YA’LL.... the stuff I went though for it to finally work.
I did everything everyone said above and NONE of it worked until this:
Reset everything — your watch, your phone AND your modem for your internet. It doesn’t matter how your phone is reset (either hard or shut down via settings). Reset your router/modem, when it pops back up after the reset, click “forget network” (settings wifi click the “i” with the circle around it and then click “forget network”), enter your password and try it again.
Hope it works for you!
