Some new iPhone 18 Pro and 18 Pro Max owners have noticed Wi-Fi problems right out of the box. Connections drop during setup, speeds are much slower than older iPhones, or Wi-Fi toggles off and on after unlocking the phone.
Many iPhone 18 Pro owners say their Wi-Fi connection drops repeatedly, even when full signal bars are shown. Some experienced failures or slowdowns during the initial setup because Wi-Fi disconnected mid-process, while others noticed that simply unlocking the phone causes Wi-Fi to briefly shut off and reconnect. In several cases, speeds on the iPhone 18 Pro were far lower than on older iPhones connected to the same network, and this instability also led to missed FaceTime calls and failures with Wi-Fi Calling.
1. Apple Watch on wrist + unlocked
Some users report that when the iPhone shows the Lock Screen or unlocks, Wi-Fi briefly shuts off and back on, sometimes dropping Bluetooth (AirPods, CarPlay).
Take the Watch off your wrist, keep it locked, or power it off.
On the Watch:
Press the side button to open Control Center, then tap the Wi-Fi button. Apple Watch temporarily disconnects from the Wi-Fi network. When you leave and later return to the place where you were connected to Wi-Fi, Apple Watch automatically joins that network again unless you’ve forgotten it on your iPhone.
You may also need to turn off Unlock with Apple Watch. On iPhone, go to Settings > Face ID & Passcode, enter your passcode, scroll down, then turn off Apple Watch (below Unlock with Apple Watch).
2. VPN profiles left behind
VPN and other third-party security software can potentially block some connections, such as those required to access the internet. Tap Settings > General > VPN & Device Management and check the profiles there. If the setting isn’t managed and required by your organization, you can turn it off, change it, or delete it. Delete VPN apps you don’t use, reboot, and test again. Press and hold either volume button and the side button until the power-off slider appears. Drag the slider, then wait 30 seconds for your device to turn off. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.
3. Older HomePods or Apple TV
Some report AirPlay or Wi-Fi instability linked to outdated firmware.
On HomePod:
Open the Home app. Tap or click the More button, then tap Home Settings. Tap Software Update. If there’s a new update, select Update.
On Apple TV:
Go to Settings and choose System. Tap Software Updates, then select Update Software. If there’s an update, select Download and Install.
4. Router / mesh quirks
Some users report that band steering or 6 GHz (Wi-Fi 6E) networks cause drops on the iPhone 18 Pro. Make sure that all routers on your network use the same name for every band they support. If you give your 2.4 GHz, 5 GHz, or 6 GHz bands different names, devices might not connect reliably to your network, to all routers on your network, or to all available bands of your routers.
Restart your router and cable modem by unplugging the devices and then plugging them back in.
Try disabling Private Wi-Fi Address in Wi-Fi settings. If your device can’t join a Wi-Fi network, can’t access network resources or the internet after joining, or can’t use certain software with private addresses, you should install the latest software updates. Then try again before you decide whether to turn this feature off. Go to Settings. Tap General. Tap Software Update.
Open the Settings app, then tap Wi-Fi. If you aren’t currently connected to the network, tap Edit in the upper-right corner of the screen. Tap the More Info button next to the network name. Tap Private Wi-Fi Address, then tap Off, Fixed, or Rotating.
5. Network settings clutter
Old Wi-Fi or VPN configs interfering. You can try to fix this by forgetting and rejoining Wi-Fi; if that fails, Reset Network Settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings). Note that doing so resets all Wi-Fi networks and passwords, cellular settings, and VPN and APN settings, but keeps your data and apps.
To forget a network:
Open Settings, then tap Wi-Fi. Tap Edit in the corner of the screen to view the networks known to your device. Tap the More Info button next to the network name. To forget the network and its password, tap Forget This Network, then tap Forget to confirm.
6. Persistent system conflict
If the above don’t work, try Reset All Settings by going to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. All settings—including network settings, the keyboard dictionary, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
Some users report that the same Wi-Fi drop can knock wireless CarPlay offline.
