Master/AP mode: All packets are dropped when signal decreases

[AaronMcHale]

Hi, no idea where to start with this, so I'll describe my setup:

• Raspberry Pi
• Arch Linux (4.0.8-3-ARCH)
• USB 3.0 Powered Hub
• Alfa AWUS036ACH USB 3.0 Wireless Adapter
• tried both this driver and the fork by @csssuf https://github.com/csssuf/rtl8812au
• hostapd 2.4 with the RealTek driver patch https://github.com/pritambaral/hostapd-rtl871xdrv
• the above hostapd build with the noscan patch https://dev.openwrt.org/browser/trunk/package/network/services/hostapd/patches/300-noscan.patch

Everything is fine when connecting near the antennas, however when I'm further away say through a few walls the signal is still good but there is huge packet loss, to the point where google (for example) just won't load. The strange thing is I don't get this problem when I connect the adapter to my Windows Desktop and use the RealTek software

So I thought I would post an issue here and see if anyone had any solutions.

Thanks
Aaron
