that it's receiving and sending just fine. One time when this happened, I tried unplugging the DSL cable to see if it changes any of the lights, but nothing happened. When I unplugged the DSL cable, the lights still showed that the DSL cable was plugged in and that everything was working. There doesn't appear to be any straight-forward cause; it happens regardless of the time, or the amount of people connected. A couple times when this has happened, I just tried to wait it out and see if it fixes itself over time, but after 4ish hours it still is not working. The only fix we've found is to restart it, but it seems to only be a temporary solution. The only thing I've checked is if there was a firmware update, but our router is currently on V1.0.1.74_1.0.1, and I think that's the most recent version. We've had this router for a little over 4 years, so I'm not sure if we just need to buy a new one or if this is a common issue and I'm just missing something? When it comes to routers and networking, I'm not as savvy about it, so any help or advice would be greatly appreciated.
