The BR-6478AC is powered by a Realtek RTL8197D processor, which makes the Edimax the second Realtek-powered AC1200 router that we’ve looked at. I combined the tables from other reviews with the summary of the Edimax' key components below so that you have a side-by-side comparison of all the AC1200 routers that we’ve reviewed.
If you look carefully, you’ll see that the Edimax router shares the same Realtek components as the D-Link DIR-850L. Like the TRENDnet TEW-811DRU, the Edimax has only 64MB of RAM. All of the other routers have 128 MB. At 4 MB, the Edimax also has the least amount of flash of any of the routers in the chart.

The image below shows the component side of the BR-6478AC circuit board. In the upper right corner, you‘ll note what appears to be the 5 GHz Mini-PCI module with black coaxial cables leading to the two dipole antennas. In the middle of the board, you‘ll see two gray coaxial cables coming from the Realtek 8192CE 2.4 GHz radio module that connect to the dual-band antennas. Those are heat spreaders covering the switch and main CPU.

The unloaded component pads provide some interesting insight into possible future Edimax AC routers. The two connectors to the right of the LEDs look like they would support USB. And the components to the right of the 2.4 GHz radio look like they could hold a possible future on-board 5 GHz radio.
As noted in the introduction, the Edimax BR-6478AC has a fairly basic feature set, so I won’t describe the details of each menu. Instead, I’ll comment on features, or lack thereof that differentiate it from other routers. The image below, taken from the Edimax website, summarizes the features and specifications of the BR-6478AC.
Edimax BR-6478AC Features and Specifications
To administer the router, you either point your browser at http://edimax.setup, or to the router’s default IP address, which is 192.168.2.1. The password prompt dialogue shows that the default credentials are admin/1234. This is a nice feature in case you’ve misplaced the Quick Install Guide. But it's a wide open invitation for trouble if you haven't changed the default password, which the setup wizard doesn't make you change.
Here's the landing page. You’ll note that it has a fairly typical layout with top-level menus arranged in vertical tabs along the left side of the screen. The home page presents a top level status, though it doesn’t show router uptime.
