Can I isolate a wireless router with a switch
Posted on 2010-08-13
At present my computer is wired to a DSL modem which is wired into the phone jack to connect to my Internet provider. I have always avoided wireless connections because there are inherent insecurities.
However, for various reasons, I would now like to provide a wireless connection to the internet. I assume this involves a wi-fi router. However, I would like to arrange things in such a way that none of the internet traffic from my wired desktop ever reaches the wireless router. I wondered whether a switch between the modem and my desktop, with the wireless router connected to the switch would do the trick. Something like this:
Switch ---------------------- Wi-fi router
Now I'm not clear on exactly how a (unmanaged?) switch works. On the face of it the task of a switch is to only send traffic where it needs to go, so as to not needlessly burden parts of the network (unlike a hub, which broadcasts everything everywhere, which chews up bandwidth).
So that would seem to mean that traffic between my desktop and the internet would never go by the wireless router. Is that right?
How does the switch know where to send the traffic from my desktop? Could it send traffic to the wireless router if I wanted it to? How would the switch know to do that?
