I second trying a quality router. My sb3 ran pretty flawless both wired and wireless as well as the transporter.

Get one that supports upgradable antennas.

Also you might consider using Powerline ethernet for receivers which solves wifi issues for some folks.

I run open source firmware on my linksys that is totally awesome. It supports tunneling and Wake-On-Lan. So I can vpn in, turn on squeezecenter server and stream music to work by transcoding to MP3 192kps and use web browser to select music. I think I could even do this to my pda phone.

If you think listening to music is fun, try learning an instrument.
