Be honest: When did you last check your Ethernet cables? If the answer is "probably not since I've installed them," I can't blame you.I also didn't care about the state of my wired connections until they finally backfired and prompted me to investigate.An Ethernet cable is the type of thing you connect once and just leave it be for the rest of time.
I still have Ethernet cables in my house that I've been using for 12+ years, and they still do their job.But many people aren't aware of the fact that there's more to Ethernet than it seems like at a glance, and sometimes, a simple cable can cause some serious issues.I thought Ethernet was the reliable part of my network I side-eyed Wi-Fi, but never my wired connections Ethernet totally deserves its reputation as the more stable option compared to Wi-Fi.
In fact, I avoid Wi-Fi like the plague on most devices in my home.But that doesn't mean that every Ethernet connection is automatically healthy and just generally "the best." Wired connections can still hide flaws that don't really show up at a quick glance.A wired connection cuts a lot of the wireless nonsense, that's true.
Interference, range problems, crowded channels, Wi-Fi dead zones ...No problem.However, it can't fix the fact that you still need a good physical connection between the device, the router, the switch, or the mesh node.
That's where the cable itself becomes more important than most people give it credit for (it's me, I am "most people").I have some Ethernet cables that are older than today's middle schoolers, but just because they work doesn't mean they're perfect for the job.You might find your device connects at 100Mbps instead of 1Gbps; you might deal with packet drops or tiny disconnects; you might see inconsistent network performance.
All of those can lead back to your Ethernet cable, and it doesn't have to be a big issue for it to still be a nuisance.Even small stuff like a broken clip, a loose connector, or a sharp bend near the plug can be enough to cause a mess.UGREEN Cat 8 Ethernet Cable $8 $10 Save $2 Brand UGREEN I'm not a fan of spending money without need, but if your Ethernet cables are truly ancient, this cheap Cat8 cable can be a surprising network upgrade.
$8 at Amazon Expand Collapse The label on the cable matters, but it's not the end-all, be-all Cat5e doesn't mean it's trash The easiest place to start this whole Ethernet clean-up mission is to look at the tiny print on the cable jacket.Somewhere along its length, you'll usually see whether it's Cat5e, Cat6, Cat6A, Cat7, Cat8, or something else entirely.This gives you a rough idea of what the cable was designed to handle, and it's worth checking if you're still using whatever cable you dug out of your drawer 10 years ago.
That said, the label isn't a guarantee that the cable is either good or bad.Cat5e is old, for instance, but it's not like it's useless.For a regular gigabit Ethernet connection, it can still be perfectly fine, assuming the cable is in decent shape.
If your router, switch, or PC can only handle 1Gbps anyway, then there's no point in swapping the cable if it works.Cat6 is where I'd draw the line for most new cables today.It's cheap, easy to find, and gives you more room if you're dealing with a 2.5GbE port.
Cat6A makes more sense if you're wiring through walls or planning for longer 10GbE runs, but for basic patch cables between a router and a nearby device, it's often more than most people need.The key is to match the cable to whatever it is your device is meant to be doing.Related I upgraded to fiber and my Wi-Fi still lagged: How to find the hidden bottlenecks in your home network Your fiber internet is fast, but your home network probably isn't Posts By Monica J.
White The cable can look fine and still be the problem Some signs are obvious, others are very much not All the labels aside, some Ethernet cable issues are easy to spot.If the plastic clip is broken, the connector won't lock into the port properly, and that alone is enough for the cable to become e-waste.The same goes for a cable that's badly frayed, crushed, sharply bent near the plug, or loose enough that it disconnects on its own.
And yes, cables that have been chewed on are also disqualified, shout out to my beloved pup.Some problems are less obvious.Ethernet cables rely on twisted pairs of wires inside the jacket, and if those wires are damaged, poorly terminated, or bent, the cable might not fail outright but still be downright useless.
Link speed negotiation can quickly expose a bad cable This can help decide which cables need to go One of the quickest ways to catch a bad cable is to check what speed your device actually negotiated with the router, switch, or Ethernet adapter.If a PC with a gigabit port is only connecting at 100Mbps, that doesn't always mean the cable is necessarily busted, but it does make it pretty suspicious.At that point, don't throw the cable out just yet.
Check the link speed in your OS, your network settings on your router, or your switch interface, if you have one.When in doubt, replace with another cable and see how it goes.Cable drawers need some standards too All these network-related fumbles and misfortunes made me treat my cable drawer with a bit more suspicion.
A random old Ethernet cable is fine for testing, and may even be fine in general if you test it and it all comes back in perfect conditions.Those things are real champs, and they can work fine for years and years.But if you're trying to achieve optimal network performance, and I mean that in terms of speed, stability, and latency, keep a couple of known-good Ethernet cables around.
Cat6 or Cat8; either will do.It's more about having cables you can always trust than buying the most expensive option available.TP-Link USB to Ethernet Adapter $12 $13 Save $1 This little guy is another must-have I keep a few of at home.
It can help you connect via Ethernet even on devices that don't actually have the port.$12 at Amazon Expand Collapse
