Hi All,

I am unable to connect 7i95t on raspi4 with the below settings. Ping is not sending any data. Please suggest as what I am doing wrong!

# Ethernet
allow-hotplug eth0
iface eth0 inet dhcp
        address 10.10.10.1
        netmask 255.0.0.0
        gateway 10.10.10.1
        dns-nameservers 8.8.8.8 8.8.4.4

The issue is that interface is setup for both dhcp and a static address.

I'd do a write up about how to setup an interface but for 2 reasons, it would get lost and ignored, and this kind of thing has been discussed far too many times to recall.

I think people have lost the art of being able to search.

Thanks for your reply! If possible can you share exact settings so that noobs like us can know and get this 7i95t up and running. Any help will be highly appreciated.

We can not give you exact settings as you did not reply to our questions, so go back, read and reply.

As others have mentioned, you definitely do not want DHCP and you do
need to set a static address.

You might try this:

       auto eth0
       iface eth0 inet static
           address 10.10.10.100
           netmask 255.255.255.0

DO NOT set a gateway or nameservers
