433ah Ethernet latency

Hi Guys
I am having a problem recently got a 433AH 3 120 16dbi sectors and 3 x Mikrotik R52N-M each running a access point.
A Ubiquity Nanobridge is providing back haul is is set as a router this is feeding into a 5 port 10/100 switch which then in turn feeds the 433ah and a valemount warboard with star os running the old 2.4Ghz ap which the client wants to decommission in favour of a 5Ghz network.
The problem is when traffic is passing over the 433 the latency and loss on the Ethernet interface is severe causing any clients we have switched over to pretty much loose their internet.
I have tried replacing pretty much all the gear up there all apart from the 120 sectors and the RF cable the cables were checked for damage no signs and no signs of water in the connections. I have also tried bypassing the switch all together and using a cross over cable from the poe injector of the nano bridge to the poe injector of the mikrotik.
When plugged into the switch ping back to the internet over the Nano bridge are generally under 40ms if I ping the ethernet interface of the 433ah I get loss and extremely high Pings.

Have you set manualy the ethernet at 10Mbps?

I did and still the same result its back on auto now and is saying it has 100 full duplex

Have you enable the switch chip of the 433? - it adds some latency and loweres the output.
If you run a bandwidth test from Nano to 433, are you OK?

unsure on the switch chip I didn't knowingly enable it but I doubt that would cause 600ms + pings and 30%+ loss. From Nano to 433 link is poor have not tried a bandwidth test but again 600ms + ping and loss and that was the 2 of them joined by a crossover cable and me hooked onto one of the AP's that the 433 is running my connection was fine as far as the 433 then as soon as I try to go to the Nano problems. The nano is new as well there was a warboard acting as backhaul and same issues with that

So from the 433 to your clients you are OK and from the 433 THROUGH the LAN to the Nano, you are not?
Can you ping from the Nano's ethernet (the one which is TOGHETHER with the 433 via the switcher) to the 433's ethernet and see what you have?
You use eth1 of the 433 or another eth that goes to the switcher?

What is

add distance=1 gateway=192.168.1.10

doing??

You have it there. The wireless is fine. From the nano to the 433 is poor loss and latency. I am using port 1 on the mikrotik but we did run a 2nd Ethernet and try port 2 and just had port 1 for poe but no data connection to anything

Hmmmm......
Can you get a Laptop up there, and DIRECT ping/bandwidth test to the 433 AFTER you have unplug the Nano from the switch?
The FULL setup, EXCEPT the Nano pluged on the switch.

cheers for all the help figured out what it was one of my co-workers they put a queue but did not give it a target so it was queuing all traffic on the ap when I disabled the queue the rb performed as it should.
