Give up going to through ring doorbell in the bin!

I have had a ring doorbell for more than 12 months but 10 days ago it went offline. I have followed all of the Help instructions about 50 times to get it back up and running. By the way nothing except ring has changed everything works ! Rebooted my Wi-Fi twice, charged the ring battery. Held the Wi-Fi router next to the doorbell but nothing. It alternates between can’t find Ring Wi-Fi and the can’t join my network (that has not changed) ! I’m bored fed up think it’s a lie of … and put in the bin does anyone have any suggestions?
