Network is OK and RUT950 is running well. But...
One equipment (Raspberry box which is running very well in itself) get an IP address (fixed address from router) from router's DHCP server but it doesn't answer to ping.
Other wifi equipments normaly get their address and respond to ping.
If I suppress the fix address in RUT950 DHCP table, the Raspberry box gets a new IP address and again doesn't answer to ping.
Strangely, the router logs don't mention this new address (I got it from my network scanner)
Could someone help me clarify ?
Thanks in advance.
let me add that this Raspberry box was running well last week with the legacy Internet box.
I have no way to ping from this "black" Raspberry box, but I can log in (via its own wifi) and it's IP address is the good one.
I have started it again and this time the router's log mentioned the new IP for this box.
But the ping from my PC still gets no answer from this box.
Here is the troubleshoot file.
