Task: Question Answering
Input (English): Context: However , when I go back to the laptop , I am getting no signal whatsoever . No sign the router 's even putting out a signal , let alone a strong enough of one to actually surf the Web from it . At least the Ethernet ports seemed to be working well enough , so it can serve as a backup wired router . But I decided to put the NetGear back in the network and set the wireless router on the shelf with the portable scanner I also got in that batch of computer goodies , a scanner which turned out to have only Windows drivers ( our household is Mac - only ) so I 'll probably have to sell it on eBay . 
Question: What may be the reason for selling something they ca n't use on Ebay ?
Output (English): So they can possibly get their money back .
