I put the wlan adapter on monitor mode and adjusted the channel to the one my router is broadcasting through, using iwconfig. In wireshark, it captures a lot of packets, but they're all broadcasts from a the access point. It's on the right SSID and the right channel, but apart from a few occasional SMC broadcasts I can't capture any traffic on the network.

These broadcast packets are useless I guess. Is the problem port related and if so, what to do?

Summarized:
-running linux
-adapter is in monitor mode

-adapter is on right channel

-only capture broadcasts, no actual traffic

Look forward to hearing from you.
