I just installed RetroPie on my Raspberry Pi 2 Model B and cannot get networking to work for the life of me, wired or wireless. I have a separate sd card running Raspbian with wired or wireless working with no issues.
When I try to go into setup network, I see my network, and enter the appropriate password, only to be told “unable to connect.” I have also tried to copy my /etc/network/interfaces files and /etc/wpa_supplicant/wpa_supplicant.conf, which also doesn’t work. The light comes on my wireless dongle, but when trying to check my ip address in retropie, or using ifconfig, I never get an Ip address.
I am running an RT5370 network card, which again, works in Raspbian with no issues. I have tried everything I can think of, and am baffled. I’m not understanding why even my wired connection isn’t working. Here is a copy of the /etc/network/interfaces and /etc/wpa_supplicant/wpa_supplicant from my raspbian card, which won’t work for me.
auto lo iface lo inet loopback
auto eth0 allow-hotplug eth0 iface eth0 inet manual
iface wlan0 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf wireless-power off
