Abstract
- Older routers can pose safety dangers resulting from an absence of updates, in addition to outdated safety protocols. Hackers are at all times trying 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 that you must improve sooner quite than later.
- Many models do not help trendy good house requirements like Matter and Thread, that are more and more de facto. That is going to rely for those who’re constructing or increasing your house configuration.
A reminiscence that is oddly caught in my mind is looking for a Wi-Fi router early after shifting to Austin. I did not wish to spend a lot, since I wasn’t making a lot cash on the time, and shifting internationally was already tremendously pricey. However even then, I knew that a number of the routers on the cabinets had been clearly outdated and a nasty deal.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 record, there’s extra happening than bandwidth. Wi-Fi routers are inclined to type the spine of your digital life, a minimum of 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 danger of safety vulnerabilities
Help would not final eternally
One primary concern is that the older a router is, the much less seemingly it’s to obtain software program updates. Any first rate {hardware} ought to get updates for a minimum of three to 5 years, and probably longer — nevertheless it’s vital to examine, since unpatched flaws may doubtlessly 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 word, all routers are depending on an assortment of safety protocols, that are periodically overhauled to be extra resilient. Gadgets that do not help the most recent protocols are inherently extra open to assault. The excellent news right here is that a very powerful one — WPA3 — has been obtainable since 2018, and obligatory for Wi-Fi certification since 2020, so that you’re unlikely to be uncovered until you are unboxing an outdated 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 at all times higher to futureproof
Eero
Essentially the most superior variations of Wi-Fi at all times value further, all different options being equal. Wi-Fi 7 is dearer than 6E, as an illustration, which in flip is dearer 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 adequate for a house with 4K TVs, gaming techniques, and good house equipment.
You most likely needn’t put money into state-of-the-air expertise, however going a notch (or two) over the baseline will preserve your router related for longer.
“Enough” is the operative phrase, although. An outdated router can rapidly really feel like a relic if it would not maximize your units’ bandwidth. Many routers do not even totally exploit the usual they’re based mostly on, so there could possibly 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 preserve your router related for longer. That may really get monetary savings over time.

Help for the most recent good house requirements
Matter issues
CSA/Pocket-lint
Newer routers usually tend to work with two key good house requirements: Matter and Thread. Matter is a protocol that allows common pairing for equipment, as a substitute of requiring them to help requirements like Amazon Alexa, Apple HomeKit, or Google House 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 case you’re not conversant in good house 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 depart your house operating easily. A couple of corporations, like Philips Hue, could also be clinging onto Zigbee for the second — however I might wager on their gear gaining Thread help within the subsequent two or three years.

Ethernet and USB ports might 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 a giant deal. Router makers had principally settled on gigabit Ethernet, because it was greater than sufficient for the typical modem connection (WAN) and plenty of local-area (LAN) units. As for USB, 2.0 and three.0 speeds had been sufficient for issues like network-attached printers, and possibly 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 case you join, 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 case 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 for those who’re fortunate sufficient to come across one, 3.1 or sooner is clearly preferable. USB-C is equally uncommon, a minimum of exterior of energy sources, however I might count on that to alter. Prices are coming down, and it is arduous to disregard the format’s measurement, comfort, and rising prevalence amongst shopper electronics. Nobody ought to want an adapter cable simply to hook up an SSD filled with music and films.
