low bandwidth with Mikrotik SXT connected to switch

RouterOS Wireless Networking
1

I’ve bought a pair of SXT 5HnD for an IP camera in a 2.5 km distance. Routerboards are working flawless and the video quality is perfect when I connect routerboard LAN directly to my laptop. But things get upside down when I connect it to a switch. Problem is not with switch because I tested another switch and didn’t help. While I get 1 to 15 milliseconds in ping in direct mode, it gets up to 3000 milliseconds when it’s connected to switch. I can’t even connect to the camera and when I hardly ever do, the video is a pain.

I’d appreciate any possible solutions.

That sounds like a network loop.

How is your network configured?

We don’t have a server on the network. That’s just 3 floors each including its own switch and all are connected to each other by a network cable.

If that’s a loop, what’s the suggestion?

Configure RSTP at your switches.
You can avoid Loops in your network

What changes should be made in RSTP? Do I have to just enable it or there are some configurations?

Thanks for your help.

You should set the priority of your central switch (which should be the spanning tree root) to something low manually so it becomes the root. Otherwise just turning on RSTP should be sufficient.

Here’s some STP/RSTP info:

Thank you so much for your suggestions. Our switch is not a manages one, it’s a normal switch. Speaking of RSTP on Mikrotik SXT, it’s already chosen on Protocol Mode.

Any other suggestions please?

r u running any other traffic over the sxt apart from ur camera video. If u have another LAN serving data usage then may be there isnt sufficient throughput across the link.

No other traffic over SXT link. That’s all a camera.

we often have problem between routerboard product and some switches that causes poor bandwidth between routerboard and switch. Usually the problem can be fixed by manually setting the ethernet port on the routerboard to 100M Full duplex, untick the auto negotiate button, and fit a cross over cable between the routeboard and the switch.

Dear vk7zms,

Thank you so much. Where is this “100M Full duplex” option? Also “auto negotiate”?
