Your comment motivated me to check if I could make my home router fallback to my second connection (I flashed it with OpenWRT). After fiddling with using usb wifi dongle as second wan entry and looking over if any nearby electronic shop has usb lan adapters in stock, I discovered that my router has vlans and I can "rob" one switch port for second wan. So I set up mwan3 and have more and more respect for what one can do with Openwrt and off-the-shelf router.
