Q: El Cap, wifi error 3905 on previously OK connection

Hi,

My Macbook running 10.11.5 suddenly dropped the WIFI connection citing a message "Cannot join WIFI network X, please move closer" or something along those lines.

My other devices still connect. This device has always connected. As far as I'm aware no one has tampered with any settings. One moment I'm using it, the other moment it's faulty.

When trying to connect through the command line, I get the following error code:

com.apple.wifi.apple80211API.error error -3905

The only answers I can find are regarding Apple TV and *seem* not applicable.

In the meantime, I have tried:

restarting macbook
deleting all network related settings in /Library/
restarting modem
changing modem channel
resetting PRAM
resetting SMC

To no avail. Does anyone have any suggestions?
