I have bought a lot of networking gear that promised to fix one thing or another.I've overpaid for said gear, too.Over time, I realized that some of the most useful upgrades weren't a $600 router, they were actually really cheap.
One of my recent small purchases actually turned out to be a lot cheaper than I thought.I'm talking about a tiny RJ45 inline coupler.It cost less than the Ethernet cable I was about to buy, and it solved a problem I had been ignoring for ages.
I had plenty of Ethernet cables, just not the right one They were good, but not great Like many people who have spent too much time messing with home networking gear, I have a drawer full of Ethernet cables and other useful stuff.As far as cables go, some are great, and some are not.Some are too short, some are too long and unwieldy, and a few are clearly super old.
Even so, with a bunch of different cables, you'd think that I'd be covered for every device in the house ...but not quite.Every time I wanted to wire something in, I somehow ended up with a cable that was almost useful, but not quite useful enough.
That's how devices end up on Wi-Fi when they really shouldn't be.If something is just a bit too close to warrant a really long cable, or just a bit too hard to make wired connectivity possible, Wi-Fi is the fallback solution.But it's not ideal, even if it's easier, which is why I had more devices connected via wireless than I'd like, including my bedroom TV.
I could have bought another longer cable, but that felt ridiculous when I had a drawer full of them.This is where an RJ45 inline coupler comes in.It's a tiny female-to-female adapter with an Ethernet port on both ends.
You plug an Ethernet cable into one side and another Ethernet cable into the other.It's a cheap fix that doesn't do much.It doesn't boost signal, add ports, or add speeds, but it makes wired connectivity possible when it wasn't otherwise.
RJ45 Ethernet coupler This 3-pack of Ethernet couplers is a very cheap networking upgrade that should always have a place in your drawer (and your home network).It lets you extend cables with minimal hassle.$5 at Amazon Expand Collapse One tiny coupler made my spare cables useful again Reusing beats rebuying The best thing about an RJ45 coupler is that it makes the cables you already own more flexible.
Two short cables that were annoying on their own can suddenly become one useful run, which is exactly what I needed for the devices that were always just slightly out of reach.That sounds like such a small fix, but it changed how I used the junk I already had lying around.Instead of treating every cable as either the perfect length or useless, I could mix and match what I had and finally wire up devices without buying yet another cable that would eventually just end up sitting in a drawer.
And trust me, there's no more space in that drawer, so getting creative was long overdue.The other nice thing is that a coupler gives you some room to experiment before committing to a cleaner setup.I could test whether a device was worth wiring in at all, see whether the connection made a real difference, and then decide later whether I wanted to buy a proper cable in the exact length I needed.

Still, a few dollars or not, it's important not to buy the wrong thing.At the very least, match it to the type of cables you're using, whether that's Cat5e, Cat6, or Cat6A.Don't assume that a random adapter with "Cat8" slapped in the title is automatically a better choice for a normal home network.
For most people, a basic Cat6 or Cat6A coupler from a recognizable brand is going to make more sense than chasing the biggest number on the listing.Deals Score networking deals: save on cables, adapters Find discounts on networking essentials — Ethernet cables, RJ45 couplers, switches, and adapters.Browse Storage & Networking deals to score real savings on accessories and gear that make wired home setups easier and more affordable.

The total cable run still matters, and so does the quality of every connection in the middle, so this is not an excuse to keep joining cables from here until eternity.If the link starts dropping or negotiates at a lower speed than expected, the coupler should be one of the first things to check and remove for testing purposes.It earned a permanent place in my networking drawer The coupler is now one of those tiny parts I barely think about until I suddenly need it, which is usually the best kind of networking accessory.
It didn't make anything massively better, but it helped me achieve my goal of minimizing Wi-Fi usage across the house, which is all I really wanted this time around.UGREEN Cat 8 Ethernet Cable Brand UGREEN Don't forget to stock up on Ethernet cables while you're here, too.These Ugreen cables are reliable and durable.
