I  have a standard usb 3.0 16ft extension cord. my wifi adapter at the end of it is not fully working. which is better to do?

1) buy a power adapter for the cable, or
2) buy an active/repeater usb 3 cable.

if #2, would I have to buy a power adapter as well?

thanks.

Power adapter is for PoE [power over Ethernet]  Is the wifi adapter a PoE adapter?

It's all usb, so I was referring to a usb power hub.

A hub is a hub.  Where it gets its power from [outlet or computer] doesn't make a difference.

It would appear that you think the issue is power to the wifi device is the reason its not working.

If the device works in the usb port the cable plugs into on the computer then its the cable that is defective.

the computer usb port puts out less than a wall outlet, yes?  the problem is the best wifi spot is not near my computer, but 15 feet away.  how do you determine if it's the wifi adapter, the cable, or the power?

"the computer usb port puts out less than a wall outlet, yes?"

 No they should be the same according to the usb standard

 

Download xirrus wifi inspector.  Plug the wifi adapter into the port on the computer the cable is plugged into.  Post a screen shot of what xirrus sees.
