I have RPI3B and I am getting terrible experiences while trying to put it online.
At my place I have access to network with cable (I need to change MAC) and to secured wifi. Both works with all other devices.
After install, I can see the wifi networks around, but the one I need was greyed out. It seems to be pretty common issue with RPI here. so I tried to follow all tutorials I found here - with no success.
At this moment I was able to change my eth0 MAC and connect at least with cable.
After installation of Wicd
I thought it can be smart idea to install Wicd. I can see the wifi I need with Wicd-curses, but it does not connect (all security settings are correct - I test it on other devices). Problem is, now I cannot connect with cable - it just do not connect, with no error (with changed MAC).
After un-installation of Wicd
Now I cannot see any wifi, nor I can connect with cable (if I change MAC). The wifi selections shows something "no wifi interface found" although accoding the
ifconfig eth0 and wlan0 are both up.
Where could be a problem? Can I somehow purge the mess after Wicd? What else instead of Wicd I can try to make the internet working on RPI?
I would like to avoid reinstalling rasspbian, because yesterday I went through the same scenario with wicd and after SD card formating I did something wrong what results bricked SD card (https://askubuntu.com/questions/894095/cannot-format-sd-card-with-ubuntu/894227#894227)
Get RPI online seems to be really expensive and exhausting fun at the end.
