You're trying to get your ASUS ROG Phone 9 online for a game or just to browse, and it's stuck on "Connecting..." or "Saved." It's a frustrating roadblock, especially on a phone built for peak performance. The good news is that Wi-Fi issues on Android 15 are almost always a software hiccup you can fix yourself.
Toggle Wi-Fi and Restart Your Phone
Start with the simplest fix. Swipe down from the top of your screen to open the Quick Settings panel and tap the Wi-Fi icon to turn it off. Wait five seconds, then tap it again to turn it back on. This forces your phone to drop the connection and re-scan for networks, which often clears up a temporary glitch.
If that doesn't work, give your ROG Phone 9 a full restart. Press and hold the power button until the power menu appears, then tap "Restart." A reboot clears out any minor software bugs that might be interfering with the Wi-Fi radio.
Forget the Network and Reconnect
Your phone might be holding onto outdated or corrupted login info for your network. To clear it, go to Settings > Network & internet > Internet. Tap the gear icon next to your Wi-Fi network's name and select Forget.
Now, go back to the list of available networks, tap on yours, and enter the password again. This is the most effective fix if you've recently changed your Wi-Fi password or gotten a new router.
Use Airplane Mode to Reset Radios
This trick resets all your phone's wireless connections at once. Swipe down for Quick Settings and tap the Airplane Mode icon. Leave it enabled for about 15 seconds, then turn it off. Your phone will re-establish connections to cellular, Wi-Fi, and Bluetooth, which can knock loose a stubborn Wi-Fi issue.
Check for Router Issues
Before you spend more time on your phone, make sure the problem isn't with your internet source. Unplug your router and modem from power, wait a full 60 seconds, and plug them back in. This simple reboot fixes a huge number of home network problems.
Also, see if other devices in your home can connect to Wi-Fi. If they can't, the issue is definitely with your router or internet service, not your ROG Phone 9.
Disable Smart Network Switching
Android has a feature designed to save data by switching to mobile data when Wi-Fi is weak. On the ROG Phone 9, this can sometimes be too aggressive and prevent a connection. Go to Settings > Network & internet > Internet.
Tap the gear icon, then go to Network preferences. Look for an option called "Switch to mobile data automatically" or "Adaptive connectivity" and turn it off. This tells your phone to stay on Wi-Fi.
Review Your Power and Game Settings
The ROG Phone 9 has powerful modes that can affect connectivity. First, check if any battery-saving mode is active. Go to Settings > Battery and make sure Power Master or any battery saver is turned off, as these can limit background network activity.
Also, take a look in the Armoury Crate app. If you have a particularly aggressive X Sense game profile active, it might prioritize performance in a way that could interfere. Try switching to a balanced profile like "Dynamic" to see if it helps.
Update Your Software
Outdated software is a common cause of bugs, including Wi-Fi problems. ASUS regularly releases updates that fix these kinds of issues. Go to Settings > System > System update and tap "Check for update."
Install any available updates. I've seen updates specifically target network stability and modem performance, so this is a crucial step.
Reset Your Network Settings
This is a more thorough step that resets all network-related configurations back to factory defaults. It will erase all saved Wi-Fi networks, Bluetooth pairings, and mobile network settings. Go to Settings > System > Reset options.
Tap Reset Wi-Fi, mobile & Bluetooth and confirm. After your phone reboots, you'll need to reconnect to your Wi-Fi and re-pair any Bluetooth devices, but it often solves persistent connection woes.
Boot Into Safe Mode
A third-party app you installed could be causing the conflict. Common culprits are VPNs, ad blockers, or certain "cleaner" apps. To test this, you need to boot into Safe Mode, which temporarily disables all downloaded apps.
Press and hold the power button until the power menu appears. Then, tap and hold the "Power off" option on your screen. You should see a prompt to reboot to Safe Mode. Tap "OK." If your Wi-Fi works perfectly in Safe Mode, you know an app is to blame. Start by uninstalling recent apps or any related to networking.
Check Date, Time, and Certificate Settings
Incorrect date and time settings can break the security certificates used by Wi-Fi networks. Go to Settings > System > Date & time and ensure "Use network-provided time" is enabled.
For some secure networks (like at a workplace or school), you might also need to install a certificate. If you're trying to connect to such a network, check with the network administrator to ensure you have the correct security profile installed on your phone.
