Hi Rich - if it’s 4 years old then you’re well out of any Netgear or extended warranty, and consumer rights won’t be helpful here - 4 years is a good life and any longer is a plus. I’d enquire about repair costs but I’d be first tempted to try a factory reset and setup again from scratch. If the repair is too costly then I’d have a fiddle inside for any loose connectors as at that point you’ve got nothing to lose 🙂 Good luck!
