Let me start out by saying I am totally and completely not a computer geek. I don't speek the language of the tekkies.
I have an HP laptop and out of the blue, it will just not connect to the internet wirelessly. It will say connected but no internet access. This happens and random times, at least once a week, and for exactly 24 hours between 1 a.m. one day to 1 a.m. the next day. I can connect via ethernet cable just fine. My phone and TV can connect wirelessly, but not my internet.
My signal strength is usually excellent when this happens, so it's not that I'm too far away from the router.
I have tried resetting my router/modem multiple times when this has happened to no avail. I have factory restored my computer. I have deleted my driver
and reinstalled it. Literally the only thing that has worked thus far is connecting to an ethernet cable. I called my ISP and they said my router is fine and nothing is wrong with it.
Before you ask, NO, I don't have any monitoring software or any software that prevents the use of internet after a certain time. Keep in mind that my computer is totally factory resetored, totally clean, nothing on it but what it came with.
