Introduction

For many homes and offices, Wi-Fi coverage can feel like a never ending game of trying to find that one sweet spot where the connection actually holds. Walls, floors, appliances, and even other nearby networks can all interfere with your signal. One of the most overlooked ways to improve this is by changing the frequency band your router uses.

This is exactly what brings most people to ask the question: How to Change Wifi Hertz? The answer is not as complicated as it may seem, but it does depend heavily on the type of router you have, the device you are using, and your goal for doing it. For many, the goal is simply better range throughout the home. For others, it is to balance speed and coverage for a mix of devices.

In simple terms, when people say “Wifi Hertz”, they are referring to the radio frequency band your Wi-Fi network broadcasts on. The two most common are 2.4 GHz and 5 GHz. Some modern routers also support 6 GHz. Each of these operates on a different range of radio waves, and each comes with its own trade off between range and speed. Knowing when and how to switch between them can make a huge difference for weak signals in far away rooms.

Throughout this guide, you will learn the difference between these frequencies, when to switch, how to change them for most routers, what to do if your router combines bands, and practical tips to get better range without buying a brand new setup right away.

Understanding Wifi Hertz: 2.4 GHz vs 5 GHz vs 6 GHz

Before learning How to Change Wifi Hertz? it is vital to know exactly what is being changed. The “hertz” in this context refers to the frequency band measured in gigahertz, or GHz. These bands are slices of the radio spectrum that your router is allowed to use for wireless communication.

The 2.4 GHz Band

The 2.4 GHz band is the oldest of the widely used consumer Wi-Fi bands. Its biggest strength is its ability to travel farther and pass through solid objects with far less loss than higher bands. This is why it tends to reach garages, basements, back rooms, and other spots far away from your router. The trade off is that it is much more crowded. Bluetooth devices, microwaves, baby monitors, and countless nearby networks all compete for the same space. Speeds are also generally lower, especially if the airwaves are congested.

The 5 GHz Band

The 5 GHz band is much less crowded in most residential areas. With more available channels and wider channel widths, it can reach much higher speeds than 2.4 GHz. However, these higher frequencies do not travel as far and are far more easily blocked by walls, doors, and even large furniture. If you are in the same room as your router, 5 GHz is often the better choice for speed. If you are two or more walls away, you may notice it drop off very quickly.

The 6 GHz Band

6 GHz is the newest band found on Wi-Fi 6E and Wi-Fi 7 routers. It offers an enormous amount of free spectrum with very little congestion at the time of writing. Speeds can be incredibly fast, but range is the shortest out of the three. In most homes, 6 GHz is only practical within a very short distance of the router with a clear line of sight. For the sole purpose of better range, this band is almost never the answer.

Quick Comparison

Feature 2.4 GHz 5 GHz 6 GHz
Range Longest Medium Shortest
Speed Potential Lower Much Higher Highest
Wall Penetration Best Moderate Poor
Congestion Very High Medium Low (for now)
Best Use Long range, smart home, distant rooms Close range, streaming, gaming, large downloads Very close range, ultra fast transfers

Why Change Wifi Hertz For Better Range

The entire reason for learning How to Change Wifi Hertz? comes down to physics. Lower frequencies have longer wavelengths. Longer wavelengths can bend around obstacles and pass through barriers more effectively. Higher frequencies have shorter wavelengths. They carry more data, but they get absorbed and blocked much easier.

If your phone shows full bars next to the router on 5 GHz but drops to one bar or disconnects entirely in your bedroom, switching that device to 2.4 GHz can often bring back a stable, usable connection. You may not get the highest speeds, but for browsing, messaging, and many everyday tasks, stability over range is far more important.

On the flip side, if you are close by and only see weak 2.4 GHz due to congestion, moving to 5 GHz can sometimes appear better despite its shorter theoretical range, simply because there is less traffic. This is why blindly picking a band is not enough. You need to pick based off of distance and obstacles.

Things To Check Before You Try To Change Wifi Hertz

Not every router gives you the ability to manually split or change bands in the same way. Taking a minute to check these things will save you a lot of frustration.

Check Your Router Age And Type

Very old routers may only support 2.4 GHz. Dual-band routers support both 2.4 GHz and 5 GHz. Tri-band routers support 2.4 GHz plus two different 5 GHz networks, or 2.4 GHz, 5 GHz, and 6 GHz. If you only see one network name and your router is very old, you may not have a choice.

Check Your Device Support

Some very old laptops, tablets, or smart devices only support 2.4 GHz. If a device cannot see the 5 GHz network at all, it has no way to connect to it, no matter what you do on the router. Most devices made within the last decade support both bands.

See If The Bands Are Merged

Many newer routers use a feature that combines 2.4 GHz and 5 GHz under one single network name. This is convenient, but it hides the option to manually choose. In that case, you cannot just “flip a switch” for one unified network, you will either need to split them or force your device to connect to the desired band.

Know How You Will Access Settings

You will need access to either the router’s web admin panel from a browser, or the official mobile app for your router. You will also need the login credentials for that panel. These are often found on a label on the router, or in the manual. If they were changed in the past and forgotten, you may need to reset the router as a last resort.

How to Change Wifi Hertz Through The Router Admin Panel

This is the most universal method for learning How to Change Wifi Hertz? and gives you the most control over the frequencies. The exact wording will vary by router, but the steps are nearly identical.

Step 1: Connect To Your Router

  1. Connect your computer or phone to the Wi-Fi network of the router you want to change.
  2. For the most reliable access, use a wired connection if possible. This prevents disconnects while saving settings.

Step 2: Open The Admin Page

  1. Open any web browser.
  2. Type the router’s gateway address into the address bar. Common ones are 192.168.0.1, 192.168.1.1, 192.168.1.254, or 10.0.0.1.
  3. Press enter and you will be taken to the login screen.

Step 3: Log In

  1. Enter your username and password for the router admin panel.
  2. If you have never changed them, try the default credentials from the router label. If changed and unknown, only a full reset will restore defaults.

Step 4: Locate The Wireless Settings

  1. Look for tabs labeled Wireless, Wi-Fi, Network, or Advanced Settings.
  2. For dual-band routers, you will often see two separate sections. One will say 2.4 GHz and another 5 GHz.
  3. For tri-band routers, a third 6 GHz section may appear.

Step 5: Change Or Split The Hertz

  1. To use 2.4 GHz for better range: Ensure the 2.4 GHz wireless network is enabled. You can leave the 5 GHz enabled as well if you want both.
  2. To split merged bands: Find an option called Band Steering, Smart Connect, or Combine 2.4 GHz and 5 GHz. Disable this feature. Once disabled, the router will usually let you give each band a different network name.
  3. To rename for easier choice: Give the 2.4 GHz network a name like Home-WiFi-2G and the 5 GHz network a name like Home-WiFi-5G. This makes it obvious which one you are connecting to.
  4. To adjust channel (optional): Under 2.4 GHz you may see a Channel option. Auto is fine for most, but in very crowded areas manually picking a less used channel can help. Only change this if you understand it, as Auto is safest.

Step 6: Save And Reconnect

  1. Click Apply, Save, or OK at the bottom of the page.
  2. The router may reboot for a moment. This is normal.
  3. On your devices, forget the old network if needed and connect to the band you want based off of distance.

How to Change Wifi Hertz Using A Mobile Router App

Many modern routers now push their management to a mobile app. This is often the easiest way for people who have never touched a router admin page before. The interface is more visual, but it does not always expose every advanced option.

General Steps For Most Apps

  1. Install the official app for your router from your device’s app store.
  2. Log in with your router account or directly to the router while connected to its network.
  3. Navigate to Wi-Fi Settings, Network Settings, or My Network.
  4. Look for Band Settings, Advanced Wi-Fi, or 2.4 GHz / 5 GHz.
  5. If band steering is enabled, disable it to split the networks.
  6. Rename each band separately and save the changes.
  7. Reconnect your devices to the preferred band for better range.

Some apps will only let you toggle each band on or off, without renaming. If that is the case, you may still need to use the web admin panel to fully separate them.

How To Switch Between Bands On Your Device

Even if the router keeps both bands under one name, or you have already split them, your device might need to be nudged to the correct one. There is no universal “change Wifi Hertz” button on most devices, instead you choose which network to connect to.

On Windows Computers

  1. Click the Wi-Fi icon in the system tray.
  2. Look through the list of networks. If split, you will see both names, such as the 2G and 5G versions.
  3. Click the one you want. For better range far away, pick the 2.4 GHz named network.
  4. If it keeps reconnecting to the wrong one, forget both networks and reconnect to your preferred one first.

On Mac Computers

  1. Click the Wi-Fi icon in the menu bar.
  2. Select the specific 2.4 GHz or 5 GHz network if they are split.
  3. Hold the option key while clicking the Wi-Fi icon for more details, which can help identify which band you are currently on.

On Android Devices

  1. Open Settings and go to Wi-Fi.
  2. Tap the network name you want to connect to from the list.
  3. If split, pick the one labeled for the band you need.
  4. Some Android versions allow you to “forget” a network to stop automatic switching.

On iOS And iPadOS

  1. Open Settings and tap Wi-Fi.
  2. Tap the network you wish to use. If they are split, choose the correct one.
  3. To stop a device from hopping, forgetting and reconnecting to the desired band is often the most effective way.

Dealing With Band Steering And Unified SSIDs

Band steering is designed to do the thinking for you. It tries to push capable devices to 5 GHz when close and to 2.4 GHz when weak. In theory this is great, but in practice it can be stubborn. A device might be just far enough that it should be on 2.4 GHz for better range, yet band steering keeps forcing it to a barely connected 5 GHz signal.

The most reliable fix when trying to figure out How to Change Wifi Hertz? is to split the networks. By giving them two different names and passwords, you take full control. Your devices will no longer guess, they will connect to exactly what you choose.

If your router does not allow disabling band steering at all, there are a couple of workarounds. You can move closer to the router while connecting to force the desired band, or temporarily turn off one band entirely, connect your device, then turn the other back on. This is not ideal, but it works for many routers that are locked down.

Changing The Frequency On Mesh Wi-Fi Systems

Mesh systems are incredibly common now and usually hide band controls more aggressively than a single router. Many rely entirely on smart roaming and band steering to cover large homes. This can be frustrating when your only goal is better range in one specific area.

What You Can Typically Do

  • Check the app: Look for advanced Wi-Fi settings. Some mesh apps allow splitting, others do not.
  • Look for “Separate Bands”: A small toggle may exist under wireless settings, even if buried in advanced menus.
  • Use device side choice: If splitting is not possible, connecting by trying the network in the weak spot is often your only option. Devices will naturally fall to 2.4 GHz as 5 GHz becomes unusable.
  • Consider placement: With mesh, moving a node closer to the dead zone is often far more effective than trying to force a band that simply cannot reach.

It is worth noting that some mesh systems intentionally remove this option. If you cannot find it after checking every advanced menu, the system was likely designed with automatic band selection in mind.

When 2.4 GHz Is Better And When 5 GHz Is Better

Knowing when to switch is just as important as knowing How to Change Wifi Hertz?. Picking the wrong band for the situation will undo all of your effort.

Situation Recommended Band Reason
Far away from router (two or more walls) 2.4 GHz Longest range and best at passing through obstacles for better coverage.
Basement, attic, or detached area 2.4 GHz More likely to reach through thick floors, concrete, or extra distance.
In the same room as the router 5 GHz Much faster with less interference, ideal for large files or smooth streaming.
One wall away with open layout 5 GHz (test first) Often still usable and gives better speeds if not too congested.
Mostly smart plugs, sensors, or IoT devices 2.4 GHz Many of these only support 2.4 GHz and it reaches farther throughout the home.
Online gaming very close to router 5 GHz Lower latency potential in an uncongested space.

A good habit is to test both. Connect to 5 GHz near the edge of its range and see if it loads pages reliably. If pages stall or constantly reload, switch to 2.4 GHz. For pure range, 2.4 GHz will almost always win.

Practical Tips For Better Range Without Only Switching Frequencies

While changing the hertz is one of the most direct answers to better range, it is rarely the only fix. Combining a few of these will give far better results than just picking a band alone.

Optimize Router Placement

  • Go central: Place your router as close to the middle of your home as possible. Corners are the worst spots.
  • Go high: Elevate it off the floor. A shelf or table is better than the ground.
  • Keep clear: Avoid placing it behind TVs, inside cabinets, or near large metal objects.
  • Keep away from interference: Try to keep it away from microwaves, thick refrigerators, or large fish tanks where possible.

Tweak Network Usage

  • Update firmware: Check for router firmware updates through the app or admin panel. Updates can improve stability and range over time.
  • Pick better channels: If your area is packed, switching to a less crowded channel on 2.4 GHz can help. Avoid overlapping with neighbors.
  • Limit unnecessary devices: Old devices left connected can sometimes add overhead.

Expand Coverage If Needed

  • Use wired backhaul: If using mesh or extenders, a wired connection between units is far better than wireless repeating.
  • Consider placement over powerline: Powerline extenders can be hit or miss depending on your home’s wiring.
  • Don’t over-repeat: Each wireless hop can cut usable range and speed, so extending only where truly needed is best.

Common Mistakes To Avoid When Trying This

When searching for How to Change Wifi Hertz? many people run into the same avoidable errors. Steering clear of these will keep things simple and safe.

  • Thinking “higher hertz” means better range: The opposite is true. Higher GHz equals shorter range in almost all home environments.
  • Turning off 2.4 GHz entirely: Unless every single device you own supports 5 GHz or 6 GHz, this will knock off smart home devices and any old gadgets.
  • Changing settings blindly: Only change wireless band settings. Avoid touching anything labeled DHCP, WAN, or routing unless you know exactly what it does.
  • Forcing distance with 5 GHz: If it will not connect two rooms away, no amount of router tweaking will make it reach reliably.
  • Resetting out of frustration too soon: Try splitting bands and device choice first. A reset should be your absolute last option.
  • Expecting miracles through concrete: 2.4 GHz helps the most, but multiple concrete floors or thick concrete walls will still be extremely challenging.

Troubleshooting If You Can’t Find The Option To Change Wifi Hertz

Not all routers allow manual band control. If you have gone through the admin panel and the mobile app with no luck, try these steps before giving up.

Update Your Firmware

Some older firmwares hide band steering options. Updating to the latest available firmware through the official app or panel can sometimes expose them.

Switch To Advanced View

Many admin panels have a Basic and Advanced toggle in the top corner. If you are in Basic view, switch to Advanced and recheck the wireless section.

Try A Different Browser

Occasionally, browser extensions or certain browsers can fail to load full menus. Try a clean browser with no extensions enabled.

Check ISP Provided Router Limitations

Some routers provided by internet service providers have locked down their admin panels. You may be able to change the network name and password, but band splitting may be removed entirely. In those cases, your only real option is device side selection or replacing the router with your own.

Use Device Roaming Behavior To Your Advantage

If you cannot split, walk to the edge of weak coverage with your device. As the 5 GHz signal becomes too weak, most modern devices will automatically try to connect to 2.4 GHz if available. This is not instant, but it is often enough for better range in dead spots.

Frequently Asked Questions

Is changing Wifi Hertz the same as changing the channel?

No. Changing the hertz means changing between frequency bands, such as 2.4 GHz and 5 GHz. Changing the channel means picking a different path within that same band. Both can help with congestion, but only changing bands will have the large effect on range.

Will changing to 2.4 GHz make my internet slower?

It can, especially if the band is very crowded or if you are very close to the router. However, if 5 GHz is unusable at your location, 2.4 GHz will feel much faster and more reliable than a constantly dropping signal.

Can I force every device to use 2.4 GHz for better range?

Only if you split the bands and connect them to the 2.4 GHz network. If your router merges them with band steering, you cannot force all devices at once. Some devices will always prefer 5 GHz when it is strong enough.

Why can’t I see the 5 GHz network on some of my devices?

Either the device does not support 5 GHz, the band is disabled on your router, or you are too far away and it is not broadcasting enough for that device to detect. Very old devices are almost always the culprit for this.

Does 6 GHz help with range?

No. 6 GHz has the shortest range out of all of them. For better range, you should avoid 6 GHz and use 2.4 GHz instead.

Will splitting bands hurt my network?

No. Splitting bands simply gives you two separate networks to choose from. Your total internet speed from your provider stays the same. You are just choosing which path your device takes.

How do I know which band I am currently connected to?

On many phones and computers you cannot see the exact GHz number directly. The easiest way is to look at the network name if split. If merged, you can move closer to the router and see which one it prefers, or check connection details on some advanced network menus.

Is this safe to do on any router?

Yes, changing between 2.4 GHz and 5 GHz through your official settings is safe and reversible. Just avoid changing unknown advanced values. If something goes wrong, you can always re-enable band steering or restore defaults.

Conclusion

When it comes down to it, the answer to How to Change Wifi Hertz? is to switch from a higher frequency band to a lower one when range is your goal. For most homes struggling with dead spots, that means moving far away devices over to 2.4 GHz. For devices near the router, 5 GHz will usually be the smarter choice for speed.

The process is straightforward for most dual-band routers. Access your router panel or app, split the bands if they are merged, and connect each device to the band that fits its distance. If your router locks these options, device side selection combined with better router placement will still go a long way.

Remember, frequency is only one piece of the puzzle. Central placement, a clear path, up to date firmware, and smart use of your bands together will always beat relying on one trick alone. With the steps in this guide, you should be able to get far more usable coverage in the areas that have been giving you trouble for far too long.
