Troubleshooting Internet Connections

  To produce a good trouble shooting plan, I gathered information from three tech focused websites. They all had different methods for fixing a bad internet connection. I choose the suggestions that would be most relevant and understan dable to the average user. The easiest way to solve an internet issue is to mov e closer to the router and test the network on a different device. By testing the internet connection on another device, the user can determine whether the computer is having an issue. If the other device can connect, the Wi-Fi is the problem.     After implementing these preliminary measures, the next step is to connect the computer to the router with an Ethernet cable. This direct connection can solve Wi-Fi problems. If the internet still does not work after a computer has been directly connected, it mean s that something is wrong with the router. To troubleshoot this issue, the router and modem should be rebooted . If a reboot does not restore the Wi-Fi...

Discussion 3: MU-MIMO and OFDMA

      I would explain MU-MIMO to an executive by telling them that the phrase stands for Multi-User, Multiple Input, Multiple Output. This technology allows a Wi-Fi router to send data to multiple devices at the same time instead of one at a time. A phone, laptop, and smart TV can all receive data streams at once, increasing network speed and reducing wait time. Traditional MIMO could only talk to one device at a time by taking turns. MU-MIMO is like upgrading a single-lane road to a multi-lane highway. Instead of multiple cars (devices) having to wait their turn, multiple devices can be served simultaneously, each in its own "lane."      OFDMA is like turning one delivery truck into many smaller vans, each making its own quick stop. Traditionally, Wi-Fi sends data in big chunks to one device at a time—like a large delivery truck making one long trip to a single house. With OFDMA, that same truck is split into smaller delivery vans, each dropping...
