CAT5 and other structured cables are great for this purpose BECAUSE they 
consist of four high quality twisted pairs. To minimize crosstalk 
between those pairs, each pair is twisted at a different rate (turns per 
inch).  When using these cables to carry signals, it is absolutely 
critical that we use one of these pairs to carry our signal (and 
multiple pairs to carry multiple signals).

In any given system, WiFi transmits on only one of many standard carrier 
frequencies, and it doesn't run much power. I don't work 2.4 GHz, but 
I'll bet that like other ham bands, our use for CW, SSB, and other DXing 
modes is limited to a narrow range of the band, just as it is on 440 
MHz.  I wouldn't give up on that system simply because it's in the same 
band unless the WiFi gear is dirty. Have you observed that it is?  If 
so, that is, indeed, a good reason to avoid it.
