That is like saying a 12 year old should be able to be healed from being quadriplegic because they are still growing. Some medical conditions are for live (at our current medical knowledge) and it doesn’t matter if they are “physical” or “mental”.
Client isolation doesn’t help. That is just the access point not routing traffic between connected devices. The problem with WiFi is it is a radio signal. Everybody in range can receive 100% of all communication on that network. Just by being in range the attacker can do passive sniffing. No wiretap needed like with cabled networks.
WiFi is encryoed if it uses a password. So any public WiFi without a password can be sniffed by literally every device in range (no need to connect to the WiFi for sniffing). On public WiFi with a password, the radio signal is encrypted but everybody knows the encryption key. So everybody connected to the WiFi can still sniff the traffic of everybody else.
That encryption is only on the WiFi level, so encrypted radio signals, not on the actually traffic level (like TLS/HTTPS etc).
That is the “low tech”; works 100% of the time; will make your live easier in the future solution.
It takes longer than remounting but getting rid of a NTFS drive in a Linux only environment is a good move.
