After just under 7 years, I have worked and confirmed all 488 US Grids to complete the AMSAT GridMaster award! Many thanks to the Super and Sneaky rovers who traveled to these remote areas for activations! I have worked all of these grids portable, most from my front or back yard. All contacts were made…

MetroNet Install
Over the past few months, I’ve been observing MetroNet as they prepare our neighborhood for Fiber Internet. Now that I’ve had it for a little while, I’d like to discuss the technical process and my experience! The preparation for the project was extensive and lasted for several months. Firstly, the underground utility markers were sent…
Using Wireshark to capture Passwords sent in plaintext
This week, I will be discussing the process of incorporating a Managed Network Switch into our network, configuring a mirroring port on the switch, and utilizing Wireshark to capture a password that is being transmitted in plaintext to an HTTP website (not HTTPS). I am conducting this experiment within a lab scenario and retrieving data…
Man-in-the-middle (MITM) attack
A man-in-the-middle (MITM) attack is a cybersecurity attack where an attacker secretly intercepts and possibly alters the communication between two parties who believe they are directly communicating with each other. In this attack, the attacker positions themselves between the sender and the recipient, essentially “eavesdropping” on the communication flow. Here’s how a typical man-in-the-middle attack…
Setting up Your Ubiquiti Wireless Network with UniFi w/NSA Best Practices
This week, our focus will be on setting up a complete Ubiquiti Wireless Network using the UniFi controller software, from beginning to end. You have the option of running the UniFi OS on dedicated controllers, routers, Raspberry Pi, or Windows computers. Once the network is initially configured, the UniFi controller may not be necessary and…
Post 6: Access Point Comparison
Today, I will be comparing the features of different access points. It is advisable to purchase access points from the same manufacturer to ensure compatibility and easy setup. To manage multiple wireless access points, it is recommended to use a wireless controller for a managed wireless network. Before buying any access points, ensure you check…
Post 5: Wi-Fi Access Points
This week I will be talking about implementing a wireless network. Several weeks ago we talked about all-in-one devices that have WI-Fi built into the router. Today we will be talking about implementing a wireless network where the Access Points are separate from the router and spread through your office. After analyzing our small and…
MIMOs or Spatial Streams
The terms 2×2, 3×3, and 4×4, when related to a wireless access point (WAP) or Wi-Fi device, refer to the number of spatial streams supported by the device’s antenna configuration. It indicates the number of simultaneous data streams that can be transmitted and received between the WAP and client devices. Let’s break it down: It’s…
Post 4: Switches
This week’s topic is about adding a network switch to your network. As we mentioned before, the number of ports on your router is limited, and adding a network switch can provide additional wired ports for your network. We’ll also cover best practices and security concerns for wired networks and network switches. Let’s discuss the…
