Try this (or similar) solution: http://www.dummies.com/computers/pcs/how-to-share-your-laptops-internet-access-with-another-pc/

In your case it's better to share a wired connection of your PC. Also a DHCP server on your PC is necessary too, I guess. Here is the first link I found: http://www.dhcpserver.de/cms/

But the simpliest solution for you will be a new suitable, robust, simple router like Zyxel Keenetic Viva.
