I want to check differences between a frame sent by a pc connected to an homeplug and one pc connected directly with the gateway/router. When i sniff packets i cannot see any differences in the frame, the wireshark's filter homeplug-av doesn't show me nothing, I have an homeplug av but seems it doesn't send homeplug-av frames. What Im doing wrong? Any solutions or suggestions?
Example: Computer "A" connected to router, Computer "B" connected via homeplug. How can I check that Computer B is connected via homeplug, checking the sniffed packets?
Or If I connect both pc on the same homeplug, can I study the frames and check some differences with a normal ethernet frame?
