What Happens When Someone Helps You With Your Network
Recently, while I was on vacation, one of my users had problems logging in to the network and he called an IT guy he knew from where he worked previously. Since the guy was across the street, he came over and started doing some troubleshooting. During the course of his visit he connected one of our access points to our backup ISP. Later he found that the user's computer simply needed to be restarted. However, as a result of his work, the access point acquired a local address from the backup ISP and started handing out addresses in that range to clients who logged into the wireless access point. Needless to say, they were disappointed that they were unable to access the internet or the local network they were used to. A reboot of the access point cleared up the problem.
