Mikrotik Experts you are in need!

hello all,

i am facing an issue, i have a Mikrotik AP and stations are connected to it as customer, but while monitoring them i found that at some times they are getting the same TX data. i have a screen shot to make this understandable. can you help me to figure out the problem please ?

If they have no unicast traffic (e.g. only broadcasts/multicasts/CDP/STP), you will see exactly this, which is normal.

for sure they don’t have unicast, since i have AP BRIDGE and many customers connected to it via SXT using STATION WDS, so are you sure its normal to see this ? since these customers are claiming sometimes that they are getting bad internet service.

Put a sniffer on your network (or even use torch with all checkboxes enabled) and see for yourself.
You will probably see ARP, STP/RSTP, CDP, SMB and similar stuff. On a big L2 segment they make up a few packets/sec, as shown in your picture.

Maybe also try disabling default forwarding
