So when I play someone using wifi and running nothing else except PC/PS3 and play that same person after requesting he hardwires it, that massive improvement in connection that I feel must not even exist. It's not real and I didn't see, feel, and notice it myself. Is that what you are implying?
Don't believe everything you hear. Wireless on Mame is absolutely unplayable, but a MASSIVE difference in connection improves when the connection is wired. That's a fact,.... you can argue with it all you want....but I have my own 2 eyes, thank you.
You can lock people out....that's what I did, it prevents anyone from leeching off you. I forget how it's done, but it's a setting in your router done through the PC.
