You are in the middle of a video call or a download when the Wi-Fi icon suddenly shows a globe with a slash — connected, no internet, or dropped entirely. A few seconds later it reconnects on its own, only to drop again twenty minutes later. On a Copilot+ PC that promises all-day productivity, a flaky wireless connection is more than annoying; it breaks the whole pitch.

This problem is especially common on the newest Copilot+ laptops. Snapdragon X machines run ARM64 Wi-Fi drivers written for a brand-new platform, while Intel Core Ultra Series 2 and AMD Ryzen AI 300 models ship with first-generation Wi-Fi 7 or updated Wi-Fi 6E drivers. Early Snapdragon X Elite NPU driver issues taught owners that first-wave drivers need time to mature, and the wireless stack is no different. Disconnects also love to team up with power states — if your laptop misbehaves after waking up, see our guide on Copilot+ PC sleep and wake problems as well.

This guide works from the most likely causes down. You will stop Windows from power-managing your adapter into oblivion, get the right driver installed, and tune the wireless settings that actually matter.

Why this happens

  • Windows turns off the Wi-Fi adapter to save power: The default power management setting lets Windows kill the wireless radio during light use, and buggy drivers fail to wake it cleanly — the number-one cause of random drops.
  • Immature ARM64 or Wi-Fi 7 drivers: First-generation drivers for Snapdragon X Wi-Fi, Intel BE200/BE201, and similar new radios had disconnect bugs that updates are still fixing.
  • Windows Update replacing a stable OEM driver: A generic driver pushed over your laptop maker’s tested version can reintroduce drops overnight.
  • 6 GHz band instability: Early Wi-Fi 6E/7 drivers on new platforms mishandle the 6 GHz band or band steering, dropping while hunting for a “better” band.
  • Router incompatibilities: Aggressive band steering, WPA3 transition mode, or crowded channels on the router side can knock these new adapters offline.
  • Corrupted network stack: TCP/IP or Winsock corruption from VPN clients, bad updates, or failed driver installs causes drops that survive reboots.
  • Interference and range: USB 3 docks, Bluetooth, and microwaves on 2.4 GHz, plus weak signal at distance, make marginal connections drop instead of slowing down.

How to fix it

Work through these in order — diagnose first, then act.

Fix 1: Stop Windows from power-managing the Wi-Fi adapter

This single setting fixes more Copilot+ Wi-Fi drops than everything else combined, so start here.

  1. Press Win + X and open Device Manager.
  2. Expand Network adapters, right-click your Wi-Fi adapter, and choose Properties.
  3. Open the Power Management tab and uncheck “Allow the computer to turn off this device to save power,” then click OK.
  4. Go to Settings > System > Power & battery and set Power mode to “Best performance” while testing, then reboot.

Fix 2: Install the correct Wi-Fi driver from your laptop maker

The OEM driver is validated against your exact hardware; the generic one is a gamble.

  1. In Device Manager, note the exact Wi-Fi adapter name under Network adapters.
  2. Visit your laptop maker’s support page (Dell , HP , or Lenovo ) and download the latest Wi-Fi driver for your exact model.
  3. In Device Manager, right-click the adapter, choose “Uninstall device,” and check “Attempt to remove the driver for this device” if offered.
  4. Install the downloaded OEM driver and reboot.
  5. If drops began after a Windows driver update, use Properties > Driver > “Roll Back Driver” instead, then pause driver updates for a few weeks.

Fix 3: Lock the adapter to a stable band

Band hopping between 2.4, 5, and 6 GHz is a classic drop trigger on new drivers.

  1. In Device Manager, right-click the Wi-Fi adapter, choose Properties, and open the Advanced tab.
  2. Find “Preferred Band” (or “Band”) and change it from Auto to “5 GHz” — the most stable band on current Copilot+ drivers.
  3. Find “Roaming Aggressiveness” and set it to “Lowest” or “1. Lowest” so the adapter stops hunting for marginally better access points.
  4. Reconnect to your network and test for a full day before declaring victory.

Fix 4: Reset the Windows network stack

When the driver is fine but drops persist, the network stack itself may be corrupted — this rebuilds it.

  1. Go to Settings > Network & internet > Advanced network settings > Network reset.
  2. Click “Reset now” and confirm, then let the laptop reboot.
  3. Reconnect to your Wi-Fi network and re-enter the password.
  4. If you use a VPN, reinstall its client afterward, since the reset removes its virtual adapters.
  5. Retest for a day; if drops continue, the cause is almost certainly driver or router-side.

Fix 5: Tune the router side

Sometimes the laptop is fine and the router is mishandling the new adapter — a few router tweaks can end the drops.

  1. Log in to your router’s admin page and check for a firmware update; install it.
  2. If band steering keeps kicking the laptop between bands, give the 5 GHz band its own SSID and connect the laptop only to that.
  3. Try switching WPA3 or “WPA2/WPA3 transition” mode to plain WPA2-AES, which older and newer adapters alike handle reliably.
  4. Set the 5 GHz channel to a fixed, uncongested channel (36, 40, 44, or 48) instead of Auto, and test closer to the router to rule out weak signal.

Fix 6: Rule out interference and check for deeper faults

If everything above failed, verify the problem is really wireless — not something stranger.

  1. Disable Bluetooth temporarily; on some Copilot+ models the Bluetooth and Wi-Fi radios interfere on 2.4 GHz.
  2. Move USB 3 drives and docks away from the laptop, since USB 3 can radiate 2.4 GHz noise.
  3. Test on a completely different network (phone hotspot) — stable there means your router is the problem.
  4. If drops happen even on a hotspot with the OEM driver, back up and try a network reset plus clean driver reinstall once more.
  5. Persistent drops across networks and drivers point to a faulty wireless card — contact support while under warranty. If video apps also misbehave, read about DaVinci Resolve on ARM Windows laptops for app-side context.

Closing

Wi-Fi drops on a Copilot+ PC almost always come down to power management, the wrong driver, or band-hopping — in that order. Disable the adapter’s power saving, install the OEM driver, and lock the band, and most laptops stay connected for days. Note which driver version works, because Windows Update loves to replace it; update on your schedule, not Microsoft’s.

Frequently asked questions

Why does my Copilot+ PC disconnect from Wi-Fi but other devices stay connected?
This almost always points to your laptop’s Wi-Fi driver or power management, not your router. Other devices staying online rules out the network itself. Copilot+ PCs are known for aggressive power-saving on the wireless adapter and early driver bugs on new chip platforms.
Can Windows power settings really drop my Wi-Fi connection?
Yes, and it is the most common cause. Windows may turn off the wireless adapter to save power, especially on battery, and buggy drivers fail to wake it cleanly. Disabling that behavior in Device Manager stops most random disconnects.
Should I use the Wi-Fi driver from Windows Update or my laptop maker?
Start with your laptop maker’s driver — it is validated for your exact model. Windows Update sometimes pushes a newer but untested generic driver that reintroduces disconnects. If disconnects start right after an update, roll back to the OEM driver.
Do Wi-Fi 6E and Wi-Fi 7 cause extra problems on Copilot+ PCs?
They can. Early 6 GHz drivers on new Copilot+ platforms had stability bugs, and some routers handle band steering poorly. Locking your connection to the 5 GHz band in the adapter’s advanced settings often fixes it.
