Here is some information about my situation.
- All firewalls have been turned off and everything involved has been restarted multiple times.
- Client isolation on the router is disabled by default, the router is using factory DD WRT settings.
- Both computers are setup to connect to an 802.1x (school) network that uses certificates for authentication.
When I go into the DD WRT page, I can see that it has assigned two local IP addresses to both of my devices on the LAN. I wish to ping one device from another device.
Heres what happens when I do the following things:
ping < ip of other computer >
request timeout for icmp_seq 0
To my understanding this means a route to the destination was found, but it did not respond in a certain amount of time. Good job router! but why is there no response? I am 99% sure that my firewall is off, and that I am not running any antivirus software at the moment.
arp < ip of other computer >
< correct hostname! > < ip of other computer > at (incomplete) on en5 ifscope [ethernet]
Ok so my computer resolved the hostname but could not resolve the targets mac address. Am I correct in thinking that this should have resolved the mac address? Otherwise that would mean that my computers are on two different OSI level 2 networks even though they are plugged into the same router.
Does any of this make any sense? Networking is still pretty new to me, I really don't know what else I should try at this point.
Also links to articles that might help my understanding are welcome.
