No Internet on Raspberry Pi and display problems

Sun Jul 12, 2020 4:13 pm

I have a Raspberry Pi 4 that I bought recently and I have managed to flash Raspbian onto an SD card and boot it up. I have a few things installed, but recently, I have noticed that my internet has not been working at all, and I frequently lose display connection. I have set up a static IP address using

Code: Select all

dhcpcd.conf
and rebooted to see if they connect, and only the Ethernet is connecting. However, I still can't access the internet, and all the testing I have done reveals that running the command

Code: Select all

service dhcpd status
results in the output

Code: Select all

pi@raspberrypi:/media/pi/Seagate Barracuda 1TB/Scripts $ service dhcpcd status 
● dhcpcd.service - dhcpcd on all interfaces
   Loaded: loaded (/lib/systemd/system/dhcpcd.service; enabled; vendor preset: enable
   Active: active (running) since Mon 2020-07-13 22:02:54 BST; 1 day 13h ago

Jul 14 22:41:54 raspberrypi dhcpcd[422]: vethbb12183: deleting default route
So the service is running, but I cannot connect to the internet on my Pi. How can I fix this so that I can use the internet on my Raspberry Pi? In addition to this, I am also noticing that my Pi's connection to my HDMI monitor is frequently dropped, and booting my Pi results in a "No signal" message on my monitor. I don't know what to do.

I have also tried to ping Google's IP address, using the command

Code: Select all

ping 8.8.8.8 -c 4
and I get the following result, yet I still cannot connect to the internet.

Code: Select all

pi@raspberrypi:/sys/class/leds/led1 $ ping 8.8.8.8 -c 4
