I am a newbie in the raspberry pi world, and I get a problem while trying to use it as a cups server. Raspbian is installed, and I put ssh up, I installed cups, and yesterday, I managed to print from my laptop, with the raspberry connected to the printer via USB, and to the laptop via the box's wifi.
Today, it didn't work. The 2 computers (laptop, with windows 10, and the raspberry pi) can't ping each other, but both can ping the box. The two IP are static: 192.168.1.78 for the laptop, and 192.168.1.102 for the other.
here is the result of arp -v -a from the laptop:
Interface : 192.168.1.78 --- 0x12 Adresse Internet Adresse physique Type 192.168.1.64 00-00-00-00-00-00 non valide 192.168.1.65 9e-97-26-89-30-16 dynamique 192.168.1.99 00-00-00-00-00-00 non valide 192.168.1.102 00-00-00-00-00-00 non valide 192.168.1.254 9c-97-26-89-30-16 dynamique 192.168.1.255 ff-ff-ff-ff-ff-ff statique 18.104.22.168 01-00-5e-00-00-16 statique 22.214.171.124 01-00-5e-00-00-fb statique 126.96.36.199 01-00-5e-00-00-fc statique 188.8.131.52 01-00-5e-7f-ff-fa statique 255.255.255.255 ff-ff-ff-ff-ff-ff statique
I don't know why the physical address is 00-00-00-00-00-00 for xx.xx.xx.102.
here is the content of the file /etc/dhcpcd.conf: I added at the end:
interface wlan0 static ip_address=192.168.1.102/24 static routers=192.168.1.254 static domain_name_servers=192.168.1.254
googling didn't help me so far.
