    Hi folks,

    I saw a few other posts that also describe this issue.
    Issue: After updating or install 7″ plugin, wifi will not connect to a wireless network.

    Here are the steps to reproduce the bug:
    * Download either the HiFiBerry image or the 7″ Display image
    * Install works (2.32) – Updating to the latest (2.33 or 2.34) or beta Max2Play causes WiFi to stop working (NO CARRIER)
    * Install (from HiFiBerry image) using either image, using WPS works on reboot. – Install the 7″ display plugin after reboot causes WiFi functionality to stop working

    The problem appears to be some dependancies that occur from apt-get update, probably tied to the 7″ driver or config files. Running the appropriate wpa_supplicant commands, editing /etc/network/interfaces do not help.

    I would be happy to get logs and send them, this is rather frustrating

    Hello Derek,

    Did you expand your filesystem?

    Could you give me the debug info of the WLAN?

    Best Regards

    The first few times I tired, I did expand the filesystem. The current install, the file system is the default size.

    I’m connected via eth0 right now, so it won’t say NO CARRIER.

    Are there some commands you would like me to run?

    Hello Derek,

    Sorry for the late reply. Your problem could be the power supply. If you use same time a Raspberry Pi, 7″ Touch Display and a HiFiBerry, you need an additional power source for the display.

    You should see a symbol at the right upper corner, if not, please first test it without a hifiberry sound card.

    I have tested your setup and it works fine.
