|Just FYI, when a device suddenly stops working, that usually indicates a hardware failure.|
I'm curious what you mean by "worked a bit this morning"" Please explain.
Whatever is going on with your AP, it's definitely your AP that's the issue. Depending on what you mean by "working a bit" there are a couple things you can try to get it working properly.
1) Try recycling the power on the unit (ie: unplug the power for about 10 seconds and then plug it back in)
2) Check to ensure your AP has the most recent firmware installed on it
3) You could try resetting it to factory defaults and then reconfigure it.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
