I test this situation:

2 boards x86 1.6Ghz with 2 sr71 (5Ghz) each board.

When try 1 link with wlan1<-->wlan1 I can reach 130 Mbps TCP!! But when I start bandwidth test with wlan2<--->wlan2 same time, then two links low to 20Mbps..

Link wlan1 : 5180 Mhz
Link wlan2 : 5800 Mhz

It's clearly a huge mikrotik routeros problem Fumi22.

Why do you thing noone of official support team reply to this topic: http://forum.mikrotik.com/viewtopic.php?f=14&t=40219

They simply passed to reply cause TCP bandwidth collapsed when we use two MIMOS radio [with or without nstreme-dual]
