WiFi Not Working on One UI 8: How to Fix

Samsung seems to have made quite a few improvements in its latest OS release, especially when compared to its predecessor, One UI 7. And it has been a fairly successful journey, albeit for a few roadblocks. One such roadblock is the issue with its internet connectivity. Right after users installed the latest One UI 8 on their Galaxy devices, many of them have voiced their concern that the WiFi is no longer working.

Since all the other parameters remained constant and the OS is the only thing that has undergone a change, it’s fair to assume that the culprit is the latest OS build only. With that said, we did come across a few nifty workarounds that should help you rectify this problem. And in this guide, we will make you aware of just that. So without further ado, let’s get started.

It is recommended that you try each of the below-listed workarounds and then see which one works out in your favor. So on that note, let’s get started.

FIX 1: Toggle Airplane Mode

First off, you should consider enabling and then disabling the airplane mode. Doing so will refresh the underlying network settings and could well rectify the underlying WiFi issue that we are currently dealing with. So try out this network tweak using the below-listed steps and then check out the results:

  1. Bring up the Quick Settings panel from the top of the screen.
  2. Then tap on Airplane Mode to enable it.
  3. Wait for a few seconds and then disable it.
  4. Check if it fixes the WiFi not working issue on One UI 8.

FIX 2: Enable WiFi Safe Mode

  1. First off, delete the saved WiFi 6 network to which you are trying to connect.
  2. Then tap on Build Number 7 times to enable Developer Options.
  3. Now go to Developer Options and enable WiFi Safe Mode.
  4. Then s elect your Wi-Fi network, set a static IP address, and select Use Phone’s MAC.
  5. Finally, restart your device and check out the result.

FIX 3: Turn off Intelligent WiFi

For some, the Intelligent WiFi feature turned out to be the culprit and upon disabling it, the issue was rectified. So give it a try using the below-given instructions and check if it spells out success for you or not.

  1. Go to Settings > Connections > WiFi > tap on the overflow icon at the top right.
  2. Then choose Advanced and you will be taken to the Intelligent WiFi page.
  3. From there, simply disable the toggle next to Turn on WiFi automatically.
  4. Now check if it fixes the WiFi not working issue on One UI 8.

FIX 4: Install Pending Updates

In some instances, the issue might be due to a buggy update rolled out by the OEM.

So make sure to download and install the pending updates on your device, and then check if it fixes the WiFi not working issue on One UI 8.

FIX 5: Switch to Private DNS

Some users were able to rectify this issue after switching over to a private Domain Name Server instead of the one provided by their ISP. So you could opt for Google, Cloudflare, or AdGuard’s DNS using the instructions given below and then check if your Galaxy S24 Ultra is able to connect to WiFi 6 5GHz.

  1. Head over to Settings > Connections > More Connection Settings.
  2. Then go to Private DNS and select Private DNS provider hostname.
  3. Now type in any of the three below listed DNS addresses and hit Save. Google DNS: dns.google Cloudflare DNS: 1dot1dot1dot1.cloudflare-dns.com AdGuard: dns.adguard.com
  4. Now check if your device is able to connect to a WiFi network.

FIX 6: Switch from DHCP to STATIC

As is evident from their names, the static IP address is the one that is permanently assigned to your device and it remains the same even after you reboot your device. On the other hand, DHCP dynamically assigns IP addresses to all the devices connected to a network, and this IP address keeps on changing. As of now, some users have reported that they were able to achieve success after switching from a dynamic to a static IP address. So let’s put this fix to the test and check out the results:

  1. To begin with, head over to Settings > Connections > WiFi.
  2. After that, tap on the Settings icon next to your WiFi.
  3. Then tap on Advanced/view more, select Static under IP settings, and hit Save.
  4. Check if it fixes the WiFi not working issue on your device running One UI 8.

FIX 7: Disable Fast Transition

Most of today’s smartphones support the 802.11r WiFi standard, which is activated via the Fast Transition feature. On paper, the latest flagships from Samsung should support it as well, but that doesn’t seem to be the case. This is because some of the users were able to resolve the WiFi issues after disabling the Fast Transition and opting for the traditional and legacy WiFi standard. So let’s execute this fix and test out the results in our case as well:

  1. Login to your Router’s settings page via any of the two IP Addresses: 192.168.0.1 192.168.1.1
  2. Then go to the Internet > Security tab.
  3. Select Disable next to Fast Transition and then save the changes.
  4. Check if it fixes the WiFi not working issue on One UI 8.

FIX 8: Reset Mobile Network Settings

  1. Go to Settings, and tap on General management.
  2. Then tap Reset > Reset mobile network settings.
  3. Finally, tap Reset settings > Reset to confirm.
  4. Check whether it fixes the underlying WiFi bug.

FIX 9: Reset WiFi

If none of the aforementioned spelled out success for you, then your last course of action should be to reset the network settings on your device. Doing so will revert all the network settings to their default state. Moreover, it will also remove all the paired Bluetooth devices and the saved WiFi passwords. so make sure to sync those passwords with your account before proceeding with the below steps.

  1. To begin with, go to Settings > General management.
  2. Then tap Reset > Reset Wi-Fi and Bluetooth settings.
  3. Now tap Reset settings. Then reconnect to your WiFi.

FIX 10: Reset Device

Even resetting the network didn’t get the job done? Well, then you’re left with no choice but to opt for the nuclear route of factory resetting your device. But before that, make sure to take a complete device backup. Once done’s let’s get going:

  1. Head over to Settings > General Management.
  2. Then tap on Reset > Factory data reset > Reset.
  3. Tap Delete all > Enter your Samsung account credentials.
  4. Then, set up the device from scratch and check the result.
