Hi,

I'm evaluating the following setup:
- RB912 carrying a Ubiquiti SR71e card in the miniPCIe slot
- (the RB912's on-board radio is disabled)
- 2 low-gain omni antennas for the SR71e
- a laptop a few metres away
- a desktop computer directly-connected to the RB912's ethernet port

I'm measuring throughput by scp-ing a big file from the laptop to the desktop.

I'm struggling to get throughput beyond 5.0MB/s (usually I get between ~3.5MB/s and 5.0MB/s).
I know that faster speeds are possible: when I remove the RB912 and replace with a UniFi (leaving everything else the same, I get roughly 8.5MB/s.

Signal strength is good. I have an 802.11n connection.
I've configured as follows:
- wlan and ethernet ports bridged
- wlan interface mode: ap-bridge
- 2GHz-only-N
- 20/40MHz HT Below
- wireless protocol: any
- both chains enabled (0 & 1, for rx & tx)

Are there any other config items I could change to try to get better throughput?


Thanks in advance,

Alex
