Wired typically offers a substantial performance increase, so if speed is important to you, go wired.

As of TiVo software 7.x, USB 2.0 is enabled. Of course, you have to have a USB 2.0 adapter.

How old is your TiVo (what are the first three digits of your TiVo service number)? If they are 140, your hardware only supports USB 1.1, if they are 240 or higher, your hardware supports USB 2.0.

EDIT - I agree -- wired is faster and not susceptable to interference from 2.4 GHz devices like cordless phones and baby monitors from your home (or from your neighbors!).
