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.
