Green light on modem stays on, no internet, speed test zero
Lose my internet on all devices, ethernet and wifi, several times a day. If I wait it will usually come back up on its own but can take up to an hour. Sometime takes several reboots of modem to get internet back up. I can speed test on wired and wifi devices and get a zero. All lights on modem remain green.
I have had 6 ATT repairmen here since New Years Eve. Everyone tells me my line tests fine. The last guy told me they have tested, replaced and fixed everything that could possibly be wrong with my internet and if I call for another repairman I will be charged.
I had two computers connected to the modem by ethernet, three iPads and two android phones on wifi. The last tech support guy told me to unhook the ethernet, and run everything wifi. He said something in my house is causing the modem to lose it's sync. Interference of some kind. He said turn all the devices off and bring them up one at a time. I had an outage with just one of the iPads on.
Would a power conditioner for the modem correct this?
If I finally give up and switch to the cable company for my iSP will that correct my issue? I switched from CompuServe to ATT dial up over 20 years ago. One of the first in my neighborhood to get DSL from ATT. Would prefer to have a solution that keeps me with ATT.

My wife’s Samsung Note 9 would cause the IP on the modem to fail disconnecting all devices. When I figured this out I spoke to ATT. He said to ch ck with Samsung. They told me to reset the network settings on the Samsung Note 9. Seems to have corrected this issue.

Hello @ClayPotts,
I don’t think a power conditioner for the router will correct this, unless the router is plugged into a power outlet that’s faulty.
What electrical equipment do you have near the router?
Also, is there a specific time these issues occur?
My thinking is, it could be something electrical causing interference with the router at a specific time of day.
Please let us know.

The router sat next to a computer.
There is no pattern to it shutting down. I moved the router this morning to a different outlet with nothing else plugged into it. So far so good.

Hello @ClayPotts,
Please leave the router plugged in the different outlet for at least 24 hours. If you have no issues, I think it would be safe to assume it could be the outlet.
Please let us know what happens after 24 hours.

I only had to restart the modem once in a 36 hour period. Major improvement. Am going to try a different part of the room this morning. Trying to get it as far away as possible from any possible sources of electromagnetism.

I made it 36 hours with out an outage. This morning I had to restart the modem 4 times in one hour period. Any chance my wife’s Samsung 9 is the culprit? Outages only happen when she is home. phone was in the room this morning when the modem kept losing sync. No issues since I moved phone to different room.
