Your New Router Is Blazing Fast — Too Bad Half Your Devices Can't Tell the Difference
So you finally did it. You retired that dusty old router, spent real money on something with WiFi 6 stamped on the box, and waited for the internet to feel like a rocket ship. Instead, it feels... pretty much the same. Maybe a little better. Maybe not even that.
Before you fire off a complaint to your ISP or haul the router back to Best Buy, take a breath. The culprit probably isn't your new hardware. It's almost certainly everything connecting to it.
The Part Nobody Tells You at the Register
WiFi 6 (technically called 802.11ax) is genuinely impressive technology. It handles multiple devices more efficiently, reduces congestion on crowded networks, and can push dramatically higher speeds to compatible hardware. The keyword there is compatible.
Your router broadcasts on WiFi 6, but every device that connects to it has to speak that same language to benefit from it. If your laptop was bought in 2018, your smart TV came with the house, or your kid's tablet was a birthday gift three years ago, there's a very real chance those devices are still running on WiFi 5 (802.11ac) or even older WiFi 4 (802.11n) radios. They'll connect to your new router just fine — they just won't get anywhere near its full potential.
It's a little like upgrading to a 10-lane highway when most of your cars only have engines built for a two-lane road.
How to Actually Check What Your Devices Support
This is easier than most people think, and it doesn't require any special software.
On Windows: Go to Settings > Network & Internet > WiFi, click on your current connection, and scroll down to find "Protocol." You'll see something like Wi-Fi 6 (802.11ax) if you're in good shape, or Wi-Fi 5 (802.11ac) if you're not.
On a Mac: Hold down the Option key and click the WiFi icon in the menu bar. Look for "PHY Mode" — it'll list your current WiFi standard right there.
On Android: It varies by manufacturer, but most phones running Android 10 or later show WiFi details under Settings > Network > WiFi > your connected network. Some will show the protocol, others just show the frequency band.
On iPhone: Apple doesn't expose this natively, but you can check your phone's model specs on Apple's website. iPhones from the iPhone 12 onward support WiFi 6. Anything before that tops out at WiFi 5.
For smart TVs and other devices: Check the manufacturer's spec page for your exact model. Search the model number plus "WiFi specs" and look for the 802.11 standard listed under connectivity.
Go room by room and do a quick audit. You might be surprised how many devices in your home are still running on standards that were current during the Obama administration.
Does Upgrading Actually Make Financial Sense?
Here's where we have to get honest with you: not always.
If your main bottleneck is a laptop you use eight hours a day for video calls and large file transfers, upgrading to a WiFi 6 capable machine — or even adding a USB WiFi 6 adapter for around $30 to $50 — could make a noticeable difference in your day-to-day experience.
But if we're talking about a smart thermostat or a WiFi-connected light bulb? Those devices pull so little bandwidth that WiFi 4 is more than sufficient. Upgrading them for speed reasons would be a waste of money.
The devices worth prioritizing for a WiFi standard upgrade, in rough order of impact:
- Your primary laptop or desktop — especially if you work from home
- Your main streaming device — 4K HDR content is bandwidth-hungry, and a WiFi 6 capable streaming stick or TV makes a real difference
- Gaming consoles — the PS5 and Xbox Series X both support WiFi 6, but older consoles don't; if you're still on a PS4 or Xbox One, this is worth noting
- Smartphones — most flagship phones from 2020 onward support WiFi 6; if your daily driver is older than that, a new phone will bring network benefits along with everything else
- Smart home hubs — if you have a lot of connected devices running through a central hub, upgrading that hub can improve the whole ecosystem
The 2.4 GHz vs. 5 GHz Wrinkle
While you're doing this audit, it's worth checking something else: which frequency band your devices are actually connecting on. WiFi 6 routers broadcast on both 2.4 GHz and 5 GHz bands (and WiFi 6E adds 6 GHz). The 5 GHz band is faster but has shorter range. The 2.4 GHz band travels farther but gets more congested.
Older devices often default to 2.4 GHz out of habit or because that's all they support. If your relatively modern laptop is connecting on 2.4 GHz when it could be on 5 GHz, that's a settings fix, not a hardware problem. Check your device's WiFi settings and manually connect to your router's 5 GHz network if it isn't already.
What to Do Right Now, Without Spending a Dime
Before you start budgeting for new devices, squeeze everything you can out of what you already own:
- Update your device drivers and firmware. Outdated network drivers on a Windows laptop can cap performance even on capable hardware.
- Forget and rejoin your WiFi network. This forces your device to renegotiate its connection and sometimes bumps it to a better band or channel.
- Move closer to your router for devices where that's practical. Distance and walls affect WiFi 5 and WiFi 4 devices more harshly than WiFi 6.
- Check if your router has a "band steering" feature that automatically moves capable devices to faster bands. Enable it if it's available.
The Bigger Picture
A WiFi 6 router is a solid investment — but it's the beginning of a transition, not an instant transformation. The full benefits reveal themselves gradually as your older devices get replaced through the normal upgrade cycle. You don't need to go out and swap every gadget in your house next weekend.
What you should do is go in with clear eyes. Know which devices are actually limiting your experience, understand where spending money makes sense, and stop blaming your router for a problem it isn't causing. Your signal is only as powerful as the devices that can actually receive it.
And now, at least, you know exactly where to look.
