Ever puzzled what the USB-A port on the again of your Wi-Fi router is for? A number of issues, relying on the mannequin. For instance, the port on the Asus RT-BE86U router can be utilized for primary file sharing throughout your community, charging small units, and as a waypoint for backing up your pc to an exterior drive.
However here is the reality: I do not suggest utilizing it. Having a USB port on the router sounds handy, however there are just a few issues.
Additionally: The right way to run an internet speed tests (and how to use the results for faster Wi-Fi)
The very fact is that USB ports on routers aren’t safe. Lots of them function on outdated protocols, creating vulnerabilities that may be exploited by unhealthy actors. This doesn’t suggest your complete router is compromised, however the USB port could be a weak hyperlink. Utilizing it’s not a danger value taking, particularly when safer options can be found.
Let’s break down the largest causes it’s best to keep away from utilizing the USB port in your router and what to do as a substitute.
1. It is a safety danger
Once I say “outdated protocols”, I’m largely referring to FTP or File Switch Protocol. It is an previous protocol from the Seventies that does not use any type of encryption; even transmitting passwords in plain textual content. FTP has been extensively changed by the HTTPS protocol, however even current routers, just like the Asus RT-BE86U, have ports that use it.
As Progress Software factors out, a nasty actor might simply take these credentials with the precise technical know-how, even probably having access to your community.
Additionally: Should you upgrade your traditional Wi-Fi router to mesh? I compared the two, and here’s my take
One other one to be careful for is SMBv1 (Server Message Block model 1). It is one other file-sharing protocol that was notably exploited by the WannaCry ransomware in 2017, infecting a whole bunch of hundreds of methods worldwide.
Microsoft has been urging firms and IT professionals to disable the legacy protocols — and their utilization has certainly dropped — however they nonetheless exist on units in folks’s properties. Add the truth that malware turns into extra refined yr after yr, and it is too dangerous to depend on these protocols for file switch over a router.
2. It is unreliable
That is going to sound apparent, however the main objective of a router is to determine and handle a wi-fi community. That is what the {hardware} and software program are optimized for. It is when as soon as a router deviates from its main objective, that the standard of the know-how deteriorates.

Most shopper fashions do not have the processing energy to deal with each their regular networking duties and file transfers concurrently. When the router is juggling a number of workloads, you could encounter:

- Latency spikes
- Connection drops
- File switch failures
That final entry can are available a number of varieties. It is attainable that solely a part of the file will switch, that it will get dropped, or worse, corrupted. To make sure that connections keep secure, keep away from utilizing the USB port, particularly when you personal an older router.

Articles from as far back as 2013 level out that the USB 3.0 normal interferes with 2.4 GHz Wi-Fi alerts. Expertise has improved dramatically since then, however it’s nonetheless one thing to be aware of.
One other potential problem is overheating. The added electrical load places additional pressure on the {hardware}, rising inside temperatures, which might then lead to efficiency throttling. Excessive warmth does not simply have an effect on the router within the second; it may additionally shorten the system’s lifespan.
What I like to recommend as a substitute
If you’d like dependable file sharing and media storage for your own home, there are far safer and higher options.
Purchase a NAS
Your best choice is to spend money on a NAS (Community-Connected Storage), which is basically a mini server in your dwelling. Whereas an exterior {hardware} drive can do one thing comparable, a NAS gives one main benefit: sturdy information safety.
NAS units generally help AES-256 encryption to safeguard delicate information and information. Many fashions additionally help RAID (Redundant Array of Unbiased Disks). This know-how distributes information throughout a number of NAS drives, guaranteeing your information stay secure even when one of many drives fails unexpectedly.
Additionally: Looking for a capable NAS? Here’s one I recommend (but it’s not for beginners)
If you happen to’re , I extremely suggest testing ZDNET’s listing of the best network-attached storage devices you can buy.

For a extra budget-friendly possibility, the QNAP TS-233-US 2-Bay is your most suitable option.
Put money into cloud storage
One other good different is to make use of cloud storage somewhat than counting on native drives. These platforms securely retailer information, images, and movies on-line, making them accessible on nearly any system with an web connection. Even higher: most suppliers have free storage plans.
Google has top-of-the-line, giving customers 15GB without charge, whereas Apple’s iCloud and Microsoft’s OneDrive every present 5GB of house. As nice as these plans are, they replenish rapidly. All three provide paid subscriptions that develop your obtainable house.
Additionally: Which cloud storage service should you buy in 2025? I compared the best options, and here’s my pick

Whereas many of those companies ship the storage they promise, they elevate numerous purple flags. You may discover many discussion board posts questioning the legitimacy and security of those companies, so I urge warning.
The right way to use the the USB port safely
If you happen to insist on utilizing your router’s USB port, there are two vital precautions to comply with. First, solely use it for non-critical information. Do not share or switch something delicate by way of the port. Persist with low-risk content material, corresponding to motion pictures you wish to share with others in your family.
Secondly, set up firmware updates as quickly as they turn into obtainable to patch up any safety points and keep stability. That is assuming your router remains to be receiving updates. Router producers will drop help for older fashions. In case your system is now not supported, try my listing of the five products I recommend to improve your Wi-Fi.
I’ve spent almost a decade reviewing {hardware}, software program, and varied sorts of shopper tech — together with Wi-Fi routers. As a part of my work, I push routers to their limits in an effort to see in the event that they’re value recommending. I take note of any modifications in pace which will happen, in addition to be taught what they’ll or cannot deal with. Typically a characteristic, corresponding to a USB port, might appear to be it will come in useful, however in follow, it is not value utilizing on account of key flaws.

I then share these findings so you may keep away from the pitfalls that I found or bumped into.

My aim is to supply steering rooted in actual testing, so you may make sensible decisions in your dwelling community. I additionally goal to foster the boldness to handle your community successfully.
