I have setup my Rpi 3 as wifi access point and it was working for a long time. But some day, wifi stop working unexpectedly and i was no idea that what was the problem. It means wifi access point is showing on my lap and phone , but i am unable to connect to it.
I have not done anything to the configuration file and configuration was done by referring official documentation.
When i have this problem, I restarted the Rpi and I tried to connect my lap to the AP and it was worked at that time.
What will be the reason for frozen wifi AP? The problem solved by restarting it, but i want to know the reason?
Could you please help me?
