Why Does My Acer Laptop Keep Disconnecting From The Internet? | Fix It Fast

Common Symptoms, Likely Causes, Fast Fix

Use this quick map to point you in the right direction.

Quick Wins: Stable Connection In Minutes

Work through these in order. Many issues clear up here.

1. Toggle Airplane mode off/on, then reconnect to your SSID.
2. Forget the network, reconnect, and re-enter the password. Windows explains how on the official Wi-Fi fix page.
3. Power cycle gear: shut the laptop down, unplug modem/router for 60 seconds, start modem, then router, then the laptop.
4. Move closer to the access point. Thick walls and metal chew signal strength.
5. Test 5 GHz if your router offers separate SSIDs. It’s steadier and less crowded than 2.4 GHz.
6. Pause VPNs and security suites for a test session. If stability returns, add Wi-Fi processes to their allow lists.
7. Try a different DNS (e.g., your ISP’s, or public resolvers) to rule out name-resolution blips.

Acer Laptop Keeps Disconnecting From Wi-Fi: Core Fixes

Now lock in settings that prevent common drop triggers.

Update The Wireless Driver The Right Way

Drivers are the backbone of stability. Use Acer’s build first, then Intel’s only if Acer lags far behind.

1. Get your exact model from the bottom label or in System Information.
2. Download the latest Wi-Fi driver from Acer Drivers & Manuals. Install, then reboot.
3. If issues persist and the adapter is Intel (AX200/AX201/AX211 etc.), compare versions with Intel’s notes. Only if Acer’s package is older, install the matching Intel package, then reboot.
4. After any driver change, delete old Wi-Fi profiles: open Settings > Network & Internet > Wi-Fi > Manage known networks and rebuild your main SSID.

Stop Windows From Sleeping The Adapter

Two switches commonly end idle dropouts.

• Device Manager → Network adapters → your Wi-Fi → Power Management: uncheck “Allow the computer to turn off this device to save power”.
• Control Panel > Power Options > Change plan settings > Advanced: set Wireless Adapter Settings > Power Saving Mode to Maximum Performance for both Plugged in and On battery.

Dial In Advanced Adapter Settings

These values work well for most home setups and reduce mid-session roaming and stalls. Vendor names vary a bit; match what you see.

• Preferred Band: 5 GHz.
• Roaming Aggressiveness: Medium (home mesh) or Low (single router) to avoid needless roam attempts. Intel’s guidance lists Medium as the default sweet spot.
• Channel Width: 20 MHz on 2.4 GHz; Auto/40/80 on 5 GHz.
• 802.11n/ac/ax Mode: Enable the newest mode your router supports.
• Transmit Power: Highest.
• U-APSD: Off if you see call drops; some APs handle it poorly.

Intel documents these options and recommended values in its 802.11ax settings guide.

Make Routers Less Fussy

Small tweaks on the access point can stop flip-flopping between bands and reduce retries.

• Give 2.4 GHz and 5 GHz their own SSIDs so you can choose the steadier band.
• Pick a clean channel (1/6/11 on 2.4 GHz). On 5 GHz, Auto usually picks well.
• Security: WPA2-AES or WPA3. Avoid mixed WEP/WPA, which causes reauth glitches.
• Turn off “Smart Connect”/aggressive band steering if it keeps pushing you to 2.4 GHz mid-call.
• Extend the DHCP lease time to reduce periodic renew drops.
• Update router firmware.

Why Your Acer Drops Internet During Calls Or Streams

Live traffic exposes weak links. Here’s how to keep it steady.

• Stick to 5 GHz. You’ll dodge Bluetooth and microwave noise common on 2.4 GHz.
• Keep a clear line of sight. Even one reinforced wall can tank throughput.
• Move USB 3 hubs and dongles. They spew noise near 2.4 GHz; distance helps.
• Pause cloud backup and large downloads while on a meeting.
• Try Ethernet for mission-critical sessions; a compact USB-C adapter works well.

Advanced Windows Fixes (Use With Care)

When The Basics Don’t Hold

Reset Network Stack

Run cmd as admin now:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns
shutdown /r /t 0

Rebuild The Adapter

1. Device Manager → Network adapters → your Wi-Fi → Uninstall device (check “Delete the driver” if shown).
2. Reboot and install the fresh package from Acer, then set power and advanced options again.

Check Windows Features That Nudge Wi-Fi

• Turn off Fast Startup to avoid half-awake drivers after hibernate.
• In Wi-Fi > Hardware properties, try Use device MAC instead of Randomized if captive portals or MAC filtering are used.
• Update Windows and BIOS from Acer’s support page for your exact model.

Router And Mesh Tweaks That Stop Dropouts

If several rooms need coverage, tune the mesh so clients don’t bounce around.

• Set a gentle roam threshold; avoid strict RSSI kicks that push clients mid-call.
• Place nodes with one or two walls between them, not at the edge of signal.
• Backhaul with Ethernet if possible. Wireless backhaul competes with client traffic.

Troubleshoot DNS, IP, And Authentication

When Wi-Fi shows “Connected” but pages hang, look here.

• DNS: Test your ISP DNS, or a public resolver. If names resolve slowly, switch to a known-good resolver and test for a day.
• DHCP: If the IP keeps changing mid-session, extend the lease on the router, or set a reserved IP for the laptop’s MAC.
• Authentication: Use WPA2-AES or WPA3 only. Older mixed modes cause timeouts.

When Only One Room Misbehaves

That room might be a “radio pit.”

• Change the router’s position by even half a meter.
• Switch to a different 5 GHz channel group (36–48 vs 149–161).
• Try a wired backhaul or a single extra access point in that area.

Another Close Look: Acer Laptop Disconnects From The Internet After Sleep

Wake-from-sleep hiccups often come from power and Fast Startup interactions.

• Disable Fast Startup in Power Options.
• In Device Manager, clear the “Allow the computer to turn off this device” box again after major updates—it can revert.
• Rebuild the driver if wake fails once per day; corruption in the profile store can cause it.

When To Suspect Hardware

Hardware faults are rare, yet they do happen.

• The same SSID is rock solid on phones and other laptops in the same spot.
• A USB Wi-Fi dongle is stable while the internal card drops.
• Wiggles or lid movement cause instant disconnects (loose antenna leads).

If the signs match, contact Acer support for repair options and approved parts through your region’s support channel.

Keep It Solid Day After Day

A few habits go a long way.

• Update Windows, drivers, and router firmware on a steady schedule.
• Reboot the router after major ISP work or power events.
• Use separate SSIDs for 2.4 GHz and 5 GHz so you can pick the right band.
• Back up your driver installers in a safe folder for quick recovery now.
• Document the adapter settings that work on your Acer so you can restore them after updates.
