Bridged wireless-to-ethernet connection dropping net connect

my laptop1 picks up free wifi signal in turn from said laptop1 I have bridged connection with LAN cable to Laptop2 sharing internet connection.. works fine but drops connection every hour or so with error "Windows has detected IP conflict" should be a 5 minute fix for a network guru and pays $15 USD . you will need teamviewer to remote access my machines... payment after testing for a few hours.. thanks Paul
