I bought the following product to get good internet in my room: AWUS036ACH 802.11ac AC1200 Wide Range USB 3.0 Wireless Adapter with External Antenna
I'm planning to buy a Pi 3 to use this wireless receiver with. Because of the distance from the router my internet connection's speed is max 40 Mb/s.
I'm wondering if a Pi 3 will be able to coupe with this speed put it in the following setup:
If Pi 3 has 10/100 Ethernet I can assume max. 100Mbps/8=12,5 MBps theoretically. My internet connection gives max 40Mbps/8=5MBps, so I can expect Pi 3 to couple with the speed in practice.(btw I know ratio 100/40=12,5/5). But from what I read a Pi 3 uses the same controller for ethernet and USB. That's why I don't know how to estimate the speed it will get. Can I expect the controller to run at full USB 2.0 and 100 ethernet speed at the same time?
Also another related issue: I have no clue whether the latest version of raspbian jessie using kernel 4.4 will support my USB receiver AWUS036ACH. It has a Realtek RTL8812AU chipset. Can someone please explain me how I can find it out without having to buy a Raspberry Pi 3 first (student budget here)?
I was planning to connect AWUS036ACH to an emulated raspbian, but I guess qemu can't redirect hardware to the virtual machine like e.g. parallels do. Anyways, yesterday I tried to emulate jessie raspbian the whole day, but had no luck finding the right kernel to use with the latest image you can download from raspbian.org (not in the mood to compile a whole OS). Someone should release a pre-packaged 4.4 kernel + img with jessie. I could only find pre-packaged images for qemu with old kernels and OS.
