Using ACLs to secure an IoT Network

With more and more Internet of Things (IoT) and Smart Devices showing up in my house, I figured it would be a good idea to build a separate network for these devices to live on, rather than on my regular network. Creating the actual network was the easy part, but figuring out the ACLs to block this traffic was a little more difficult. I wanted to share my experiences in case anyone else is looking to do this same thing. My Setup At the current time of writing this post, my home network is fairly simple: Ubiquiti Edge Router A […]

Will WiFi interfere with Bluetooth?

After listening to a podcast by the Clear to Send folks about Spectrum Analysis. I had some recollections about some recent conversations that I had with few people about Bluetooth devices and determining if WiFi will stop these devices from working. Let me provide you some background on this situation. Recently, I was informed about an upcoming event and the person in charge of this event wanted me to make some modifications to the WiFi we had deployed at the location. Usually, this is a custom SSID for them, but this time they wanted me to disable the WiFi at […]

Becoming better at reading by listening

Reading has never been one of my strengths. This is mainly due to the fact that it’s hard for me to stay focused while reading. I tend to daydream and by the time I have noticed, I am usually a few pages in with no idea where I started daydreaming or what was covered during this time. Knowing that this is something that I wanted to improve, but not exactly sure how I could accomplish it, I began researching some solutions. The one that made the most sense to me was listening to audiobooks, so far I have found this […]

Viewing packet diagrams in Wireshark

In one of my conversations with another wireless engineer, I was made aware of a feature in Wireshark that can be used to visually display a packet and the individual fields within it. I recall hearing about this feature a little while ago but thought it was only available in the beta versions of Wireshark. It looks like this has now been rolled into the stable release of Wireshark. After struggling for a little bit to find an exact name or how to turn it on, I figured I should write a blog post about it in case anyone else […]

Keeping track of wireless validation surveys with Google Sheets

As a follow-up to one of the previous articles that I had created. I wanted to have a backup of this data, and also be able to access it from more than just my computer. My solution to this problem is to put this data in Google Sheets since this allows me to achieve both of my goals. Also, I know that not everyone uses Excel so why not. While it is not as easy in Excel. It’s still different enough that I decided to put together another blog post documenting the steps. Starting highlight the row, column, or data […]

Tips for planning out Point to Point wireless links

In my current job role, I sometimes need to use Point to Point (PtP) Wireless links to reach some other areas that were previously unreachable. The links are mostly basic and I haven’t yet done anything too crazy relating to this subject such as detachable antennas, really long distances, or licensed frequencies, but maybe one day I will get these experiences. This is not usually my first choice but this is what I turn to when I need a reasonably inexpensive solution for connectivity. From a different conversation, Keith Parsons shared with us a great piece of information relating to […]

Building a tripod extension for APoS survey kit

Recently, I purchased a WiFiStand Wheeled Basic Kit from WIFIStand (https://wifistand.com/) after getting all the parts and putting it together everything looked great and very sturdy. After using it a few times I noticed that the WIFIStand would extend out to 8 1/2 feet to the t-bar, and the ceilings I was testing this on were 11′. I wanted to try and make these APoS surveys as accurate as possible so I set out to find a solution. I didn’t want to buy a new tripod since I wasn’t sure if the wheel kit I had purchased would fit a […]

In the beginning, these are fairly simple tidbits of advice but towards the end, I get into more detail about the tips I had for the test itself. Determine your best method on how to study This can be easy or tough depending on your environment and personality, but figure out how you learn and retain information the best. This […]

Keeping track of IP addresses with software

Over the last little bit, I feel that I am losing a bit of my networking knowledge due to doing the same thing. I decided I needed a new challenge to help me stay fresh, and that I would start separating my home network into multiple Vlans and subnets. Currently, most of the devices in my house are on DHCP, which I’m fine with, except for a handful of more critical devices that need dedicated IPs. Usually, I either rely on my memory, which is not the greatest, or my browser history to find a device. My goal is to […]
