I did something SLIGHTLY different than most - I used a Type32 ferrite, but I used a fairly small one - 1/2" inner, about 3/4" long, which will NOT fit the RJ-45 plug through it, so I cut them off, put 3-4 wraps (as many as would fit), and put a new end on (I usually make my own cables, so this was no big deal).  

One interesting thing I found - MOST of the RFI was NOT coming from the router end of the cable, but from the PC end!  MUCH greater reduction in signal if I put the ferrite on the PC end.  Of course, I ended up doing BOTH ends.  My birdies went from S9 to about S1, which is my background level on a GOOD  day (on a BAD day, I have S7 background from DC to daylight here)  (my antenna is a DX-EE 20ft or so straight up over my shack)
