ASUS A551LN Drivers for Windows 8.1 64-bit – Download
The ASUS A551LN is a 15.6-inch notebook from ASUS's A-series lineup, built around a 4th-generation Intel Core processor and switchable Intel/NVIDIA graphics (Optimus). It originally shipped with Windows 8.1, which is why the OS still asks for driver packages built for that specific release rather than the generic drivers Windows Update installs automatically. This guide collects the official ASUS-signed driver packages for the A551LN under Windows 8.1 64-bit, in the order you should install them, plus fixes for the problems people actually run into (no Wi-Fi after a reinstall, wrong screen resolution, missing touchpad gestures).
ASUS A551LN Driver Downloads (Windows 8.1, 64-bit)
Every link below points to a package hosted on ASUS's own download CDN — not a third-party mirror. If a link ever returns an error, it's almost always because ASUS rotated the file path; in that case use the "Official ASUS A551LN Support" link further down and search the same driver category there.

Recommended Install Order
Installing drivers in the wrong order is the most common reason people end up with a device stuck in Device Manager. On a fresh Windows 8.1 64-bit install, go in this sequence and restart once at the end rather than after every single package:
- Chipset (via Windows Update if ASUS doesn't list one separately for this model)
- Graphics — Intel first, then NVIDIA
- Audio
- LAN (wired)
- Wireless LAN / Wi-Fi
- Bluetooth
- Touchpad (ASUS Smart Gesture)
- ATK / hotkey utilities
- Card reader and any remaining device-specific drivers
Once everything is installed, restart, then open Device Manager and scan for any device still showing a yellow warning triangle.
ASUS A551LN Wi-Fi Not Working After Reinstall
This is the single most common support request for this model. Windows 8.1's built-in driver set often can't identify the A551LN's wireless card at all, so it simply won't appear in the network list.
- Open Device Manager → Network adapters.
- If you see an unrecognized device (sometimes listed under "Other devices"), right-click it and check Properties → Details → Hardware Ids.
- Match that ID against the wireless chipset listed for your unit — this model shipped with either a Ralink, Qualcomm Atheros, or Intel wireless card depending on configuration, so install the matching package from the table above.
- If the laptop has no working network connection at all, download the driver on another PC and transfer it over with a USB flash drive.
Fixing Incorrect Screen Resolution
Right after a clean install, Windows typically falls back to a generic display adapter, which caps you at a low, stretched resolution. If Device Manager shows Microsoft Basic Display Adapter under Display adapters, that's the symptom — install the Intel Graphics driver from the table above, restart, and Windows should switch to the panel's native resolution. Only install the NVIDIA package afterward if you specifically need the discrete GPU for gaming or GPU-accelerated apps.
Touchpad Gestures Not Working
Windows' generic HID driver lets the touchpad move the cursor, but multi-finger gestures (two-finger scroll, pinch-to-zoom, edge swipes) require ASUS's own Smart Gesture package, listed above. Install it, restart, and check Settings → Devices → Touchpad for the extra gesture options.
Frequently Asked Questions
- Is the ASUS A551LN officially supported on Windows 8.1 64-bit?
- Yes — Windows 8.1 64-bit is listed on ASUS's own support page for this model, alongside Windows 8 64-bit and Windows 10 64-bit.
- Can I install a 32-bit driver instead?
- No. Confirm your system type first — installing a 32-bit package on 64-bit Windows will fail or cause instability. Check under System → System type before downloading anything.
- My Wi-Fi driver installs but Wi-Fi still doesn't turn on — why?
- Check for a hardware wireless switch or an Fn+F-key combo for Airplane Mode, and also install the ASUS Wireless Radio Control package above — on some A551LN units this is required alongside the wireless driver itself before the radio will switch on.
- Can I use these drivers on a different ASUS laptop?
- Not safely. Even ASUS models that look similar can use different chipsets, so always match the exact model number before installing.
Why These Drivers, and Not a Third-Party Driver Tool?
Every package linked on this page comes straight from ASUS's own distribution servers rather than a repackaged installer from a generic "driver updater" tool. Automated driver tools frequently misidentify laptop hardware revisions and install the wrong chipset variant, which is a common cause of the exact Device Manager errors this page helps fix. When in doubt, ASUS's own support page for the A551LN is the authoritative source — this guide exists to save you the trouble of hunting through it category by category.
