@RMerlin is this a big in the latest 384.18 firmware or something else is happening?
Even if the wireless chip (BCM4366) supports it, I am not sure it will be available in all countries. there is no reason to provide enhanced functions for old models. This is not good for a company. Sometimes they just release a new product, like RT-AC86U and GT-AC2900 with the same hardware and the GT-AC2900 supporting 160MHz.
