I had one of those “fancy” Vodafone routers included with my broadband which had a stupid rule set on choosing the WiFi password. It’s my network, not yours, stupid router. It can be as insecure as I want.
Anyway the rules were enforced by the JavaScript so it was easy to bypass until I got my own router to replace it with.
But the blister packs we get can’t be tampered with 🤷♂️
