Low download on Wireless - Mikrotik Audiance

Wed Feb 08, 2023 7:10 pm

Hello,

I am having trouble with download speed on wireless interfaces in MikroTik Audiance (RBD25G-5HPacQD2HPnD) . I get ~15Mbps download while upload gets to around ~350Mbps. It affects both 2.4GHz and 5GHz interfaces. Things I tried so far:
- Scanned wireless channel with WiFi Scan on smartphone and MikroTik scan in Audiance and it is clear in both cases
- changed RouterOS to 6.86 and 6.94 and the problem persists (currently running ROS 7.7)
- disabled WDS mesh configuration - no effect
- did factory reset to CAPsMAN and got ~150Mbps download and ~350Mbps - download is better, however I cannot keep this config becouse it uses NAT and basicly changes Audiance into router (I need AP only in same subnet)
- checked eth1 connection speed to central switch and I get entire 1 Gbps so the problem is in Audiance
- changed hardware - I have several Audiances and every one behaves the same

I really hope you can help me, it is bizzare that I cannot watch FHD video while uploading huge files to NAS in a matter of seconds. I attach my config below:

I managed to resolve the issue.
If someone in the future has the unfortune to have the same situation than uncheck "Unknown Multicast Flood" option in port settings at the bridge section.
I hope it helps.

If you have so much Multicast on your network that it makes this much of a difference then I'm confused - how many devices is on your network?
