I Switched to Ethernet—Here’s What Happened

Wi-Fi has become quite impressive; why would anyone consider running a cable? That’s what I thought until my video calls started freezing, my gaming had constant lag spikes, and my "fast" internet felt really slow. Here’s what happened when I finally decided to make the switch.

The problem with Wi-Fi nobody talks about

Let’s be honest, Wi-Fi is convenient and it mostly works. But "mostly" is doing a lot of heavy lifting here. If you’ve ever been on a Zoom call when your connection suddenly stutters or notices your gaming ping jumping from 20ms to 200ms for no reason, you’ve already seen Wi-Fi’s dirty little secret: it’s often unreliable.

Wi-Fi signals compete for airspace. Your neighbor's router, your microwave, baby monitors, Bluetooth devices all use the same radio frequencies. Even the walls in your house absorb and reflect signals. The outcome is what engineers call "interference," but what regular people call "ugh, why is my internet slow again?"

I had a good router, a solid ISP plan, and decent speeds on paper. Still, I was losing packets, experiencing jitter during voice calls, and seeing my download speeds change unpredictably. That’s when I decided to run an Ethernet cable.

• Wi-Fi ping (average): ~15ms; noticeable lag during calls and gaming, especially when the network was under load.
• Ethernet ping (average): ~4ms; consistent across every test, with almost no variation between sessions.
• Packet loss on Ethernet: 0; not "near zero," literally none recorded across dozens of back-to-back tests.

What I actually did (no electrician required)

I want to be clear: I did not break open my walls or hire a pro. Instead, I ran a CAT6 cable along the baseboard from my router in the living room to my home office, which is about 30 feet. I used cable clips to keep it neat. It took me about two hours in total, including the time I spent watching a YouTube video to remind myself how to crimp an RJ45 connector.

The materials cost me under $40: a spool of CAT6 cable, a bag of cable clips, and an RJ45 crimping kit. If you prefer not to deal with that, you can find pre-made Ethernet cables in various lengths everywhere, and they are even cheaper. Just plug one end into your router and the other into your computer or console, and you are set.

Quick tip: CAT6 is ideal for most home users. It supports speeds up to 10 Gbps at shorter distances and costs only a little more than CAT5e. You can skip CAT7 and CAT8 unless you have a specific reason. Their connectors are non-standard, and the higher price rarely makes sense for home use.

The results — and some surprises

The first thing I noticed wasn't speed; it was consistency. My internet speed test results didn't change much (my ISP plan limits that, not my local network), but the variation decreased significantly. On Wi-Fi, speeds would jump between 180 and 320 Mbps in the same room. On Ethernet, tests stayed close together at 430 to 450 Mbps, essentially maxing out my plan.

Ping dropped from an average of about 15ms to around 4ms on domestic servers. You likely won't notice this for streaming video or browsing. However, for gaming or real-time audio, it makes a big difference between feeling fast and feeling slow.

The biggest surprise? Video calls. I didn't realize how much my Wi-Fi's jitter affected call quality until it was gone. Zoom, Teams, and Google Meet were all noticeably clearer. No more "sorry, you froze for a second."

Ethernet vs Wi-Fi: My Honest Experience

• Speed Consistency — Wi-Fi speeds change constantly based on signal strength, interference, and how many devices compete for bandwidth. Ethernet provides a stable, consistent connection every time no fluctuations, no surprises.
• Latency (Ping) — Wi-Fi on a typical 5GHz band averages around 15ms ping under normal conditions. Ethernet lowers that to about 4ms. That difference feels unnoticeable for browsing but is significant for gaming and live calls.
• Setup Effort — Wi-Fi is the clear winner here. You're connected the moment you turn on a device. Ethernet requires running a cable from your router to your device, which takes planning and some effort upfront.
• Interference Risk — Wi-Fi shares airspace with your neighbors' routers, microwaves, Bluetooth speakers, and many other wireless signals. This hidden competition can lead to drops and slowdowns you might not even notice. Ethernet avoids all this since the signal travels through copper, not air.
• Device Mobility — A cable means you're tied down. Phones, tablets, and laptops that you move around the house aren't practical for Ethernet. Wi-Fi is the only suitable option for anything mobile.
• Security — Wi-Fi, even with WPA3 encryption, sends a signal that anyone within range could try to intercept. Ethernet is physical; someone would need to plug into your cable to access your network, which is a much higher barrier.

When Ethernet genuinely matters?

I'll be fair here, for many situations, Wi-Fi works just fine. Scrolling through social media, watching Netflix, or casual browsing usually won’t show any noticeable difference. However, if any of these situations apply to you, Ethernet is worth the minor hassle of using a cable:

• Online gaming: Lag spikes and packet loss can be very harmful in competitive games. A wired connection not only lowers your average ping, it also removes the worst spikes that can get you killed right as you peek around a corner.
• Remote work and video calls: Jitter, or the variation in packet arrival times, disrupts smooth audio and video. Ethernet almost completely eliminates this issue. If your calls sound choppy or you freeze mid-sentence, jitter is likely the cause.
• Large file transfers and backups: Uploading video files, syncing a NAS, or backing up to the cloud requires steady transfer rates. Wi-Fi rarely keeps its theoretical maximum speed for long periods.
• Streaming and content creation: If you stream to Twitch or YouTube, a dropped connection mid-stream is catastrophic. Ethernet removes that variable entirely.

What about Wi-Fi 6 and Wi-Fi 6E?

A fair question. Modern Wi-Fi standards like Wi-Fi 6 (802.11ax) and Wi-Fi 6E are genuinely impressive. They are faster, more efficient in crowded environments, and better at handling multiple devices at the same time. If you have a modern router and devices that support these standards, your wireless experience will be much better than with older setups.

But here's the honest answer: even a perfect Wi-Fi 6E connection still has higher latency and more variability than Ethernet. The laws of physics haven't changed. Radio waves bounce off walls and compete with other signals. For the situations mentioned earlier, a $15 Ethernet cable still performs better than a $300 Wi-Fi 6E router when it comes to latency and consistency.

Think of it this way: Wi-Fi 6 is fantastic for everything that moves, like phones, tablets, and laptops around the house. Ethernet is the best option for anything that stays still and needs reliability.

Don't want to run a cable? Powerline adapters use your home's electrical wiring to carry an internet signal. They’re not as fast or consistent as true Ethernet, but they are a solid middle ground. They provide much better performance than Wi-Fi for tasks sensitive to latency, and there's no cable running across your floor.

The verdict

Switching to Ethernet was one of those rare tech decisions where the benefits were greater than expected and the downsides were smaller than I had feared. The setup took an afternoon. The cable cost less than a streaming service subscription. The result, fewer dropped calls, smoother gaming, and consistent speeds has been completely worth it.

If your internet "feels" slower or less reliable than the numbers suggest, your Wi-Fi connection, not your plan is probably the problem. Before you call your ISP or upgrade your router, try plugging in a cable. You might be surprised by what you've been missing.

Frequently asked questions

Is Ethernet really faster than Wi-Fi?

Not always in raw speed; your ISP plan usually sets the maximum speed. But Ethernet is consistently faster when it comes to reliability. It delivers steady speeds with no variation, no packet loss, and much lower latency than Wi-Fi. For gaming, calls, and large uploads, reliability matters more than peak speed.

Does Ethernet reduce ping?

Yes, noticeably. Ethernet usually reduces ping by 5 to 20ms compared to Wi-Fi, depending on your router and environment. More importantly, it eliminates sudden jumps to 200ms+ that ruin gaming experiences—almost entirely.

What Ethernet cable should I buy for home use?

CAT6 is the best choice for most homes. It supports speeds up to 10 Gbps, is widely available, affordable, and backward-compatible with older equipment. CAT5e works fine too for gigabit speeds. CAT7 and CAT8 are not necessary for home use; they are pricier and use non-standard connectors.

Can I use Ethernet without running cables through walls?

Absolutely. Running a cable along baseboards with cable clips is clean and easy. Alternatively, powerline adapters use your home's existing electrical wiring to carry a network signal between rooms, with no new cables needed at all. MoCA adapters use coaxial TV cabling in a similar way.

Is Wi-Fi 6 as good as Ethernet?

Wi-Fi 6 is a major improvement, but it still can't match Ethernet for latency and consistency. Wireless signals are always affected by interference, congestion, and physical obstacles. For mobile devices, Wi-Fi 6 is excellent. For stationary devices where reliability matters, like gaming PCs, desktops, and smart TVs, Ethernet still wins.
