ASUS's Wi-Fi article for notebooks, desktops, all-in-ones, gaming handhelds and mini PCs starts by finding whether the fault is your machine or your network, with a phone as a comparison: if both your machine and a smartphone cannot get online, the problem is usually the internet facilities or provider; if the machine cannot but the phone can, work through the article's solutions. Those include improving performance with the right power mode (a low-power mode can slow the network), using System Diagnosis in MyASUS to check wireless connectivity, fixing a wireless adapter with a yellow exclamation in Device Manager (laptops only), updating the wireless and Bluetooth drivers through Device Manager and MyASUS, and restoring BIOS defaults with F2.
The ROG Ally X sits on your lap or a couch far from the router, so signal is a real factor.
Differential
Likely causes of “ASUS laptops will not connect to Wi-Fi or keeps disconnecting”, and how to tell them apart
- 1
The network or provider
What separates it Your phone cannot get online either because of the network or provider
How to confirm ASUS says if both the device and a smartphone cannot connect, the problem usually lies with the internet facilities or provider
- 2
A power mode that limits the network
What separates it Wi-Fi is slow on battery or in a quiet mode
How to confirm ASUS says improving system performance can help network speed; raise the power mode
- 3
A driver problem
What separates it The Wi-Fi adapter has a yellow exclamation in Device Manager
How to confirm ASUS says to update the wireless drivers through Device Manager and MyASUS
- 4
BIOS settings changed
What separates it Wi-Fi vanished after a BIOS change because the BIOS settings were changed
How to confirm Restore BIOS defaults with F2, and check the Wi-Fi again
- 5
A hardware fault
What separates it MyASUS System Diagnosis reports a wireless problem because of a hardware fault
How to confirm Follow MyASUS's suggestions and contact an ASUS service center if it fails
Before you touch a setting
Record this first — changing settings destroys the evidence
- Which ASUS machine you have and its BIOS and wireless driver versions
- Whether a smartphone gets online on the same network
- What MyASUS System Diagnosis and Device Manager report
- Whether the fault is on battery only or with a certain power mode

Model-specific
What is true of this model and not of its siblings
- Wireless by model
- Zenbook S14, Vivobook S15, ProArt P16, Zephyrus G14 and ROG Ally X all use built-in wireless modules updated through MyASUS. The Snapdragon Vivobook uses Arm-specific drivers.
- Handheld placement
- The Ally X is used away from the router, so test near the router to separate signal from a fault.
- Tools and supplies
- Your router's admin page or app, your Wi-Fi password, a smartphone for comparison and a dry towel for the desk. The machine should not be opened at home.
- Repair cost
- A Wi-Fi fault is almost always the router, a driver or a setting, which costs nothing. If the wireless card is at fault, an independent shop repair is typically $99 to $299 with a free diagnostic, per BadgerLayer's 2026 laptop repair guide.
- Other models this page answers
- These steps also fit the ProArt P16 H7606, ROG Zephyrus G14 GA403, Vivobook S 15 S5507.
Stop boundary
When this stops being a self-service repair
- !If MyASUS reports a wireless hardware fault, contact an ASUS service center
- !If Wi-Fi fails on every network after driver and BIOS steps, book a service check
- !If only one network fails, contact its owner or your ISP

Exact questions
Common questions
How do I forget and rejoin a network on Windows?+
Open Settings, Network & internet, Wi-Fi, Manage known networks, select the network and choose Forget. Then join it again and re-enter the password, which clears a stale saved profile.
Does the router band matter for an ASUS laptop?+
Yes. Try the 5 GHz name if the laptop sees both bands, since it is usually faster at short range, and fall back to 2.4 GHz through walls, where it reaches further but is slower and more crowded.
How can I tell the laptop from the router?+
Test a phone on the same network. If the phone also loses the connection, the router or provider is at fault. If only the laptop fails, the fault is in its driver, settings or wireless card.
How does ASUS separate device from network?+
It says to compare your device with a smartphone on the same network: if neither can connect, the problem is the internet facilities or provider; if only the device fails, use its solutions.
What is MyASUS System Diagnosis?+
A tool in the MyASUS app that checks the machine, including wireless connectivity; ASUS says some machines show only partial features.
Does power mode affect Wi-Fi?+
ASUS says improving system performance will help with network speed problems; raise the power mode and connect the charger.
Which Wi-Fi do the machines have?+
ASUS's article does not list per model; check Device Manager for the adapter and update its driver. Newer Zenbook and ROG models use current Wi-Fi standards.
Is Wi-Fi shared with Bluetooth?+
Usually on one wireless card. A fault in both points at the card or its driver.
What if the adapter is missing?+
ASUS says a laptop with a yellow exclamation in Device Manager should follow its recovery steps; if it is missing entirely, restore BIOS defaults and contact ASUS.
Do I need a part number for a Wi-Fi card?+
No. ASUS identifies the machine by model and serial number.
