Then, I think you wont have any better luck with ANET.

When you give no IP, it connects with "localhost", which is just the same PC. For connecting with a different PC on the LAN, you must give its IP, which on a LAN always begins with 192.168. When youre a beginner and just want to start easy, run client and server on the same PC, then you dont need to care about the IP at all.
