When troubleshooting, getting the specifications or WiFi details from the vendor can be daunting. if you go down the internet search rabbit hole, you typically have no idea how, or where, the information was gathered from. my rule of thumb is if i read something on the web and there is no reference links, i take it with a grain of sand.
You should take the time to go through the vendors website or ask your reseller for the WiFi specs and file it away BEFORE you have an problem.
For example, i dug up these 2 WiFi specification web pages from the apple support site that you might find helpful.
iPad Wi-Fi specification details
MacBook Pro Wi-Fi specification details
