We’ve had multi-gig networking for several years now, but where does it actually make sense? I think that multi-gig internet is a waste of money, as most servers can’t serve you files at those speeds anyway. However, a multi-gig LAN absolutely changed how I use my homelab.
You can only download as fast as a server can upload
You could have 100Gb/s internet, but still only download games at 1Gb/s
I’ve had gigabit internet for nearly seven years now, and I absolutely love it. AT&T started offering 2.5Gb/s and 5Gb/s network plans at my house a few years ago, and I will say, I was initially tempted. The problem with multi-gig internet, though, is that you still are limited by the server you’re downloading from.
A good friend of mine has 3Gb/s internet at his house. His networking equipment is set up to handle it, too—at least up to 2.5Gb/s. The amount of times he actually gets the full 2.5Gb/s download speed on things is very few and far between, however.
Take Steam, for example. Some Steam servers are multi-gig ready, but most still cap out around 1-1.5Gb/s if you’re lucky. Epic, EA, and other game stores are limited by the same thing. Even for myself with gigabit internet, there are many, many times when I don’t even fully saturate a gigabit connection.
So, you can have multi-gig internet all you want, but you’ll still be limited by the place you’re downloading something from. Loading web pages isn’t any better, as those servers are limited by the same issue and there’s also a point of diminishing returns, where just because you’re downloading a website’s contents faster doesn’t mean there’s much of a perceived difference.
Mesh WiFi networks: history, tech, future
Trivia challenge
From military roots to whole-home coverage — how well do you really know mesh WiFi?
HistoryTechnologyBrandsFuture TechFun Facts
The concept of mesh networking was originally developed for use in which field before it reached consumer homes?
Correct! Mesh networking grew out of military research, particularly DARPA-funded projects aimed at creating self-healing, decentralized communications that could survive partial network destruction. The idea was that if one node went down, traffic would reroute automatically — a very useful feature on a battlefield.
Not quite. Mesh networking has its roots in military and DARPA-funded research, designed to create resilient, self-healing communications networks for battlefield use. The decentralized nature meant no single point of failure — a concept that later translated beautifully to home WiFi coverage.
What is the primary technical difference between a traditional WiFi extender and a true mesh WiFi system?
Spot on! True mesh systems use a dedicated backhaul — often a separate radio band — exclusively for node-to-node communication. This keeps the bandwidth used by your devices separate from the bandwidth used to pass data between nodes, resulting in far less congestion and much better performance than a traditional extender.
Not quite. The key differentiator is that true mesh systems use a dedicated backhaul channel between nodes, keeping device traffic and inter-node traffic separate. Traditional extenders reuse the same band for both, effectively halving available bandwidth — which is why they often disappoint in practice.
Which company is widely credited with popularizing consumer mesh WiFi when it launched its first product in 2015?
Correct! Eero launched in 2015 as one of the first consumer-focused mesh WiFi systems and essentially kicked off the home mesh revolution. Its simple app-based setup and attractive hardware stood out in a market dominated by ugly router boxes covered in antennas. Amazon later acquired Eero in 2019.
Not quite — Eero gets the credit here. Founded in 2014 and launched to consumers in 2015, Eero was a pioneer in making mesh WiFi accessible and appealing to everyday users. Its clean design and smartphone-based setup felt revolutionary compared to traditional router management interfaces.
A mesh WiFi network behaves similarly to which surprisingly ancient human communication system?
Great analogy — and you got it! Mesh networking mimics the way gossip spreads: each node receives information and passes it along to the nearest neighbor, with multiple paths available if one route is blocked. Computer scientists actually call one mesh routing method ‘gossip protocol’ for exactly this reason.
Fun guess, but the best analogy is gossip spreading through a village. In mesh networking, data hops from node to node along the best available path — just like a rumor finding its way through a crowd. Computer scientists even formally named one routing approach ‘gossip protocol’ in honor of this similarity.
WiFi 6E and WiFi 7 mesh systems introduced support for which frequency band that older mesh hardware cannot use?
Correct! WiFi 6E opened up the 6 GHz band for consumer use, giving mesh systems a much less congested slice of spectrum to use — especially valuable as a clean, fast backhaul channel. WiFi 7 expands on this further with multi-link operation, letting devices use multiple bands simultaneously.
The answer is 6 GHz. WiFi 6E was a significant leap because it unlocked the 6 GHz band — a largely empty, high-capacity range of spectrum that dramatically reduces interference, especially in apartment buildings packed with competing networks. Mesh systems use it as a super-clean backhaul highway.
Before dedicated mesh systems existed, some creative users built their own mesh-like home networks using open-source firmware called what?
Well done! DD-WRT was the go-to open-source router firmware for enthusiasts who wanted to squeeze extra performance and features out of consumer routers — including running multiple routers in coordinated configurations that resembled mesh behavior. It’s still actively developed today and has a devoted following.
Not quite — the answer is DD-WRT. This legendary open-source firmware let tech-savvy users replace the factory software on routers from brands like Linksys and Netgear, unlocking advanced features including multi-router setups that approximated mesh networking years before polished consumer mesh products existed.
Which emerging concept would take mesh networking beyond the home and create a massive, self-organizing internet built from billions of everyday devices?
Exactly right! The Internet of Things vision includes smart devices — thermostats, lights, sensors, appliances — forming spontaneous mesh networks with each other, passing data along without relying on a central router or ISP infrastructure. Standards like Thread and Matter are already pushing this concept into real homes today.
The answer is the IoT mesh. The Internet of Things roadmap envisions billions of smart devices forming organic, self-organizing mesh networks — communicating peer-to-peer without needing a traditional router as a middleman. Protocols like Thread (used in Matter-compatible smart home devices) are making this a reality right now.
What quirky real-world project demonstrated mesh networking by connecting an entire island community with a DIY WiFi mesh built mostly from recycled hardware?
Correct! Guifi.net, launched in rural Catalonia in the early 2000s, grew into one of the world’s largest community-owned mesh networks with tens of thousands of nodes. It was built by volunteers using cheap or recycled hardware to bring internet access to areas ignored by commercial ISPs — a remarkable grassroots achievement still operating today.
The answer is Guifi.net. This incredible volunteer-built mesh network in Catalonia, Spain, started in the early 2000s and eventually grew to over 35,000 active nodes, making it one of the largest community mesh networks on the planet. It proved that determined communities could build their own internet infrastructure without relying on big telecoms.

Multi-gig networking is more than just a faster outside connection
I’m all about that LAN
While a faster external connection might not make a lot of sense, having a multi-gig LAN definitely does. Just over a year ago, I upgraded my own local network from gigabit to 2.5Gb/s and it changed everything for me.
While an external server, like Steam, might limit you with a multi-gig connection, you can actually build your own internal systems to fully saturate just about any networking standard you choose to use. You see, chances are, those Steam servers could serve files at multi-gig speeds, but their own internet connection is likely the limiting factor.
Since you’re the one building your own networking infrastructure, it’s very easy to make sure that every device in the network has multi-gig capabilities. For me, that means having a multi-gig switch and network cards in all necessary devices. SSDs definitely can hit multi-gig speeds, and most RAID arrays are also capable of that type of speed for file transfers.
Building out a multi-gig network is about way more than just a faster outside connection—it’s all about the internal connection your systems have. Plus, by setting up a multi-gig local network first, you’re preparing yourself for the inevitable upgrade to a multi-gig internet connection.
Faster NAS access is life-changing
If your life revolves around computers, at least
So, how did a multi-gig local network change everything for me? Well, it removed some bottlenecks that I was experiencing in my own homelab. For example, on standard gigabit, file transfers from my desktop or laptop to my NAS would take forever. Sometimes I would actually avoid doing a network file transfer because of how slow it would be. Instead, I’d just grab an external SSD or flash drive and move the files to that because it was faster.
This became a problem, because I wasn’t actually using my NAS as a NAS—it simply was just a Plex server and nothing more. That’s fine and all, but I deal with a lot of data and really need to keep a lot of it backed up, which is something I simply wasn’t doing.
Moving my network from gigabit to 2.5Gb/s meant I could transfer data at 2.5x the speed that I used to. That might not sound like a ton, but a file transfer that used to take 10 minutes now takes just 4. A one hour transfer takes just 24 minutes now.
By going multi-gig on my LAN, I also opened up my NAS to more than just archive file storage. Now, I store active video and photo projects on it and work directly from my NAS on my computer. This allows me to keep my laptop’s storage optimized and keep the big working files on the NAS where they belong.
Another benefit to a multi-gig LAN is that the servers can talk to each other faster than they could before. I have my movie and TV shows stored on my big 12-bay rack-mount server, but the system that actually runs Plex is another computer that has way more processing and transcoding power. That means my Plex media is being read over the network, and having the extra bandwidth of a multi-gig connection ensures I won’t have any stuttering or buffering issues with the media.

A multi-gig network just makes your homelab easier to use
At the end of the day, a multi-gig network simplifies so much in a homelab. It makes file transfers faster, which makes it feel more seamless. It allows servers to communicate at faster rates, which can help reduce buffering or backup times.
However, a multi-gig internet connection doesn’t really improve a whole lot. Sure, it helps make a few things faster to download, but, it’s not nearly as beneficial as it might sound. I just don’t see the need to pay the extra for a multi-gig internet connection right now. A few years from now it might make sense, but, in 2026, there’s not enough multi-gig servers serving up files for multi-gig internet to make a ton of sense.
