Abstract
- Older routers can pose safety dangers resulting from an absence of updates, in addition to outdated safety protocols. Hackers are all the time seeking to exploit unpatched vulnerabilities.
- Routers with simply sufficient bandwidth can hobble your units, and may very well value you extra in the long term if it’s good to improve sooner moderately than later.
- Many models do not help fashionable sensible residence requirements like Matter and Thread, that are more and more de facto. That is going to depend in case you’re constructing or increasing your house configuration.
A reminiscence that is oddly caught in my mind is searching for a Wi-Fi router early after transferring to Austin. I did not need to spend a lot, since I wasn’t making a lot cash on the time, and transferring internationally was already tremendously pricey. However even then, I knew that a few of the routers on the cabinets had been clearly outdated and a foul deal. I bit the bullet and spent simply sufficient to keep away from any main downsides.
What downsides had been at play, you ask? I am going to clarify in a second after all, however simply to preface this listing, there’s extra occurring than bandwidth. Wi-Fi routers are likely to kind the spine of your digital life, no less than in your house — so any deficiency can have outsized penalties. It is arguably extra vital to put money into Wi-Fi than in smart lights and even your thermostat.

4 reasons I’m not upgrading to Wi-Fi 7 (at least not yet)
Simply because the tech is prepared does not imply you want it straight away, or that you will even profit.

The chance of safety vulnerabilities
Help would not final without end
One primary concern is that the older a router is, the much less possible it’s to obtain software program updates. Any first rate {hardware} ought to get updates for no less than three to 5 years, and probably longer — however it’s vital to examine, since unpatched flaws might probably be exploited by hackers. The antivirus software program in your telephones, computer systems, and different units is supposed to be the final line of protection for stopping threats, not the primary.
The antivirus software program in your telephones, computer systems, and different units is supposed to be the final line of protection for stopping threats, not the primary.
On a associated be aware, all routers are depending on an assortment of safety protocols, that are periodically overhauled to be extra resilient. Units that do not help the newest protocols are inherently extra open to assault. The excellent news right here is that crucial one — WPA3 — has been out there since 2018, and necessary for Wi-Fi certification since 2020, so that you’re unlikely to be uncovered except you are unboxing an previous router out of your storage room.
Some routers could include further safety instruments, however these are often only a perk. Once you’re purchasing, deal with protocols and updates earlier than anything.

The bandwidth downside
It is all the time higher to futureproof
Eero
Essentially the most superior variations of Wi-Fi all the time value further, all different options being equal. Wi-Fi 7 is costlier than 6E, as an illustration, which in flip is costlier than Wi-Fi 6. As a consequence, it may be fairly tempting to go together with the bottom spec that meets your necessities. Wi-Fi 6 routers are hardly horrible, the truth is — they’re nonetheless enough for a house with 4K TVs, gaming techniques, and sensible residence equipment.
You most likely needn’t put money into state-of-the-air expertise, however going a notch (or two) over the baseline will hold your router related for longer.
“Adequate” is the operative phrase, although. An previous router can rapidly really feel like a relic if it would not maximize your units’ bandwidth. Many routers do not even absolutely exploit the usual they’re primarily based on, so there may very well be an enormous gulf between a low-end Wi-Fi 6 router and one thing like my Eero Professional 6E, by no means thoughts a business-level Wi-Fi system.
You most likely needn’t put money into state-of-the-air expertise, however going a notch (or two) over the baseline will hold your router related for longer. That may truly lower your expenses over time.

Help for the newest sensible residence requirements
Matter issues
CSA/Pocket-lint
Newer routers usually tend to work with two key sensible residence requirements: Matter and Thread. Matter is a protocol that permits common pairing for equipment, as an alternative of requiring them to help requirements like Amazon Alexa, Apple HomeKit, or Google Residence out of the field. Thread, in the meantime, is a low-power mesh protocol for merchandise like bulbs, switches, and sensors that is changing requirements like Z-Wave and Zigbee.
In the event you’re not accustomed to sensible residence tech, or have already got a working setup, you may not care for the time being. However as I hinted, Matter and Thread are more and more changing into de facto, and a system with further Matter controllers and Thread border routers is inherently extra steady — it means one can go down and go away your house working easily. A number of corporations, like Philips Hue, could also be clinging onto Zigbee for the second — however I might guess on their gear gaining Thread help within the subsequent two or three years.

Ethernet and USB ports will not be as much as snuff
Do not pay for multi-gig web with out studying this primary
DanYee / Pocket-lint
For a short time, the efficiency of Ethernet and USB ports on a shopper router wasn’t an enormous deal. Router makers had largely settled on gigabit Ethernet, because it was greater than sufficient for the typical modem connection (WAN) and lots of local-area (LAN) units. As for USB, 2.0 and three.0 speeds had been sufficient for issues like network-attached printers, and perhaps some low-demand file servers.
Your router must have a WAN connection to match the bandwidth in your web plan.
Now, although, gigabit web is more and more commonplace, and some web service suppliers are promoting multi-gigabit plans. In the event you enroll, your router must have a WAN connection to match — a 2-gigabit plan calls for a 2.5Gbps Ethernet port and cable, for instance. In the event you’re rolling in money, chances are you’ll even want 10Gbps Ethernet, although at that time you are most likely going to be shopping for a top-of-the-line Wi-Fi 7 router anyway.
With USB, chances are you’ll not want something greater than a 3.0 port — however in case you’re fortunate sufficient to come across one, 3.1 or sooner is clearly preferable. USB-C is equally uncommon, no less than outdoors of energy sources, however I might anticipate that to alter. Prices are coming down, and it is onerous to disregard the format’s dimension, comfort, and rising prevalence amongst shopper electronics. Nobody ought to want an adapter cable simply to hook up an SSD stuffed with music and films.
