I'm trying to configure OpenWRT on a Pi3. To do so properly, I need to run the Luci GUI, which for some inexplicable reason is NOT included in the official OpenWRT Pi3 firmware. As such, I have to install it in OpenWRT, as it does not appear possible to install it externally. To install Luci, I have to download it, which requires connecting the OpenWRT to my home network as a client device first. To connect to my home network, I have plugged in an ethernet cable, and it is being detected as connected to my home router, but I cannot download anything on the device.
Therefore, I am presuming that, in order to do anything with it, I first need to log in to my home network. To do so requires entering a password, as my home WiFi is password-locked. I have configured my OpenWRT Pi as best I can, following the OFFICIAL documentation: https://openwrt.org/docs/guide-user/network/openwrt_as_clientdevice
As mentioned above, despite doing so, it doesn't work.
How, and where, do I enter my WiFi password such that I can actually connect to the internet? It shouldn't be this hard.
