Wifi problems

[andyjohnson]

The case is metal -- one of these https://www.hifiberry.com/blog/new-hifib...-pi4-amp2/. But if I click the scan button in the wifi settings then it lists the SSIDs of various local wifi networks, including my "Polygon" hub and one that (from the name) I'm fairly sure is a couple of hundred metres away. So I'm pretty confident that wifi reception isn't being affected.

I ran the commands that you suggested:

Code:

andy@moode:~ $ ifconfig

(I've *** redacted the other SSIDs in the above output).

From the above it looks like the wlan hasn't sent or received and data, and isn't associated with the wifi hub. And thts about all I can get from it.

I've triple-checked the wifi password.

I'm genuinely not sure what else to try. Grateful for suggestions or observations.
