Part of the eBay 20% off tech deal
Arguably the best AC WiFi Router available right now, with the fastest processor! This is as close to historic low as possible, grab it while you can! The last one I dd-wrt'd, I could still get the signals while being 12-storeys below it! WARNING: Might cause cancer. Buyers beware!
Price in title is before Cashback Rewards.
The optus tech recommend the airport extreme because it is easy to setup and is stable with good range.
Compromise on max speed and customiseabilty when compared to r7000.
If your household are heavy apple user (apple lappys, phones, tablets) and are looking for something that just works, airport extreme might be more stable in the long run compared to r7000.
I only say that because of a friends modem router (dlink with ac capabilities) is unstable with apple devices. I think it had something to do with the beam fowarding feature.
Airport extreme at my friends school did a good enough job to support 7 teachers and their devices. The only limiting factor was the isp's internet.
If i were you, i would choose the cheaper of the two. I am happy with my one and No real problems so far.
Only thing to be wary about nowadays is having really old devices that do not support n band. They can slow your network quite heavily when they access the router.
