Consider the following situation. I have several non-PC devices (e.g. robots & network cameras) and a PC on a wired network. The non-PC devices have an ethernet port and I plug LAN cables between them and the switch.
Normal wireless adapters come as USB sticks which you connect to the PC. So, is there a wireless adapter (battery powered) which I can plug into the ethernet port of my non-PC device which connects to a wireless router?
