The Case for the Post-Install Check-In

Installing new network gear can feel like crossing the finish line of a marathon. The link comes up, the lights blink happily, and there’s a strong urge to declare victory and never look back. But that’s exactly why post-install check-ins matter. An install isn’t really done when the hardware is mounted and powered on — it’s done when you know it’s behaving itself in the real world, not just during that first five-minute victory lap.

In this case, I followed up on a Ubiquiti Wave Pro link after the install, fully expecting to see a calm, stable connection living its best life. Instead, I found the link hopping frequencies like it had too much caffeine. On paper, everything looked “up,” but under the hood the radio was changing channels far more often than it should. If I hadn’t checked back in, this would have quietly turned into intermittent performance issues and finger-pointing later on.

That’s the sneaky danger of skipping follow-ups. Many problems don’t show up immediately — they creep in once the link starts dealing with real interference, weather changes, or other radios in the area. A post-install review lets you catch these early warning signs while they’re still small and fixable, instead of waiting for a user to report that “the network feels weird sometimes,” which is never a fun troubleshooting starting point.

Following up also gives you a chance to validate your original assumptions. Maybe the spectrum looked clean during the install, but reality had other plans. Maybe auto-settings are being a little too enthusiastic. Checking back confirms whether the configuration you chose is actually the right one, or if it needs tuning. It’s like going back to tighten the bolts after a test drive — boring, but extremely effective.

In the end, checking on equipment after an install isn’t about mistrusting your work — it’s about respecting physics, RF chaos, and the fact that networks love to misbehave when you’re not looking. That quick follow-up on the Wave Pro link turned a potential future outage into a simple adjustment. And honestly, that’s way better than getting a call later that starts with, “So… this has been happening for weeks.”

Introduction: Moving Beyond Basic Benchmarking

For network engineers, relying solely on basic single-stream iPerf or simple ping output often fails to capture the true performance characteristics of a network path, especially under load. This is where FLENT (The FLExible Network Tester) comes in.

Cudy AX3000 Review - The Setup

 

Based on some limited research, I picked up a "Cudy AX3000 Multi Gigabit Dual Band WiFi 6 Mesh Router" from amazon.

https://www.cudy.com/en-us

I wont bore you with the whole 'unboxing' speech, but there's a lot to be said for a company that packages a product that doesn't

require a class in vendor unpackaging to get to the product.

It came with an installation card, ethernet cable and power supply.

Keeping in the spirit of your typical IT install, I chose to ignore the instructions and wanted to see how far I can get without having to resort to reading the manual. ;)

 

I connected the unit's internet port to my cable modem using the provided cable and plugged my laptop into the LAN port. After about a minute, I checked my and my address was on a 192.168.10.0/24 subnet with a default gateway of 192.168.10.1.

I figured I will try to access the internet and was a little disappointed that it it didn't work and I noticed the globe with the circle/line through it. 

This is important for me to know in case i consider this for some of my clients and friends who are further than a short drive away.

I figured I will just type the router IP address into my browser to see if I can access the router, or if I will be forced to download an app.  Cool, the browser loaded this page.

Its nice to see the vendor forcing you to change/create an admin password with some suggestions on creating a strong password.

I created my new password and was then prompted with a setup/captive portal.

Again, its important to me to know that until you create your password and go through the install screens, you will not have internet access.

Since my set up was DHCP based, I basically clicked by about half a dozen screens and completed the install.

As a side note, I found it interesting that the router had a few setup options that could help me out in the future.

Wireless access point in particular would be cool.  Currently, if I need a wireless access point and only have a residential router available, I disable DHCP and use the Lan port to connect to the current network.

After the install, I ran a quick Wireshark capture and noticed it was sending out IGMP packets.

I've seen IGMP enabled on a lot of residential routers and get annoyed when there isn't a way to disable IGMP. I figured "what the heck" lets see if Cudy allows me to disable it. I was pleasantly surprised when I quickly found the setting and disabled it.

The only other thing I did was change the SSID's and passwords.

Here's an interesting note: I chose to disable auto firmware updates so I could do it myself. I intentionally downloaded the incorrect firmware and was impressed that it did not blindly accept it. 

 The only thing worth noting was that after the firmware upgrade the password for my 2.4ghz SSID was a series of randomized characters, so I simply changed it back.  I only noticed because some IOT devices reported being offline after the firmware upgrade.

As far as WiFi performance goes, it did outperform my previous lab wireless router by 50 Mbps up and down as well as added some solid coverage to 2 spotty areas.

I tried to keep the first write up short and plan to do more based on different features and scenarios, so let me know if you like this format.  

For example, the next thing I want to set up is the various flavors of VPN server, VPN client and VPN tunneling, bandwidth control...

HTTPS certificate industry phasing out less secure domain validation methods

Why Your EdgeRouter Deserves Proper Name Resolution

If you’ve ever stared at your equipment logs trying to figure out which mystery IP address belongs to which device, you already know the pain. Enabling name resolution turns that mess of numbers into actual, human-readable names. Suddenly, instead of “192.168.1.37 did something suspicious,” you see “printer-that-shouldn’t-be-talking-at-3am.” It’s an instant quality-of-life upgrade that makes troubleshooting faster and a lot less rage-inducing.

I did some homework on the Ubiquiti Edgerouters that i manage and found something cool. That’s where **dnsmasq** really earns its keep. It acts as a lightweight DNS and DHCP helper that automatically ties IP addresses to hostnames. Devices grab an address, dnsmasq remembers the name, and your router logs suddenly make sense. No more keeping a separate spreadsheet titled “IPs I Hope I Remember.” It’s like giving your EdgeRouter a cheat sheet for your own network. It also helps resolve names for devices that are not configured in your DNS server like cameras and printers.

Another big win is troubleshooting speed. When name resolution is enabled, firewall logs, traffic stats, and diagnostic tools become way more readable. Instead of mentally translating IPs back to devices, you can immediately see who’s doing what. That means less time decoding numbers and more time actually fixing the problem—or pretending you fixed it and going for coffee.

Best of all, enabling name resolution with dnsmasq is one of those rare networking tasks that delivers big results for very little effort. A small config change makes your network easier to manage, easier to explain, and easier on your sanity. Your EdgeRouter already knows what’s going on; dnsmasq just helps it talk to you in plain English instead of fluent IP-address-ese.

In the video below, I use Wireshark to learn and confirm if the config change actually works.

Screenshot or It Didn’t Happen: Why Install Notes Save Your Sanity

 

There’s nothing quite like finishing a hardware install and thinking, “I’ll remember how I set this up.” Spoiler alert: you won’t. That’s where documenting installation details comes in—especially screenshots. 

In my recent Ubiquiti PowerWave radio deployment, every screen grab became a tiny insurance policy against future confusion. Instead of relying on memory (which fades faster than a 5 GHz signal in a concrete building), I captured exactly what the device looked like when everything was working.

Screenshots are especially valuable with gear like Ubiquiti radios, where settings can be buried three menus deep and labeled just differently enough to make you question your life choices. By documenting things like firmware versions, link status, frequencies, power levels, and alignment screens, you create a visual baseline. When something breaks later—and it will—you have a known-good reference instead of guessing what “normal” used to look like.

Another big win is troubleshooting and support. When you open a ticket or loop in another tech, screenshots instantly bring anyone up to speed. Instead of long explanations like “the link was green-ish but only on Tuesdays,” you can just attach proof. In the case of PowerWave radios, having screenshots from the install makes it much easier to spot what changed: a channel width, a DFS event, or a firmware update that quietly flipped a setting behind your back.

Finally, good documentation is a gift to your future self—and to anyone else who has to touch the system later. Whether that’s six months from now during a storm-induced outage or two years later when someone asks, “How was this originally configured?”, your screenshots tell the story. Taking a few extra minutes during the install can save hours of head-scratching later. In short: document early, screenshot often, and let your past self do your future self a solid.

How Windows Notepad Sabotages Your Bash Scripts (Without Even Trying)

If you’ve ever written a perfectly reasonable Bash script on Windows, copied it to a Linux box, and been greeted by a mysterious ^M or a “bad interpreter” error, congratulations—you’ve met the joys of line endings. Windows Notepad loves to use CRLF (Carriage Return + Line Feed) to end lines, while Linux expects a simple LF. To Linux, those extra carriage returns are like unexpected speed bumps, and your script trips over them before it even gets started.

The problem is that Bash is very literal. When it reads #!/bin/bash^M, it doesn’t politely ignore the weird character—it assumes you’re asking for an interpreter that doesn’t exist. From your perspective, the script looks fine. From Linux’s perspective, it’s wearing Windows shoes on a hiking trail and wondering why everything hurts.

This is where plain old Windows Notepad really shows its age. It’s great for quick notes and passive-aggressive reminders, but it has zero awareness of Unix-style formatting. So you end up writing valid Bash logic that’s wrapped in invalid line endings, and the script fails in the most confusing way possible. Nothing like spending 20 minutes debugging code that’s technically correct but formatted “wrong.”

Using Notepad++ is how you avoid this whole mess. It understands that different operating systems have different expectations and lets you save files with Unix (LF) line endings. That one small setting turns your script from “Why won’t this run?” into “Oh wow, it just works.” Moral of the story: write your Bash scripts with tools that speak Linux, or at least have the decency to translate—your future self will thank you.

How Real-Time Observability Protects Manufacturers in a Disrupted World

Keep Manufacturing Operations Secure and Resilient

from the web: Cisco IP Source Guard (IPSG) and configuration

From the website:  "IP Source Guard is a security feature on Cisco switches designed to prevent IP address spoofing attacks. It restricts IP traffic on untrusted switch ports by filtering traffic based on the DHCP snooping binding database or manually configured IP-to-MAC bindings."

In January 2026, Internetworks published several networking tutorials focused on advanced IPv6 and routing topics. The January 15 post explains IPv6 route redistribution between different routing protocols like EIGRPv6, OSPFv3, and RIPng, highlighting how to configure redistribution so routes can be exchanged between these protocols in an IPv6 environment. It emphasizes planning to avoid routing loops and using filtering, metrics, and administrative distance adjustments to control the redistributed routes, and includes an example configuration with multiple routers running EIGRPv6, OSPFv3, and RIPng working together.

Earlier in the month, January 12 featured a tutorial on IPv6 EIGRP, detailing the next-generation implementation of Cisco’s Enhanced Interior Gateway Routing Protocol for IPv6. This explained its advantages—such as rapid convergence and separate protocol instances for IPv6—and showed how to enable IPv6 EIGRP on interfaces with addressing and configuration examples. January 4 covered Cisco IP Source Guard, a security feature that prevents IP spoofing on switches by filtering traffic based on DHCP snooping or static IP-to-MAC bindings, along with step-by-step setup instructions.

My Wifi 'extension cable'

There’s something deeply unfair about having perfectly good Wi-Fi but a wired-only device staring back at you like it’s 2006. That’s where the $40 TP-Link AC750 Wireless Portable Nano Travel Router (TL-WR902AC) swoops in like a pocket-sized hero. This thing is absurdly small—about the size of a deck of cards—but somehow manages to solve problems that would otherwise involve sketchy USB adapters, driver hunting, or just giving up. It’s designed for travel, sure, but it’s also perfect for those random “why does this only have Ethernet?” moments.

The real magic for me was using it in client mode. In this configuration, the AC750 connects to an existing Wi-Fi network and then shares that connection out through its Ethernet port.

Translation: your wired-only device suddenly thinks it’s on a wired network. No OS tweaks, no weird hacks—just plug in an Ethernet cable and go. I used it to give a stubborn wired device internet access over my Wi-Fi, and it worked so smoothly it almost felt suspicious. its also a great companion for test tools that only have ethernet ports for admin or out of band access.

Setup is refreshingly painless. You power it up (USB-powered, because of course it is), connect to it, pick your Wi-Fi network, and boom—you’re done. The web interface is simple enough that you don’t need a networking certification or three cups of coffee to understand it. Once configured, it just sits there quietly doing its job, like the best kind of networking gear: the kind you forget about because nothing is broken.

The best part? This little router is cheap, portable, and endlessly useful. Toss it in a laptop bag and suddenly you’re ready for hotels, labs, job sites, or any situation where Wi-Fi and Ethernet refuse to cooperate with each other. The TP-Link AC750 is basically a Wi-Fi interpreter for wired devices, and it does it without drama. For something so small, it delivers a surprisingly big “why didn’t I buy this sooner?” moment.

Why Wireshark Display Filters Are Your Network Superpower

 

If you’ve ever opened a capture in Wireshark and immediately felt like you were staring into the Matrix, display filters are your way out. Learning to use them means you stop looking at all the packets ever and start looking at the ones that actually matter. Instead of scrolling endlessly and squinting at hex like it owes you money, you can narrow things down to exactly what you’re troubleshooting. Less noise, more signal, and way fewer “why is this taking so long?” moments.

One of the easiest and most satisfying wins is filtering by protocol name. In the video, using simple filters like dns, mdns, or nbns instantly cleans up the mess. Want to see only DNS traffic? Type dns and boom—suddenly your capture makes sense. It’s like telling Wireshark, “I don’t care about the other 10,000 packets, its just noise, packet junk or gossip.” This alone can turn a confusing capture into a clear story about what’s actually happening on the network.

Display filters also save a ton of time, which means less frustration and more confidence. When you know how to quickly isolate traffic, troubleshooting feels less like guessing and more like detective work. Is DNS slow? Filter on DNS. Is a connection failing? Filter on TCP. Instead of blaming “the network” (or the firewall, or the ISP, or Mercury in retrograde), you can actually prove what’s going on with a few well-placed filters.

Best of all, learning display filters is one of those skills that pays off immediately and forever. You don’t need to memorize everything—start simple, like protocol names, and build from there. Before long, you’ll look at massive captures and feel calm instead of afraid. And that’s a rare feeling in networking: confidence, clarity, and the smug satisfaction of saying, “Yeah, I filtered that.”

Lets play IP 'Whack a Mole'

Had such a weird problem the other day after the installation of a voice switch.

The voice switch was manually configured  with an ip address (x.x.x.2) and an old Cisco switch (model unknown) decides to grab the same ip from our dhcp server.

Here's the odd part,  I configured the DHCP scope to start at x.x.x.11.

Since I was working remotely, I disabled the upstream switch port that the cisco switch was connected to until the onsite guys could investigate.

The onsite tech told me that the cisco switch was in an area that wasn't accessible, I suggested he hang tight and I will reenable the upstream switch port connected to the Cisco switch.

I enabled the port and we waited for about 15 minutes to see if the issue comes back. I could see the devices on the cisco switch had ip addresses and data was definitely flowing. Oddly enough the switch had not requested an ip address from the DHCP server with I confirmed via the switch mac table, router mac table and DHCP server.

I told the tech "lets leave it alone for the weekend'. Monday morning I checked and the Cisco switch is still online, I can see its mac address, but no ip address.

The tech decided to 'take it out'  when he got access since it was a super old 10/100 switch, so unfortunately I could no longer do any more testing, but still a good exercise on identifying, locating and isolating a duplicate ip address scenario.

Overview of Single-Mode and Multimode Fiber Optics

Troubleshooting skills don't just happen

 

I remember a while ago when I was presenting and told the group "if you do your job right, you will always find something to fix, tune or tweak" .

After an install, I always go online the next day or two and check logs, port stats, etc..  I would say I will find something odd that is worth investigating about 30% of the time.

Over the years, I have found a lot of 100Mb POE injectors connected to 1 Gb ethernet ports and 1 Gb devices, bad cabling, 100 Mb switches/hubs on 1 Gb devices, the list goes on...

In this specific example, a new computer with a 1 Gb Ethernet interface, with new patch and structured cabling connected into a switch 1 Gb Ethernet port came up as 10 MB, and then later, 100 Mb, along with a boatload of errors.

I reached out to the client to address the issue since it can only be a few things (in order of most to least probable):

- bad patch cable at the client's desk

- bad run to the patch panel

- bad patch panel cable 

- bad switch port

- bad computer ethernet port

The clients initial response is that they are 'too busy to look at it' , and since the computer seems to be working just fine and can get on the internet, there is no urgency to address it.

Now my job is to sell, convince and educate the client that this is worth fixing before they 'notice' and it becomes a last minute support issue. :)

The Internet Protocol Journal Volume 28, No.3, December 2025

 

The latest issue of the Internet Protocol Journal mixes technical thinking with some big-picture debates about where the Internet is headed. It kicks off with the editor’s notes and then dives straight into security and governance topics, including an article on how to protect a truly borderless Internet. A major theme in this issue is Internet governance, highlighted by two opposing pieces that ask whether the traditional “multistakeholder” model is breaking down—or if reports of its death are greatly exaggerated.

Beyond those heavier discussions, the issue also slows things down a bit with a thoughtful book review of Geopolitics at the Internet’s Core, which looks at how global politics shape the Internet’s infrastructure and decision-making. There’s also a memorial piece honoring Fearghas McKay, recognizing his impact on the networking community. Shorter sections like Fragments and Thank You! add some lighter, reflective moments between the more serious articles.

Overall, this IPJ issue strikes a nice balance between deep technical insight and broader reflections on policy, security, and the people behind the protocols. It’s a solid read for anyone who wants to stay informed not just about how the Internet works, but how it’s governed—and where it might be headed next.
