Can't install Google Assistant gRPC library for Python - maybe it would be the right title of your post.
BTW what do you think about this:
Google Assistant library for Python
The Google Assistant library for Python is a turnkey solution for anyone who wants to quickly integrate the Assistant into a prototype device. The library is written in Python and is supported on devices with linux-armv7l and linux-x86_64 architectures (like the Raspberry Pi 3 B and Ubuntu desktops).
@T-NT %This thread is now marked [Resolved]. You will have wider support if you start a new thread for your problem. About your questions - hardware support of 5.4Ghz band on Omegas would be news to me - haven't seen that yet. Why the 2.4Ghz wifi isn't appearing in the polling result - confirm that the wifi SSID isn't hidden or the protocol is TKIP-encrypted, as TKIP isn't currently "automatically supported" as posted by Onion here.
Before doing anything, make sure that your base is covered. New docs here: https://docs.onion.io/omega2-docs/get-started.html
Then, you can configure/hunt for a new IP address location to suit your needs, whatever the method that you prefer. The one that works for you is the right one.
