How to Switch From 5GHz to 2.4GHz Wi-Fi on Any Device: Step-by-Step

Here’s something that trips up a lot of people. When you search “how to switch from 5G to 2.4G Wi-Fi,” you’re almost certainly not talking about mobile 5G networks. 

You mean the 5GHz band on your home router. Completely understandable, the naming is genuinely confusing, and nobody really explains the difference upfront. 

What usually brings someone here is a smart device that won’t connect. A plug. A bulb. A doorbell camera. Everything looks fine (Wi-Fi’s on, phone’s connected, app is open), but the thing just won’t pair. 

The most common culprit is a band mismatch: the gadget wants 2.4GHz and your router’s handing out 5GHz instead. 

This guide covers exactly how to fix that on every major device type. 

What’s the Difference Between 2.4GHz and 5GHz Wi-Fi? 

The short version: 2.4GHz travels further, whereas 5GHz moves faster. 

That’s not marketing shorthand, it’s physics: 

• The lower the frequency, the better it penetrates walls and travels across distances. 
• The higher the frequency, the more data it can carry, but the shorter its effective range. 

Here’s a practical breakdown: 

The First Thing to Check: Your Router, Not Your Phone 

Most people go straight to their phone settings. That instinct is wrong, and it costs them 20 minutes of pointless tapping. 

The real answer almost always lives inside the router. 

If your router only shows one Wi-Fi name, it’s almost certainly using Smart Connect (also called band steering). This is a feature where the router decides which band each device gets, and it doesn’t always get it right. 

Your phone might land on 5GHz during a smart-home setup because the signal is strong, even though the device you’re pairing is on 2.4GHz. 

In that situation, you’ve got three options: 

• Temporarily disable Smart Connect or 5GHz during device setup 
• Log in to your router settings and split the bands into two separate network names 
• Move the smart device and your phone physically closer to the router during pairing. Sometimes, this alone convinces the router to serve 2.4GHz 

How to Switch to 2.4GHz on iPhone and iPad? 

Switching to 2.4GHz on an iPhone is straightforward, if your router cooperates. 

• Look for the 2.4GHz version of your network name (usually labelled with “2.4” or without a “5G” suffix) 
• Go to Settings → Wi-Fi 
• Tap it and connect 

That’s the whole process when bands are split. 

If your router only shows one network name, iOS gives you no way to force a specific band. The iPhone selects the band based on signal quality and device history. There’s no hidden toggle; Apple doesn’t expose that level of Wi-Fi control to users. 

Here’s a real-world scenario we see a lot: someone in a Manchester terrace house is setting up a TP-Link Tapo smart plug in the kitchen. 

Their iPhone is sitting on 5GHz (solid signal, fast connection, all makes sense). The Tapo plug only supports 2.4GHz. The app keeps failing at the “connecting to device” screen. 

Nothing appears broken. The fix? Either split the router bands or temporarily disable 5GHz in the router admin panel, usually accessible at 192.168.1.1 or 192.168.0.1, depending on the model. 

How to Switch to 2.4GHz on Android? 

The process on Android is nearly identical to iOS. 

• Find the 2.4GHz network name 
• Open Settings → Network & Internet → Wi-Fi (exact path varies slightly by manufacturer) 
• Tap to connect 

Some Android phones (particularly Samsung devices running One UI) will show signal strength icons that give you a rough sense of which network is which, but they don’t explicitly label the band in the standard Wi-Fi list. 

If the router only shows one name, Android faces the same limitation as iPhone: it can’t force 2.4GHz on its own. The decision sits with the router. 

That said, some Android devices do offer a hidden developer option to lock Wi-Fi frequency bands. But this varies by model, requires enabling Developer Mode, and isn’t worth the hassle for most people. Sorting it at the router level is cleaner. 

How to Switch to 2.4GHz on Windows? 

Windows makes this slightly more manageable than phones, not dramatically, but a bit. 

• Select the 2.4GHz network name from the list 
• Click the Wi-Fi icon in the taskbar (bottom right) 
• Click Connect 

If you want Windows to prefer 2.4GHz on a dual-band router that uses a single name, you can adjust the adapter settings: 

• Right-click → Properties → Advanced 
• Open Device Manager 
• Expand Network Adapters and find your Wi-Fi adapter 
• Look for Preferred Band or Band Preference and set it to 2.4GHz 

Not all adapters show this option. But it’s worth checking before you go into the router. 

How to Switch to 2.4GHz on Mac? 

On a Mac, the process is clean: 

• Click the Wi-Fi icon in the menu bar (top right) 
•  Select the 2.4GHz network name 
• Enter the password if prompted 

macOS doesn’t give you a native band-preference option beyond manually choosing the network. So again, if the router only shows one name, the workaround is at the router level, not the Mac. 

One thing macOS does well: it remembers your preferred network. If you’ve split your bands and connected your Mac to the 2.4GHz one, it’ll keep connecting to that one automatically. 

Helpful if you’re setting up a smart-home kit and need your laptop to stay on the same band as the device during configuration. 

Why 2.4GHz Matters So Much when Setting Up Smart-Home Devices? 

Most smart-home devices sold in the UK only support 2.4GHz. 

Not because they’re outdated, but because 2.4GHz is genuinely more practical for low-bandwidth, always-on devices that need a stable range rather than raw speed. 

A smart thermostat sending a temperature reading every few minutes doesn’t need fast Wi-Fi. It needs reliable Wi-Fi that reaches the hallway. 

Based on what users typically encounter during smart-home setup, the single biggest cause of failed pairing isn’t the app, the device, or the phone. 

The fastest fix for any smart-home pairing issue: 

• Complete the device pairing on 2.4GHz 
• If not, log into your router admin (usually 192.168.1.1 or via your ISP’s app — BT Smart Hub, Sky Hub, Virgin Hub, etc., all have companion apps) 
• Check whether your router broadcasts separate 2.4GHz and 5GHz names 
• Either split the bands or temporarily disable 5GHz 
• Re-enable 5GHz once it’s done 

The whole process takes about five minutes once you know what you’re doing. 

When 5GHz Is the Better Choice 

Don’t switch to 2.4GHz as a default. For most everyday use, 5GHz outperforms it significantly. 

Stick with 5GHz when: 

• You’re streaming 4K content on BBC iPlayer, Netflix, or Disney+ 
• You’re gaming online and need low latency 
• Your device is in the same room or close to the router 
• You’re on a video call and want a stable, fast connection 

Switch to 2.4GHz when: 

• A device won’t connect on 5GHz (especially a smart-home kit) 
• You’re in a room where the 5GHz signal is weak 
• The device’s manual specifically states 2.4GHz only 

Neither band is universally “better.” It depends entirely on what you’re doing and where you are in the building. 

Wrapping It Up 

To wrap up, sorting your router bands usually fixes the problem. But there are plenty of moments — a new property, a broadband outage, a router reset that wipes your settings — when home Wi-Fi becomes genuinely unreliable for a stretch. 

That’s where having solid mobile data as a backup is nice to have. 

Talk Home Mobile plans are built for exactly this kind of flexibility. If your broadband is down while you’re mid-setup on a smart device, or you’re working from a new flat waiting for the engineer, Talk Home Mobile keeps you connected without locking you into anything long-term.
