raspberry pi is not able to connect to internet anymore after restarting

Hello! I have experience in server administration and will be very happy to check your problem with Rpi device(have like 3 at my home:)) And get it back connected to internet. Thanks!

Moin, bitte nicht bieten. grundsätzluch sollte zum neustart der Netzwerkinterfaces folgendes reichen: sudo ifdown wlan0 sudo ifup wlan0 sudo ifdown eth0 sudo ifup eth0 bzw bei neueren Systemen: bzw sudo ifdown wlx<macadresse> sudo ifup wlx<macadresse> sudo ifdown enx<macadresse> sudo ifup enx<macadresse> (am besten ein interface nach dem anderen neu starten und testen, ob es geht) Andere möglichkeit: DHCP-konflikt. Kann es sein, das sich ein anderes Gerät die selbe IP greift? Dritte Möglichkeit: der Strom, eventuell mal anderes Netztril/Kabel testen Gruß, Christian

Hi, I am Linux user on daily basis. I have experience with RPI, also had problems with an ethernet connection in the past. I can look into this and help you. Can we have a chat?

Dear Employer, If you cant reach the rpi its not possible to send any command to the rpi so you cant connect it. The only possibility is the place the SD-Card in a PC and do some modification. If I can help with that please let me know, greetings,

After starting your pi, open up the terminal and type “nmtui”, from there see if you can activate your port. If not, do a “ifconfig”, see what name your network int has, (possibly eth0), and type “ifconfig eth0 down”, and then “ifconfig eth0 up”
