But the port needs to support the full 120. Cabling problems are on him, but if the builtin wifi can't do 120 to anything, then that's misleading advertising. Wifi is entirely capable of 120, and it's not something you can check until it's already delivered and failing.

If the grocery store makes a big deal out of having staff to carry groceries to your car, and how they sell 120 groceries, they had better be able to carry all 120 to cars that support it.
