NStreme Dual droping out

RouterOS Wireless Networking
1

I have a Nstreme Dual PtP link that drops out about 36 hours after it starts. I disable and enable the connection and it shows connected but no traffic until I reboot the second end.

Here is my setup. Both sideds of the link is RB333 with XR5 cards in the No:1 board and RB333 with SR5 and CM9 in the No:2 board. Both are running 3.11 OS with firmware 2.15. I am using a Radiowave 32dbi dual pole dish on each end. The link distance is 20 miles. The signal is -56 to -59 with the XR5 Freq 5745 on the Vertical Pole. The CM9 is for receive only and shows about -60 to -62 with a freq 5180 on the Horiz pole. CSMA is not disabled and the system is running OSPF.

I have disabled Nstreme Dual and have gone back to simplex and all seems to work so I dont think it is a card issue. I also dont think it is an interference problem because Im the only one on the tower and my dish is pointed to a remote area.
Any thoughts?

What about the configuration for other Nstreme parameters ?

I have left all other settings as their default.
The Nstreme interface settings showing is Framer Policy-none Framer Limit-2560
Now on the Tx card side I just checked enable Nstreme its Framer Policy shows None but the Framer Limit shows 3200. These I have not changed or tried as I assumed it was defaults.
What I did notice was when things were working, the Nstreme interface showed a lot of TX-Retries time out and TX-Retries Lost. I didnt know what to think of this. I was also trying to do a fail over encase the Dual-Nstreme failed at the 2 unit to another simplex unit I have in town. That way it the Dual failed to make it to my distrubution point the second feed from town would take it’s place. But as luck would have it, it didnt transfer over so I need to find a solution to dual gateways, one gateway DualNstreme and the other Simplex.
