I have a boat at a marina and I have a wifi network on board, but the wifi onboard only is for local network file sharing and a printer, it isn't connected to the internet. I can connect to the marina's public internet wifi just fine and have both with two different wifi adapters on the same laptop, however, I lose internet when I do. If I just connect to the marina's wifi and disconnect the boat's wifi, I can get internet. But, that disconnects me from the printers and my network. How can I connect to both wifis and get both my own network printer and drives, and still connect to the marina wifi internet at the same time?
