really the fastest and most secure for both laptop is a wired connection, wireless certainly is more convenient for laptops beacuse it cuts a cable outof using it and makes it mobile, at the expense of speed and security. a tower that doesn’t need to be moved would benefit for speed and reliability of a wired solution unless placement makes it impossible. most wireless routers have st least a few sockets for wired connections which I personally use fo my storage server and my printers, and stationary computers if I had any.
