Lab 14‐1: Network Troubleshooing - sthompson2752/Network-Fundamentals GitHub Wiki

This lab involved using five separate pre-built Packet Tracer files to determine the error in them through the use of troubleshooting.

Useful Instructions: Follow-the-path and spot-the-difference techniques seem to work the best for me. Most of the time the error is a small mistake made. Once the mistake is fixed, the entire network will be back up and running. benefits of wireless networks - easier network expansion, scalability, cost effective, increased mobility, installation speed and simplicity 802.11n most common > IEEE 802.11 standard defines physical layer (how many 1s and 0s move through air) and medium access control layer (layer 2 addressing and collision avoidance) > 4 physical layer technologies (DSSS, FHSS, OFDM, and infrared Wireless management protocols are authentication (determining if someone is who they say), association (allocating resources to a device), date delivery (ensure date gets to designation), and privacy (encryption)

I figured out what was wrong with each file fairly quickly. Challenge 3 and 4 were the ones that took me the longest but after about 5 minutes of thinking I was able to locate the errors in them. After doing this lab, I know it is smart to always go in with a plan when a network is not functioning as desired. If I were to go in and just start clicking and changing things, I could make the problem a whole lot worse by accident.
