This was taken from another thread in the General Hardware, but I don't think it will get answered because the other thread didn't address my concern, so here goes.
Here's the scenario:
I'm not familiar with networking which is why I have a question regarding that picture. Does Computer 2 have to have a ethernet cable attached to it or can that recieve Internet signals (wireless) like the PC on the bottom?
You would think as long as the cable modem or DSL (whatever kind of connection you have) is connected to a wireless router, it will broadcast that signal to all the PCs that have a wireless adapter. Can someone explain to me this?
