Hello,
I am in a RV park that has WI FI, I need to connect 2 pc but only allowed 1 connection, how can I ad hoc the 2nd pc through my PC when I only have wireless connection to the internet?
you could use a router and upgrade it to DD-WRT which will allow you to use it as a bridge repeater to connect both of your computers to the router. the router in return will be the ONE device connecting to your RV WiFi.
before you buy a router make sure you can upgrade it check the website
