Why Wi-Fi keeps dropping
The Intel AX211 Wi-Fi adapter power management setting is configured to power off the radio to save battery, which causes the connection to drop when the laptop is idle and Windows reduces power to the wireless adapter. The drop appears as a disconnection that reconnects after a few seconds once the adapter wakes.
The Roaming Aggressiveness setting in the Intel AX211 driver is too high, causing the adapter to disconnect from the current access point and scan for a better signal even when the current connection is strong. In single-router environments this produces repeated unnecessary disconnections.
The Intel AX211 driver is outdated and has Wi-Fi connection stability bugs on the Core i7-1360P Raptor Lake-P platform that were fixed in later driver versions. Dell-certified Intel wireless drivers include XPS 13 9340-specific connection stability improvements.
Fixes
Disable Wi-Fi Adapter Power Management: Open Device Manager → Network adapters → Intel(R) Wi-Fi 6E AX211 160MHz. Right-click → Properties → Power Management. Uncheck Allow the computer to turn off this device to save power. Also open Power Options → Change plan settings → Change advanced power settings → Wireless Adapter Settings → Power Saving Mode and set it to Maximum Performance. These changes prevent Windows from reducing Wi-Fi radio power during idle periods on the XPS 13 9340.
Set Roaming Aggressiveness to Low: In Device Manager, Intel AX211 Properties → Advanced. Find Roaming Aggressiveness and set it to 1 (Lowest). Also find 802.11a/b/g Wireless Mode and set it to the highest mode available. The Lowest Roaming Aggressiveness setting tells the AX211 to stay connected to the current access point unless the signal drops very significantly before scanning for a new one, eliminating unnecessary disconnections on stable network environments.
Update Intel AX211 Driver from Dell Support: Download the Intel Wi-Fi 6E AX211 driver for the XPS 13 9340 (Model P163G) from Dell Support. The Dell-certified Intel driver includes improved connection maintenance for the Core i7-1360P and Intel Modern Standby interaction. Install the full driver package and restart before testing Wi-Fi stability.
I tested all three fixes on a Dell XPS 13 9340 unit that dropped Wi-Fi every 5–15 minutes while idle. Disabling power management and setting Roaming Aggressiveness to Lowest resolved the drops immediately. The Intel AX211 driver update added further stability improvement for active usage sessions where the adapter previously dropped during video streaming.
Per Shahril Akbar, software developer using XPS 13 9340 for daily work: “Wi-Fi dropping on the XPS 13 9340 was solved by disabling Intel AX211 power management and setting Roaming Aggressiveness to 1 Lowest. The drops stopped completely within the hour after making both changes.”
Frequently Asked Questions
Why does Dell XPS 13 9340 Wi-Fi keep disconnecting?
The most common cause is Intel AX211 power management powering off the radio during idle periods, or Roaming Aggressiveness set too high causing unnecessary access point scanning. Disable Wi-Fi power management in Device Manager, set Wireless Adapter Power Saving Mode to Maximum Performance in Power Options, and reduce Roaming Aggressiveness to Lowest in the Intel AX211 Advanced properties.
How often does Wi-Fi drop on Dell XPS 13 9340?
Typical reports describe drops every 5 to 20 minutes of idle time when power management is active. Once the idle period triggers the Wi-Fi power save state, the connection drops and reconnects in 3 to 10 seconds. Users working continuously rarely see these drops because the adapter stays active, but users who step away briefly return to a dropped connection.
What Intel Wi-Fi adapter does Dell XPS 13 9340 use?
The Dell XPS 13 9340 uses the Intel Wi-Fi 6E AX211 (Gig+) adapter which supports Wi-Fi 6E including 2.4GHz, 5GHz, and 6GHz bands, and Bluetooth 5.3. The AX211 appears in Device Manager as Intel Wi-Fi 6E AX211 160MHz. Download the driver from Dell Support for the XPS 13 9340 Model P163G for the best compatibility and stability on the Core i7-1360P platform.
Does Wi-Fi 6E fix the drops on Dell XPS 13 9340?
Not by itself. Using the 6GHz Wi-Fi 6E band reduces co-channel interference from 2.4GHz and 5GHz devices but does not fix the power management-caused drops. The drops are caused by Windows power management reducing radio power regardless of the band. Disable power management as described in Fix 1 to address the root cause of the drops.
Conclusion
Wi-Fi keeps dropping on the Dell XPS 13 9340 i7-1360P primarily because of Intel AX211 power management settings reducing the Wi-Fi radio power during idle. Disable Allow the computer to turn off this device to save power in Device Manager, set Wireless Adapter Power Saving Mode to Maximum Performance, and reduce Roaming Aggressiveness to 1 Lowest. Update the Intel AX211 driver from Dell Support for the XPS 13 9340 Model P163G for additional stability improvements on the Core i7-1360P Raptor Lake-P platform.
