Hello. recently i was setting up my raspberry pi 4 to work with my networks. I have a router that is not connected to the internet which i use for my computers at home as the router that has internet access is too far, and i need cabled connections with my other computers. I connect to the internet using wifi, using the router which has internet access. At first i wasn't able to connect to the internet with the raspberry pi if i plugged the eth cable; the wifi connection was still there, and i could ssh to it over wifi, and could open vnc over wifi, but i couldn't access anything outside the local network.
After hours of searching, i found this https://www.raspberrypi.org/forums/view ... p?t=196470 and it gave me a solution that worked until i installed networ-manager following these steps https://raspberrypi.stackexchange.com/q ... n-raspbian after installing it, and purging dhcpcd5 and the other packages related to it, i face the same problem, no internet over wifi if eth cable is plugged in.
After more hours of searching for a solution, i've found nothing, so i'm wondering if anyone here happens to know how to fix that. or in case that's not possible for whatever reason, i would like to know how can i go back to the network manager that came as default with the raspberry pi without leaving anything that was done when network-manager was installed so as to not have any trouble later. As a last option, i would do another fresh install but i hope i don't have to do that.
thank you very much!
