How to fix OnePlus 6 wifi not connecting issue

Wifi troubles are some of the annoying problems an Android user can experience. In this short troubleshooting guide, we’ll show you the steps to try if your OnePlus 6 wifi is not connecting or encounters a problem.

How to fix OnePlus 6 wifi not connecting issue

Fixing wifi problems is often easy and simple. But just like most Android problems, there’s no direct way to usually identify the cause. There a number of factors to consider for even the most common wifi trouble. Here are the things that you can try to troubleshoot your wifi issue.

Forced reboot

This is the first troubleshooting step that you want to do. Many temporary bugs are fixed and network issues are fixed by refreshing the system. To check if wif functionality is affected by a minor bug, try to simulate the effects of a “battery pull.” On older devices with removable battery packs, an issue like this can be fixed easily by removing the battery. This is not possible for a OnePlus 6 though so you can only try simulate the effects of physically disconnecting the battery. Before you perform a forced reboot, be sure to leave the phone charging for at least 30 minutes. Afterwards, follow the steps below on how to force reboot the device:

  1. Press and hold down the Power button on the right side of the phone
  2. Hold the Power button down for 10-12 seconds, or until the phone vibrates and restarts
  3. If the phone turns off let go then press power again for 1-2 seconds to restart the phone

If your OnePlus 6 is still unresponsive after doing the steps above, continue holding down the power button for another 10 more seconds. Hopefully, this will force it to reboot. If not, proceed to the next troubleshooting step.

Reconnect wifi

Once you’ve restarted the device as detailed above, the next step would be to disconnect from your wifi network, wait a few seconds, then reconnect. This is sometimes helpful in cases wherein wifi functionality suffers temporary glitch while trying to authenticate or re-establish a connection. By manually disconnecting from the network and reconnecting, you are also refreshing the wifi network credentials. If there’s a bug in this part of connection process, this might help.

Check wifi speed

Many Android users mistake slow-wifi-connection issue with No Wifi issue. Sometimes, wifi connection can become too slow that it may cause apps to crash or to appear as if there’s no wifi connection at all. To check if you’re having slow connection issue instead of total non-wifi functionality, follow our suggestions below.

  1. Connect to your home wifi. Make sure you’re not connected to mobile data.
  2. Install a speed test app or open a web browser such as Google Chrome.
  3. Run a speedtest three times and take note of the results. If you’re using a web browser, visit sites like or to run tests.
  4. If you’re getting slow internet speed test results (below 5Mbps), this may be the reason for poor app performance.

If you think your wifi speed test results are below expected speed, you should troubleshoot your wifi connection. If you have a lot of devices that are using your wifi, it’s possible that one or more may be hogging the bandwidth. What you can do in this case is to simply take one or more off the network to free up bandwidth.

Check if other devices can connect

One other way to know if the problem lies on your wifi network (or equipment), you can check if other devices can connect to the internet when on the same wifi network. If you’ve already figured this out ahead of time, just ignore this suggestion.

Reset network settings

This is a staple troubleshooting step for any network-related problem. By doing this, you are basically changing all network settings of your device to their defaults. If a bug is caused by a bad software configuration, this might help. Below are the steps to reset network settings of your OnePlus 6:

  1. Open Settings app.
  2. Tap Backup and reset.
  3. Tap Reset network settings.
  4. Tap Reset settings.

Network powercycle

Restarting your networking equipment is another important troubleshooting step in this case. If you have an older setup with a modem and router, make sure to unplug both of them from the wall outlet for at least 30 seconds. Afterwards, turn on the modem first and wait for it to initialize. Once all the lights are stable, turn the router on.

For those with modem/router setup, all you have to do is to simply unplug the device from the wall outlet for 30 seconds. Then, turn it back on afterwards. If you have multiple devices connected to the router, make sure to powercycle them as well.

Clear cache partition

By clearing the cache partition, we assume that the cause may be related to the system cache. Sometimes, updates may corrupt the system cache, which, in turn, can lead to bugs or slow performance. If you haven’t tried wiping the cache partition since you got the device, try the steps below. This troubleshooting won’t delete personal data or apps so you don’t have to worry about losing anything important. What gets deleted in the process are temporary files that Android users to load apps faster. This cache will be rebuilt over time.

  1. Turn your phone off by pressing down the power key for five seconds. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the volume key and the power button simultaneously until the device vibrates and opens the Recovery menu.
  3. Choose your preferred language.
  4. Using the volume keys to navigate, go to Wipe > Wipe cache > Yes to start the process
  5. Reboot the device after this is done.

Install updates

Some network issues are only fixable by making coding changes with the phone’s modem firmware. Make sure that you device is running the latest available software update to minimize the chance of this problem from happening.

Safe mode

To check if the problem is due to a bad third party app, you want to restart the device to safe mode. Here’s how to boot to safe mode:

  1. Long Press power off button in your phone
  2. You will see the Reboot to safe mode message appear on the screen
  3. Tap OK to enter OnePlus 6 into safe mode
  4. Wait for your phone to restart, after that you can see safe mode symbol at bottom left corner side of the screen
  5. Check how wifi works. Do a speed test if needed.

While running on safe mode, your OnePlus 6 will prevent downloaded apps from running. If wifi works normally on safe mode, that means that one of your apps is to blame. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your OnePlus 6 is still problematic, repeat steps 1-4.

Return software settings to defaults

If you are lucky and the cause of the problem is due to an unknown software bug, factory reset may help. Follow the steps below to refresh the system and set it up as a new device.

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Reboot to recovery mode by pressing and holding (at the same time) the Volume Down and the Power buttons.
  3. When you see the OnePlus icon displayed on your phone, release all keys.
  4. Enter your PIN code if it’s asked.
  5. In recovery, use Volume Up and Down rocker keys in order to scroll within options and use the Power button to select your option.
  6. Select ‘wipe data factory reset’ and wait while the wipe is performed.
  7. Return to main menu of recovery when done and choose ‘reboot system now’.


We don’t think minor wifi problems is caused by hardware malfunction but if all the solutions above won’t help in fixing your problem, we suggest that you contact the phone manufacturer. There’s no perfect electronics and there’s a chance that the reason may be deeper. At this point, it may no longer be fixable on your level so repair may be necessary to address it.
