Hello. I know the 100 is no longer supported, but it has worked fine for my family. That is until seven days ago.
Every 24 hours I get the flashing red light and cannot make calls. If I unplug power from the device, plug it back in, everything works in about four seconds.
What is causing this? Do I need to upgrade to a new Obi?
By "every 24 hours" do you mean that the fault occurs at the same time every day or that the reboot fix is only effective for 24 hours?
When the LED is flashing red do you still get dial tone? If yes, dial ***1 and report here what you hear.
