Das gibt es also immer noch. Wie in den Nuller Jahren!

Ich habe ein Hotelzimmer bei einer großen bundesweiten und schon sehr lange existierenden deutschen Hotelkette gebucht. In der Buchungsmaske stand Classic; ich hab' mir nichts dabei gedacht.

Nach Ankunft fand ich dann heraus, dass nicht nur die Möblierung Classic ist. Viel überraschender war die Entdeckung von Technik vom Anfang des Jahrhunderts, ach was, des Jahrtausends. Das Internet war für uns alle Neuland, damals in den Nuller Jahren. Und wir waren froh, wenn ein Hotelzimmer - als unglaublichen Luxus - einen Internetzugang auf dem Zimmer bereithielt.

In jene Jahre fand ich mich zurückversetzt, als ich die Internet Access-Installation auf dem Schreibtisch sah. Aus dem Plastikkästchen, liebevoll mit einem @ als Zeichen fürs Internet beklebt, lässt sich das Kabel herausziehen. Am Ende des Kabels ein Ethernet-Stecker, den der Internet-Suchende in seinen Laptop stöpseln soll.

Doch damit nicht genug, auch die Instruktionen auf der Rückseite sind liebevolles retro:

Netscape! Wer erinnert sich noch? An die faszinierende Welt des ersten Internetbrowsers, der auch bunte Bilder ins Haus brachte?

Leider hat mein Laptop gar keinen Ethernet-Anschluss (mehr), nur noch USB-C, und einen Adapter für den Ethernet-Stecker für das Local Area Network (LAN) besitze ich noch nicht einmal. Deshalb kann ich nicht ausprobieren, ob diese Technik überhaupt noch funktioniert.

Und genauso wenig kann ich herausfinden, ob das Paradoxon gewollt ist: für das kabelgebundene Internet, so steht es in den Instruktionen, soll ich nach Verbindungsaufbau eine Zahlungsweise auswählen - eine Reminiszenz an die Zeiten, als das noch richtig Geld kostete.

Das WLAN im Hotel dagegen ist kostenlos.

10 gig switch vs 2.5 gig vs 1 gig: Which do you need?

10 gig switch vs 2.5 gig vs 1 gig: Which do you need? @vexpert #vmwarecommunities #100daysofhomelab #homelab #NetworkSwitches #GigabitSwitch #MultiGigabitSwitches #10gigswitch #SmartManagedSwitches #UnmanagedSwitches #NetworkPerformance

There are many choices when it comes to networking in your home lab or in the enterprise. The choices range from 1 Gig switches to multi-gigabit switches that offer speeds of 2.5 Gig and even 10 Gig. These switches are the backbone of any network, whether small businesses, large enterprises, or home labs, driving connections and managing data transmission. Selecting the right switch is not just…

Oh yeah! Reblogging to add my friend's tags:

#if you set your computer to a metered connection it can't update without your consent (:

This works on Windows 10, not sure about 11 yet though. (It's in the Settings menu, network settings, and I think you have to go into the settings for the specific network you're connected to. If you do a network reset, it removes that setting, so be sure to set it back afterwards!)

Also I believe no piece of software except for internet browsers should have always online internet connection. In fact, if you have something like an multiplayer game, you should go and click a very visible, very noticeable button that allows it to connect to the internet. If there is an update to an application, even your own OS, it should be in a very, very visible notification and only start with your express consent. You should be able to tell when something in your computer is connected to the internet. If you update your program in the background you should be shot.

Choosing the Right Cat6 Plenum Cable for Both Residential and Commercial Use

A reliable and high-performing network begins with the right infrastructure—starting with the Ethernet cable. Whether you’re setting up a home office or wiring an entire commercial building, selecting the right type of cable can significantly impact network stability, safety, and future scalability.

Among all the options available, Cat6 Plenum Cable stands out as a preferred choice. But not all Cat6 cables are made equal. There are variations in shielding, materials, certifications, and construction that matter—especially depending on whether you’re wiring a house, apartment, office, or large building.

This article will guide you through the key considerations when choosing a Cat6 Plenum Cable that suits both residential and commercial installations.

What Makes Cat6 Plenum Cable Unique?

Before choosing, it’s important to understand what sets Cat6 Plenum cables apart from standard cables.

Understanding the "Cat6" Specification

Category 6 (Cat6) is a step up from Cat5e in both speed and bandwidth. It supports:

10 Gbps speeds up to 50 meters

1 Gbps speeds over the full 100-meter run

250 MHz bandwidth for cleaner, faster transmission

This makes it ideal for streaming, gaming, video conferencing, file sharing, and business operations requiring consistent throughput.

The Importance of “Plenum” Rating

“Plenum” refers to the type of cable jacket designed for use in air-handling spaces like ceilings, ducts, and ventilation areas. Plenum-rated cables:

Use low-smoke, flame-retardant materials

Meet NFPA and NEC safety codes

Are required by building inspectors in commercial environments

This makes them not only safer but often mandatory in multi-floor buildings and offices.

Residential vs Commercial Needs: What’s Different?

While both residential and commercial setups need speed and stability, they differ in scale, layout, and environmental factors.

Residential Networking Needs

For a home or apartment setup, your primary goals might include:

High-speed internet for multiple devices

Smooth streaming and gaming

Support for smart home devices

Easy installation and minimal clutter

You may not always need shielding, but using plenum-rated cables ensures your home is future-proofed and safe, especially if cables run through HVAC ducts.

Commercial Networking Needs

In commercial settings, performance and safety are non-negotiable. Businesses typically require:

High-density cable installations

Long runs with minimal signal loss

Interference protection from other electronics

Adherence to building codes and fire regulations

This is where features like shielding, certification (ETL/UL), and cable build quality become crucial.

Key Factors to Consider When Choosing Cat6 Plenum Cable

1. Shielded vs Unshielded (STP vs UTP)

When to Choose Shielded (STP) Cable

Locations with high electromagnetic interference (EMI) like industrial buildings, near elevators, or around heavy electronics.

Data centers and server rooms where crosstalk could disrupt signals.

Offices using Power over Ethernet (PoE) devices, where shielding reduces heat and signal degradation.

When Unshielded (UTP) Is Enough

Basic home networks or small businesses with minimal electronic interference.

Installations not exposed to harsh environments or long cable runs.

Shielding adds cost, but it pays off in stability and signal clarity in demanding setups.

2. Solid Copper vs Copper-Clad Aluminum (CCA)

Why Solid Copper is Better

Lower signal resistance and higher conductivity

Stronger PoE support with less heat buildup

More durable over long distances

Many cheaper cables use CCA, but it’s not recommended for commercial use or anywhere performance and longevity are priorities.

3. Cable Certification (ETL, UL)

Certified cables have undergone third-party testing to confirm:

Flame retardance

Performance compliance

Build quality

ETL or UL-listed Cat6 plenum cables are not only safer but also meet legal requirements in commercial construction projects. For homes, certified cables offer peace of mind and long-term reliability.

Installation Tips Based on Environment

H3: For Residential Installations

H4: Plan Cable Pathways

Map out where the cables will run—attics, basements, crawlspaces, or ceilings. Ensure plenum cables are used in air ducts or HVAC spaces.

H4: Don’t Bend Too Tightly

Cat6 cables have a bend radius. Exceeding it can damage internal wiring and affect signal integrity. Keep turns smooth and use wall plates or faceplates to avoid pinching.

H4: Use Keystone Jacks for Neatness

Especially in homes, using wall plates and keystone jacks ensures a clean, professional finish that adds value to the property.

H3: For Commercial Installations

H4: Label Every Cable

In office networks or larger buildings, always label both ends of every cable. It simplifies future maintenance and troubleshooting.

H4: Separate Power and Network Cables

Running Cat6 cables too close to power lines can introduce interference. Maintain proper distance or use shielded cables in high-voltage areas.

H4: Use Cable Management Tools

From raceways to cable trays, proper routing tools keep cables cool, untangled, and compliant with building standards.

Future-Proofing: Why It Matters

Technology evolves rapidly. Choosing the right Cat6 plenum cable now means:

Avoiding rewiring costs later

Being ready for 10G networks, smart devices, and high-speed streaming

Supporting PoE devices as they become more common in homes and offices

Even if your current setup doesn’t need the full capacity of Cat6, investing in quality cables today ensures you’re prepared for tomorrow’s demands.

Final Thoughts

Choosing the right Cat6 Plenum Cable is more than just picking something that “works.” It’s about ensuring network reliability, safety, and scalability, whether you're working from your living room or managing a multi-floor commercial office.

To summarize:

Use plenum-rated cables in ceilings, ducts, and anywhere code requires it.

Choose shielded cables for high-interference or high-density environments.

Go for solid copper, not CCA, especially for long runs or PoE setups.

Always check for ETL or UL certification to guarantee safety and quality.

Plan for the future—even residential setups can benefit from better cables today.

A little more investment in your cabling now can save you years of hassle, maintenance costs, and performance issues down the line.

Idk I’m pretty happy in my current chassis, would maybe add some better ventilation, maybe a few more hands I could swap to, and a few more expansion slots both internal and external (oculink would be nice)

OOOOOH WIRELESS CONNECTIVITY WOULD BE A GODSEND

If you have a robot fantasy/kink, reply to this with your dream chassis. I'm so interested in what this kind of dream body looks like for folks, for totally normal reasons.
