Problema de lentidão RB 5009

[stark]

Good morning, everyone!

I configured the network, and I'm experiencing slow speeds when many devices are connected.

The setup includes 2 business internet links, 1 RB 5009, 4 Unifi access points, 1 switch, and some wired equipment (desktops and DVR). I divided the links by VLAN, each link in a specific VLAN.

However, when around 50 to 60 devices connect, the network becomes very slow, with poor connection speeds in the DNS test (nslookup www.google.com).

Could someone help me?

Worth looking at CPU usage /system resources
And Wan interface traffic when things are slow.

A Guess:

Check the internet interface traffic when things are slow. If you have a maxed-out uplink it will usually cause things to behave poorly.

If this is the case you likely need to add some QOS to the link. Perhaps a Cake (or fq_codel) queue tree with parent being the Wan interface. (Likely with packet mark=no-mark, or no-mark and any other packet marks you use) and a max limit perhaps a bit below the supplied amount (best max-limit might take a bit of trial and error to find)
