I had similar issues, and purchased a network over powerline adapter kit from TP-Link. It send the signal over you homes house power line, and then a wired connection from the adapter to the squeezebox.
Very inexpensive fix, easy to et up, and no problems since.
network cable from your router to first adapter plugged into wall - second adapter plugged into wall near squeezebox, and a network cable from adapter to squeezebox. Follow simple instructions for pairing the adapters. Then turn off the wireless on squeezebox.
Amazon sells them - search for "TP-LINK TL-PA211 KIT AV200 Mini Powerline Adapter Starter Kit, up to 200Mbps"
