I know there have been posts before on similar issue, but I created this because they seem to be RPI 2B. I just procured an EmonPI solar PV bundle, which is specified to be a 3B+.
I am not able to connect to my home wifi. The emonpi boots just fine, and is able to find the correct SSID (I see this by being connected via ethernet cable). But it does not seem to be able to connect anyway, even if I have typed in and verified the correct password. Both SSID and PW consist of regular letters and numbers.
I am fairly new to RPI (and Linux) world. Can anyone point in the right direction, or even better, a step-by-step description on how to solve this problem?
