Starting a few days ago, my modem gets stuck on the send light(blinking). Resetting the modem does nothing. After a while, the modem restarts itself and remains stuck on the send light. I'm not sure if it's the ISP or modem. When I called, they mentioned nothing about the internet being down in my area. Yesterday, it passed the send light after about 48 hours of blinking, but it got back to its usual state when I woke up this morning. When I got home, the send light blinked for another three hours until it reached the online light. After it came online, the connection was dropped for about 30 seconds before coming back up.
My modem is about eight and a half years old. Does anyone have any information or resolutions regarding this problem? Also, would the problem be my modem or ISP?
