Windows 11 Wi-Fi keeps disconnecting on Dell XPS 13
Your Dell XPS 13 drops Wi-Fi every few minutes on Windows 11. It's a power saving setting gone wrong. Here's how to stop it.
I know this error is infuriating. You're in the middle of a Zoom call, or maybe you're downloading a file, and suddenly the Wi-Fi icon shows a yellow triangle. Then it reconnects. Then it drops again. It happens every 5 to 10 minutes on my Dell XPS 13 running Windows 11. My router is fine — other laptops work perfectly. So why does this happen?
The root cause is almost always the power saving feature on your wireless adapter. Windows 11, by default, tells the Wi-Fi card to go to sleep when it thinks it's not being used heavily. The problem is, the card wakes up slow. Sometimes it never really wakes up right. The adapter gets confused, and boom — connection lost.
Skip all the other stuff people tell you to try, like resetting the network stack or updating drivers. The real fix is here. It takes two minutes. Let's do it.
Step 1: Open Device Manager
- Press Windows Key + X and select Device Manager from the menu.
- Or just type device manager in the Start menu search and hit Enter.
Step 2: Find your Wi-Fi adapter
- Expand Network adapters.
- Look for something like Intel(R) Wi-Fi 6E AX211 160MHz or Killer Wi-Fi 6 AX1650 — depends on your Dell XPS model. On my XPS 13 9310, it's the Intel one.
- Right-click it and select Properties.
Step 3: Turn off power saving
- Click the Power Management tab.
- Uncheck the box that says Allow the computer to turn off this device to save power.
- Click OK.
That's it. You just told Windows to stop messing with your Wi-Fi card. Restart your laptop. The drops should stop immediately.
What if it still happens?
Two things to check:
- Driver version: Open Device Manager again, right-click your adapter, select Update driver > Browse my computer for drivers > Let me pick from a list. If you see two driver versions, pick the older one. The latest Intel drivers sometimes cause this problem on Dell laptops. I'm serious — the 22.180.0.4 driver works better than the new one for me.
- Router settings: Log into your router admin page. Turn off Wi-Fi 6 (802.11ax) mode or set it to 802.11ac. Some older routers and adapters fight each other on Wi-Fi 6. It's a known quirk.
If neither helps, try this: Open Command Prompt as admin and run netsh wlan show profiles. Find your network name, then run netsh wlan delete profile name="YourNetworkName". Then reconnect fresh. That clears any corrupted saved settings.
I've seen this exact issue on dozens of Dell XPS 13 units. The power saving setting is the culprit 9 times out of 10. You'll be fine after this fix.
