Packet Loss when RB750 connected Multiple SXT in bridge mode

Hi All,

Here I am facing issue with connecting RB750r2 in all ports are in bridge and connected with multiple Wireless devices such as DynaDish and SXT. I have added the topology.

I have hard code speed and duplex 100 Mb full in all interface which are connected.

When ever I connect on this RB750 after a few minutes continuous drops happening and after two to five minutes, i will come back again and its happening intermittently. If I connect this all to a switch everything will be fine, no packet loss and no significant latency.

Could any help how to find the cause of this issue ? Since the ports are in bridge and it is working with a small 5 port switch without any issue, what all could be the reason for this behavior.
