but you have to understand that it's not just Asus they can only fix what is available to them, some of it is closed off by Broadcom and trend micro.
It is just Asus as only they have contact to Broadcom to get working drivers for their chips. And they got the power to force them otherwise no business!
If they cant get it they would have to use other chips on their routers, but its completely wrong to say its not only Asus problem.
If you build something (house, car, router, whatever) and sell it to customers using faulty components (drivers are part of the chip!!!) or for your purchasing free "features" its ONLY YOU who is responsible for that, nobody else in world!
You use it because these components are cheaper or offers more advanced features and you want to sell for a better price than others to increase your business.
And you sell it fully working with these features, so its up to you to take care you can deliver what you promised!
If you are willing to pay twice the price in Down Under with full support (if you really get it) is ok.
But I would take the risc and buy instead two units for the half price each.
Never got helpful support for my Asus products here in EU!
And I had 10 different Asus products in the past all bought whithin EU!
So I decided to change my mind and get my last 86U from china half a year before they have been offered here.
