Cannot Connect To 2.4 GHz Network: what do I do? – Robot Powered Home

I configured my network to automatically connect my smart devices at home and devices far away to the 2.4ghz band of my dual-band router.

devices that are closer and generally use more data like my game console, tv, and computer, connect at 5ghz.

The same goes for my phone and laptop, which automatically switch between the 2.4ghz and 5ghz bands based on distance from the router as I move around the house.

but lately my connection to the 2.4ghz band has been pretty spotty and most of the time my devices won’t even connect to the wi-fi network.

Without the convenience of Wi-Fi, work would be difficult to complete on time, so I went online to find out why this was happening.

I was hoping to find something that would fix this once and for all and get my router back to seamlessly switching between 2.4 and 5ghz wi-fi.

after a few hours of research that included reading forum posts and router documentation, I was ready with a few fixes that I knew might work.

I tried them on my router and devices and got it working in just a few minutes.

This article compiles everything I found and should help you get back on the 2.4ghz network.

If your device cannot connect to your 2.4ghz wifi band, please check your device settings and make sure it is set to connect to the 2.4ghz band. you can also update your router and device and reboot or reset the router.

Learn later in this article how you can update your router’s firmware and why it’s important to keep your device up to date with the latest software.

check device settings

Some devices have a setting that, when turned on, won’t connect to 2.4 GHz Wi-Fi networks.

The feature may be intended to maximize the device’s performance on Wi-Fi using only 5GHz, but it doesn’t allow you to connect to the slower 2.4GHz band.

check your device settings to see if your device has the same or similar settings, and turn it off for now.

try to connect the device to the 2.4ghz access point now and see if you can complete the connection.

update your device

As the software for your device is being worked on, the developers will release updates and patches for it from time to time.

These patches fix bugs and other issues that might have affected device performance.

bugs cause devices not to connect to wi-fi networks and may have prevented your device from connecting specifically to the 2.4ghz band.

This is why it is very important to keep your devices up to date with the latest version of patches and bug fixes.

check for updates to your devices and install them as soon as possible.

After updating your device, please try connecting the device to the 2.4ghz band again.

update router firmware

The same logic applies to your router, but getting it updated is a bit different from updating your other devices.

Routers generally update their firmware instead of software because routers use software that interacts better with their hardware.

To update your router’s firmware:

  1. Go to your router’s support website.
  2. Check for firmware updates for your router model and download it to your computer.
  3. Open a new tab browser.
  4. type 192.168.1.1 in the address bar and press enter.
  5. login to your router. you can find the default login details on a label under the router.
  6. go to the administration section. if it’s not present, you can refer to your router’s manual for the exact section to go to.
  7. upload the file you just downloaded to your router.
  8. start the firmware update.
  9. the router will reboot after the firmware update is complete.

try connecting your devices to the 2.4ghz access point again to see if the update worked.

reboot your router

If a router firmware update didn’t work, and neither did a device update, you can try restarting your router to see if that helps.

reboots act like a soft reset and have been seen to fix quite a few bugs with many routers.

The best way to do this would be to power cycle, so follow the steps below to do so:

  1. turn off the router.
  2. unplug it from the wall.
  3. plug it back in only after waiting at least a minute.
  4. turn on the router.

After the router powers on, connect the device to the 2.4ghz access point.

You can try this a few more times if it doesn’t work the first time.

reset your router

If a restart doesn’t work, the next logical step to take is to factory reset the router.

this will erase all settings including your custom wi-fi name, quality of service settings and restore wi-fi password to default.

only do this if you’re ready to set everything up from scratch.

to reboot your router:

  1. look for the button labeled “reset” on the back of the router. it should be recessed and look like a pinhole.
  2. take a paper clip or something non-metallic and pointed to press the button.
  3. hold the button down for at least 30 seconds with the tool .
  4. the router will reboot and when it comes back on, the process is complete.

try connecting a device to the router’s 2.4ghz band after setting it up to see if the reboot worked.

contact support

If none of these troubleshooting steps works out for you, please contact your router’s technical support.

for routers you have leased from your isp, it is best to contact your isp.

They’ll walk you through additional steps and may ask you to send them to them if they can’t fix it over the phone.

final thoughts

2.4ghz is used almost exclusively for the range advantage it has over 5ghz, and due to cost, most smart home devices also only use 2.4ghz wifi.

If your dual-band router has reliability issues with 2.4ghz, consider getting a 2.4ghz single-band router and use the dual-band router for 5ghz wi-fi.

I would recommend the asus n300 single band router if you want a good 2.4ghz router.

Interference won’t be a big problem if you place your router strategically.
