One day, I came across a ticket dealing with network drops not working so being me I took it. When I got to the school I started to investigate with the campus tech. I was confused at first at what could be happening and was just about to blame the desktops themselves but the behavior was so random. Once troubled desktops would start connecting to the network again and those that did work, would stop connecting. They would connect to another network. With the guidance of a network specialist, we were able to conclude that something else was connected to the network that should not have been. Something that was handing out IP addresses and creating its own network.The specialist informed to download Wireshark which I have used before and take a look at the packet capture. He pointed otu we needed to look for a 192.168.x.x network which I did find. I found the IP address 192.168.0.1 and I tracerouted it to see what information it would give me. The traceroute would let me know that it is a Linksys router that was attached. So I retrieved the MAC address from the packet capture and asked the network specialist to trace it to the switchport. He told me what switchport it was. The campus tech and I started to look for this device and eventually found it and took it off the network. The problem was finally solved.
Marquee issues are always challenging to take on. There was a marquee issue at a school that needed to be checked. The user informed that messages would not send to the marquee all of a sudden. My first troubleshooting steps are to ping the marquee and check connections. At first we could not figure out how the marquee was set up so I had to call Spectrum. The tech on the phone walked me through different steps and I was able to find the marquee was connected to the building via fiber cabling. I also opened the marquee and was able to ping it directly connected to it which meant something was wrong with the fiber cabling or the fiber converters. Just verify, a network specialist helped and he suggested another way of making that connection to the marquee. He suggested a wireless bridge using two TP-link access points. We went the idea, got them ordered, configured them, installed them, and tested the,. The communication was back up and the user was able to senf messages to the school marquee again.
