Considering how many wifi access points there are, for example each time one goes to a cafe, airport etc. it’s much safer to assume that the wifi access points aren’t patched and to ensure your devices are patched instead.
Any Apple stuff (laptops, phones, tablets) already have patches in beta versions of MacOS or iOS so should be available very soon. Using a VPN is also useful, although I rarely bother. Any https sites (such as online banking, or even many simple websites nowadays such as this very forum) are still encrypted.
