The maker advertises that as many as 5 of these 16 ft cables cables can be connected together to reach 80 ft.. I could only hook 2 of them together for a total of 32 feet for a Linksys WUSB 11 wireless wifi receiver. I could get as many as three hooked together on my memory stick for test purposes.

There was a small note of "caution" on the bottom of the package stating that you should check to see how many you could hook together. Of course I didn't know this until I bought them.

Ahh the fine print
