To Wifi or not to Wifi?

[WeApOn]

I just moved into my newly remodeled basement and I've got my PS3 setup again. I would need to run a really long CAT 5 cable through the ceiling and down to the PS3, or I could just use the Wifi.

My problem with Wifi is that it may be slow? I have used it before, but I always try to use wire-based instead.

Has anyone who has Wifi ever lost the signal? Or do you notice it acting much more slow than wired based? I would like to keep it this way but these are my only fears.

Please kill my fears .

edit-- as I type this I am noticing that my connection is MUCH faster on my PC, since my new setup brings me only 2ft from my router as opposed to having to send a wire through the entire room. therefore using wires would make my PS3 connection slower, as that used to be using the CAT 5 cable I am using for this PC now.
