My HP gaming laptop computer comes with a devoted Ethernet port, which is what I favor over Wi-Fi at any time when it is accessible. However my Asus Vivobook Flip would not have one. It traded an important port for a slim profile, so I acquired an inexpensive USB-to-Ethernet adapter so as to add the lacking port.
Whereas the Ethernet adapter fastened the plain drawback, I’ve since discovered extra use circumstances for it, ones that solved issues I did not even know I had. In the event you’ve been working a homelab or self-hosting services on hardware you already own, you will see what I imply.
Further Ethernet port for backup connection
A second NIC retains my self-hosted companies on-line throughout outages
My ISP is fairly dependable for probably the most half and infrequently takes care of occasional downtime in a few hours. However I self-host a variety of issues for the household, from file storage to password vaults, so even a brief outage will be annoying when somebody wants entry to one thing proper now.
I’ve a backup connection from a secondary ISP, and the TP-Link UE300C lets me plug it into my server as a second community interface. When the first connection goes down, the failover kicks in, and my companies keep accessible with out me having to the touch something.
It is not one thing I deliberate once I purchased the adapter. However as soon as I noticed I might give a single machine two separate community paths for about $10, it turned one of many extra helpful purchases I’ve made this yr. In the event you run any sort of dwelling server or self-hosted setup with a backup line, a second NIC by USB is the most cost effective option to make failover work.
Giving my skinny and light-weight laptop computer a pace enhance
Wired connections repair what Wi-Fi retains breaking
Now the actual purpose I purchased the Ethernet adapter within the first place: to provide my skinny and light-weight laptop computer a wired connection. My Asus Vivobook S 14 Flip is a succesful system and may do all kinds of gymnastics, nevertheless it lacks a devoted Ethernet port, forcing me to depend on wi-fi networks for every little thing.
This turns into an even bigger situation once I’m touring and must take care of congested wi-fi networks in resort rooms. With a USB-to-Ethernet adapter, I can skip Wi-Fi solely, plug in an Ethernet cable wherever it is accessible, and the pace complaints normally cease. Accommodations, convention facilities, and co-working areas nearly at all times have Ethernet jacks someplace, and a wired connection avoids the mess of dozens of units combating for a similar wi-fi channel.
Ethernet adapters can be found for each USB Sort-A and Sort-C ports. I went with a Sort-C model because it additionally works with my cellphone, simply in case I ever wanted a wired connection on cell.
Homelab router builds from previous PCs or NUCs
A USB adapter turns a single-NIC machine right into a two-port router
In case you have an previous PC or a NUC accumulating mud, there is a good probability it solely has one Ethernet port. That is high-quality for a desktop, however if you wish to repurpose it right into a router or firewall working one thing like OpenWRT or OPNsense, you want two community interfaces: one for the WAN aspect (your web connection) and one for the LAN aspect (your change or entry level).
Opening the case and including a PCIe NIC is one possibility, however not each machine has a free slot, and a few NUCs do not even have that possibility. A USB-to-Ethernet adapter solves this for a couple of {dollars}. Plug it in, assign one interface to WAN and the opposite to LAN, and you’ve got a practical two-port router with out cracking the case open.
Whereas this works for lighter dwelling setups, be certain the adapter you choose helps PXE boot in case you plan in addition over the community, as a result of not all of them do. For something mission-critical or high-throughput, a correct PCIe NIC continues to be the higher name. However for a weekend homelab router challenge, USB Ethernet will get the job finished.
Raspberry Pi clusters
A second NIC per node retains storage site visitors off the principle community
This one is extra area of interest, however in case you’re working a Raspberry Pi (Pi 4 or older) cluster, USB-to-Ethernet adapters open up a genuinely helpful trick. The Pi would not have a PCIe slot or an M.2 enlargement, so there is not any means so as to add a second community interface with out going by USB.
The thought is to make use of the Pi’s onboard NIC for PXE boot and common service site visitors, and dedicate the USB Ethernet adapter to iSCSI storage or NFS mounts. That means, heavy storage I/O would not compete with the companies working on the identical machine. In the event you’re working one thing write-heavy or I/O-intensive, this cut up could make a noticeable distinction in how responsive your containers keep.
It is also a sensible option to keep away from microSD playing cards for storage-heavy workloads, since these have a tendency to wear down quick below fixed writes. The TP-Hyperlink UE300 collection works effectively right here as a result of the drivers are already baked into the Linux kernel, so there is not any fussing with handbook set up. Simply plug it in, and it is able to go.
Boosting Android TV community pace
Your TV’s Ethernet port might be slower than you assume
Most sensible TVs, even costly ones, include a ten/100 Ethernet port that caps out at 100 Mbps. In the meantime, the identical TV typically has Wi-Fi 5 or Wi-Fi 6, which might simply push previous that quantity. So in a variety of circumstances, your TV’s Ethernet port is slower than its own Wi-Fi.
For normal streaming, 100 Mbps is okay. Netflix, YouTube, and Disney Plus do not want anyplace close to that, even for 4K. However in case you’re streaming domestically from a NAS, taking part in Blu-ray remuxes by Plex or Jellyfin, or utilizing sport streaming instruments like Steam Hyperlink or Moonlight, a 4K HEVC file with Dolby Imaginative and prescient and lossless audio can simply blow previous 100 Mbps in sustained bitrate. That is the place the built-in port turns into a bottleneck.
A USB-to-Ethernet adapter with a Gigabit controller bypasses your smart TV’s Ethernet limit entirely. The adapter has its personal networking chip, so it would not depend on the TV’s built-in Ethernet controller in any respect. Plug it right into a USB 3.0 port in your TV, join an Ethernet cable, and you will get speeds effectively past the 100 Mbps ceiling. Compatibility varies by TV mannequin and model, although, so it is value checking whether or not your particular TV acknowledges USB Ethernet adapters before you purchase one.

It will not change an actual NIC, nevertheless it would not must
For all these use circumstances, there’s one caveat value mentioning. USB-to-Ethernet adapters are usually seen as much less dependable than a correct PCIe NIC. They’ll battle below heavy, fixed load, like the sort you’d placed on a NAS, a Proxmox host, or a manufacturing firewall. They could not at all times hit full Gigabit speeds, and a few have points waking from sleep or reconnecting after the host machine reboots.
That is high-quality, as a result of they do not must be bulletproof. For laptops, non permanent setups, Raspberry Pi clusters, and low-power dwelling tasks, they’re greater than sufficient. I maintain one completely in my laptop computer bag and one other plugged into my dwelling server for failover. At $10, the price of making an attempt is so low that the worst final result is discovering one other use for it you hadn’t thought-about. Simply do not plan your total server infrastructure round them, they usually’ll serve you effectively.
