ip addr

3: wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 8c:ea:12:95:a2:24 brd ff:ff:ff:ff:ff:ff
    altname wlx8cea1295a224

as you can see, it is UP

also iw dev wlp3s0 scan returns stuff

@lux4rd0 do you know what the problem could be? 🤔

[Shinigami92]

Ok, switched back to lux4rd0/wifiscan-collector/2025.7.0 and hacked again with sudo ip link set wlp3s0 name wlan0 and this is working again.
So it is not a network issue in the host.
However with the name alias, I have a ~10day memory overflow issue and need to manually restart my dhcpcd

[lux4rd0]

@Shinigami92, please pull the latest version from Docker and see if that resolves the issue. My auto-discovery didn't do as good a job as I had expected. I'll update the code tomorrow. Let me know if it fixes the issue... Thanks!

[2025.7.1] - 2025-07-18

🐛 Bug Fixes

Interface Discovery

• Fixed critical interface discovery parsing bug that caused "No wireless interfaces found" errors
• Resolved issue where interfaces with additional information lines (e.g., altname) were not properly detected
• The discovery method now correctly parses ip link show output even when interfaces have multiple configuration lines
• Added comprehensive test coverage for interface discovery with various output formats

Affected Systems

• Systems with PCIe wireless interfaces (wlp3s0, wlp4s0, etc.) that have additional interface attributes
• Environments where network interfaces include altname or other extended configuration lines
• Both auto-detection and hard-coded interface scenarios were affected
