How come wi-fi is not working but says I got signal
Sometimes routers have this issue. You may want to reset your router by putting a pen into the reset button if your router has one. If this does not work, you may need to call the manufacturer and see if it's defective.
I have tried that before and had to call support to get it to work, I found out if you unplug your router(s) and after 30 seconds plugging them back in the connection stays for about a day
