föck
wat does dis (>>52476773) mean?
>>
>>52476705
Radio licensing regulatory issues (FCC, et al) make that monstrously difficult to impossible, particularly with bands other than 2.4GHz.
>>
>>52476705
>No opensource USB WiFi adapters

The Linux 4.4 kernel literally just shipped with a new Realtek driver: http://www.phoronix.com/scan.php?page=news_item&px=Linux-4.4-Networking

>A new rtl8xxxu driver. This is an alternate driver for the Realtek WiFi USB devices using chipsets like the RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU. This rtl8xxxu driver was written by a Red Hat developer and utilizes the Linux mac80211 stack as a rewrite of the rtl8723au driver.

>USB WIFI
who in their right mind would want that?
>>
>>52476873
Finally.
>>
>>52477313
WiFi for a RaspberryPi?
>>
I'm pretty sure Alfa has a few open source WiFi adapters.
>>
>>52477414
I took a quick look at the driver and there isn't even any firmware in there, that I could see. So it's a fully open driver.
>>
>>52477442
Does it work well though?
>>
>>52476873
>none of those are MIMO chipsets
>only RTL8723AU supports 802.11n (just at 1x1 though)

>>52477478
Haven't a clue.

>>52477517
They're USB chipsets. What sort of throughput are you expecting over USB?
>>
>>52477587
There are cheap USB 3.0 802.11ac adapters on market, you know.
>>
>>52477636
>802.11ac
>USB

That would be retarded, though.
>>
>>52477719
You do know that USB 3.0 as 5 Gbps throughput, and 3.1 has 10 Gbps, right?
>>
>>52477757
You do know that USB has a huge interrupt & CPU overhead, right?
>>
>>52477788
3.0+ doesn't.

They overhauled how USB devices initiate data transfers, so now it works more like FireWire than USB 2.0.
>>
>>52477826
For bulk transfers. Things like WiFi adaptors tend to be isyncronous, which still has the same boring old interrupt driven, CPU taxing, overheads.
>>
>>52476705
Is that the guy who that this really weird mumbly manner of speaking in "Revolution OS"?
>>
>>52476705
Talk with the FCC when they finally let us register radios without licenses.

So, this is only useful using Aircrack-ng
>>
>>52477788
Til live usb Linux distros have huge amounts of overhead.
