The key to unlocking this Wi-Fi puzzle lies in something called DNS, or Domain Name System. Think of it as the phonebook of the internet, translating website names into the numerical addresses computers understand.

For some reason, my Mac tends to cling to old DNS information, even when it’s no longer relevant. This can cause conflicts when trying to connect to new networks, especially those with less-than-stellar security.

So, what’s the solution? You need to give your Mac’s DNS a little “forget-me-now” treatment.
