Dual chain enabled and no bandwith NV2

I am going crazy.
Point to Point Mikrotik bridge with Rocket Dish 30dbi and NetMetal5 dual chain.
Enabling only one chain (chain0) in both radios I get 130Mbps
If I enable both chains, I get only 30Mbps!

Tried all protocols Nstreme,NV2,802.11 → no result
Tried different frequencies → no result
Tried new NetMetal → no result
Tried new rp-sma cables → no result

Only 39inch far from Access Point, another identical radio and dish for another city serves 150Mbps. Swapping frequencies between them gives no result

Any idea?

6

The same

7

Why you are on 6.35.4?

8

I should upgrade?

As i said another identical link works logically with both chain

CCQ indicates interference. Why are you using 80Mhz for 130mbps? Test with 20Mhz and 40Mhz. It might work better.

The problem is DOUBLE CHAIN NO BANDWITH

12

from one documentacion on Duxtel (aus) they sad thet some times with one chanel you will get more resolt. why it is like that ask them :slight_smile:

13

Yes Upgrade,

Start testing both chains with 20 MHz and then go up,
Since Spectral Scan is missing in Mikrotik 802.11ac Equipment There is no other way.
