SXT AC best settings

rextended:

Paste this on the devices. This create a transparent Layer 2 bridge with management IP.

For be totally secure you do not alter any config [I’m expecting no other item are changed from default],
install with netinstall 6.17 the routeros-mipsbe.6.17.npk without keeping previous configuration & paste the scripts.
(and remember to update the bios [firmware]!)

Some settings (band “ac”, mode “ap-bridge”, country and frequency) must be tuned because I not have at the moment one “ac”.

REMEMBER: DO NOT USE MORE TX POWER THAN NEEDED for 250m link…

PTP Start (or PTMP Start if Licence>=4 and mode=ap-bridge)

wpa2 turns your link slower, use acl instead

/interface wireless
set [ find default-name=wlan1 ] band=5ghz-a/n

Perhaps setting wireless mode to 5GHz-onlyac or 5ghz-a/n/ac might also help (on both ends) ?

My bench testing with registration signal of -50dB is giving 450-500 Mbps UDP - but only 120Mbps TCP on 802.11 80Mhz Ceee WPA2-PSK

I’ll be testing other protocols and settings and post anything if it improves.

Note - radio’s are in bridge->station-bridge mode. I’m not using WDS as this can limit performance. See http://forum.mikrotik.com/t/what-is-wds-limitaiton-with-wireless-n/30429/1

what would be the recommended tx-power for a 150m length connection?

Can you post the test results and with what settings.
