Hello!

I am having a problem with a modem, apparently, that has worked well for around 3 years. The present problem is that it disconnects me at around 11 pm every night (thought not precisely, and it changes) and remains disconnected with the power light flashing red to green to red (with the ethernet flashing green at the same time). It will not reconnect by itself, but will when I push the on/off button---only to disconnect again repeatedly at different intervals.

This happens every night, but only around the 11 pm mark. It's fine from the morning to around that time.

What could possibly be the problem? My ISP says there has been no service disruption at this time.

Thanks for any help or ideas. Up til now, I have reset the modem and another computer hardwired into the same modem. The problem continues.

I suspect a defect in the modem/router or, more likely, in your electrical system. Maybe temperature related; maybe more electrical load at night.

I thought it might have something to do with the router, so I unplugged the wires and have been using the modem only.

By temperature problem do you mean the modem itself may be overheating? And by electrical do you mean my power bar or the electrical system of my house? Up until last week, everything worked fine. The modem has been problem-free for 3 years. Is there a way of knowing for sure that it is overheating/an electrical issue without replacing the modem just yet?

That is a possibility, but since the problem occurs at night I was thinking of the opposite--something (connection, wire, ...) being colder, hence contracting and not working properly.

And by electrical do you mean my power bar or the electrical system of my house?
Yes, any of the above.

I can't think of many. Certainly if you are using a surge protector or power strip try plugging the Speedtouch modem/router directly into a wall outlet. Look for any nighttime additional electrical load (e.g., furnace, electric heater).

Up until last week, everything worked fine.
Can you think of anything that happened around that time (e..g., weather got significantly colder; broken basement window; somebody got a new electric blanket)?

Well, I plugged it into the wall and the problem remains, so the problem isn't the power bar. There have been no new electrical devices running lately. And the temperature has never caused anything like this, either. So I am at a loss. But thanks again.
