Wifi sync failed

Hi

On my second Fenix 6 Pro. The first one used to wifi sync without problems.

This one has always taken ages, you get the "this is taking long" message.

Yesterday it stopped altogether just get e red X sync failed.

Connection is fine just wont sync. removed and re added device no good.

I just did a full factory reset no good.

Tried disabling 5 g on the router .

I assume this is a hardware failure?
