Hello -

I tried to set a static IP address for a raspberry pi 3b+. Tried on the client (dh....conf file - ie instructions here https://www.raspberrypi.org/documentation/configuration/tcpip/) and assigning it from the Mac address at my Orbi router. Both methods seem to give the Pi a static IP. But DNS fails always and I am unable to connect online.

I have one 3b+ and one 4b. Both have IP addresses assigned in the Orbi LAN Setup table, and both have no DNS problems.

The 3b+ is running Pi-Hole, which is a DNS server.  Before I made the permanent assignments, the Pi's both worked fine with DHCP from the Orbi pool.

 

I know this doesn't help solve the problem.  Is DNS the only thing that fails?  For example, can the Pi ping DNS servers on the internet?

Hi Yes, that was what i was trying to do to setup pihole.... i found i can't even ping to an IP address either! But, I am connected on wi-fi.. the pi shows as a client in the orbi client list..

    I set my Pi's up as "headless" and use PuTTY to SSH into them for management (or VNC for graphic interface).

    Does this Pi have a keyboard/display or it is headless?

     

    By any chance is Access Control enabled on the Orbi?

    Can other devices on the network ping the Pi?

    There are commands to disable/enable network interfaces.

    What does the ifconfig command show for the wlan0 interface?

    (IP, subnetmask, etc.)

     

    I would be tempted to flash a new SD card and start over.  With no network access, Pi-hole installation cannot have proceeded very far.
