the enternet dont work like that guys. a longer the cable will not affect this in anyway. as far as making the lag last longer, good luck, it will only lag for a set amount of time before your connection times out due to lost packets of data. you could get very involved with it and write a program that will hold segments of data up to a timed point (just before time out)
as afr as extending the cord with extra wire...no..yo ushould buy a longer ethernet cable, every break in an ethernet cable will slow transfer rates more and more, this seems logical due to the way we just add more wire to the led's to make the wire longer, but in that case we are sending power, not data.
that only other thing I can say about this is, rapid fire is one thing, but its still cheating.. there is no doubt that this mod will only be used online..and the user is a CHEATER. if your ok with that. please proceed
