Hello MikroTik,
I've been experiencing some troubles with 7km link and 2x2 R52N on RB411AH.
Link quality is 100/100 CCQ 270/270Mbps but after 40Mbps link disconnects and I see constant 100% cpu usage on 25/30Mbps.
I've removed connection tracking, unneeded services ftp/ssh/www, there is no firewall.
I've tried two setups:
1. MPLS transparent bridge
2. WDS bridge
Both show same result and I'm not happy with it.
I have two other links with RB600A & X86 Intel boxes and there is no problem with these links.
I wanted something cheaper with rb411AH and I got worse result than with 802.11a 40Mhz setup( which was ~60Mbps ).
Do you have any idea why is that happening?
