First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reproducing the k2p firmware build and the listed /sys/kernel/debug/ieee80211/phy0/mt76/dbdc and iw phy checks with the latest mt76 version. Compare the reported PHY bands with the web interface showing two 5G networks and no 2.4G network; the issue names no source file or test, so completion criteria and the affected initialization path still need to be established.
