When I used to work for a small company they had an older linksys router and were able to do it. Truth be told, because I tried to access a naughty site.
I was using my own personal laptop on their LAN.
Obviously there was no software of theirs installed on my laptop. And as I already stated, software is not an option because it doesn't take care of phones and tablets using the wifi.
So is this software that I'd be adding to my router through some kind of firmware update????
