My ISP provides service only via 802.11. I use laptop A most of the time. The captive portal for the service provider only allows one login per account at a time. The policy is intended to prevent multiple people sharing one account. It's just me, I'm the only user, but very occasionally I'd like to have a 2nd laptop access the internet simultaneously. No abuse, just the simple convenience of not having to logout from A if I need to use B for 30 seconds.
What I want to set up seems simple and it probably is:
WiFi Internet <---> Laptop A <---> ethernet cable <---> Laptop B
such that Laptop B can share A's active WiFi connection without having to request its own unique address from the ISP.
At present, Laptop A has its network interfaces set up so:
- WiFi is connected, active, functional. Selected the "Yes turn on sharing and connect to devices" in sidebar.
- Under the wired network properties IP Version 4, I manually set addresses to be
Laptop B has only a wired network, set to
A & B can connect directly to each other, share folders, etc.
What do I need to do in order to get laptop B to transparently use A's WiFi connection? My guess is that A needs to be set up to do some routing between the internet side and the 192.168.10 subnet, and B needs to be set up to look to A as its "ISP" ... but I don't know where to begin.
