Hello There! I have done a PtP wireless links with router board RB433 with two wlan cards R52HN (dual chain). I have done ap-bridge wireless configuration mode on RB433 board and station bridge on the another sites. All the other station sites are at different directions. So i decided to utilize the dual chain R52HN radio cards with single chain 24dBi grid antennas for different location based station directions that is four different directions with chain0 connectors to two directions and chain1 connectors to another two station directions. For chain0 link connectivity at station end i have used Mikrotik groove52Hpn having single chain0 and link connected good with Rx/Tx signal strength -65/-63dBm. For chain1 connectivity i am using Mikrotik dual chain DISC Lite 5 with activating both chain0 and chain1 on this station end, as there is no radio with single chain1. But chain1 is not making link from AP base site to this dual chain DISC Lite 5 station. It must work at least with chain1 on this dual chain DISC Lite 5 station. Why this is so it must detect the station and get connected? Any link connectivity technical support will be appreciated from Mikrotik Wireless Network Exert here. Thank you very much.
LOL Tell me this is a wind up please.
This is Not going to work
Dual Chain doesnt work like two siso Radios
Sorry! Didn’t understand Bro. Please clear 
Thank you very much for your kind reply to my post.
Ok. I will give it a try. If I am wrong someone has to correct me as I do not have that much
know how about networking.
Try to separate network radio chip, from the word “chain”. There are single, dual or triple -chain
for WLAN. The “chain” it self represent a path to the radio chip. A single chain will
give you something like 30-50Mbit throughput if you are close to the AP.
If you have additional chains it will increase your total speed. Think of triple chain as virtual
paths of data sent to and from your laptop or device connected to the AP. So each radio chip
will work on a the frequency you set, and the chains are then virtual path within that frequency
and operate like it is one big path of data that you transmit or receive. I assume that the
more clients connect to the AP the more the speed is reduced they share the amount of
data within that path and one drawback of 2.4Ghz network is that only one client at a time
can send or receive data at a time. So if there are to many clients connected it will
become real slow if all of them want to use the WLAN at the same time.
Hmm, wonder if I got that right of it I am just confusing my self ?
