Why Wi-Fi drops after wake
Intel AX211 Wi-Fi adapter enters Deep Power Down state during sleep and the Wi-Fi driver does not complete the adapter reinitialization within the Windows connection timeout on wake, causing the connection to appear disconnected even though the router and SSID are within range on the Dell G15 5530
Dell G15 5530 BIOS power management configures the Intel AX211 PCIe lane to enter D3cold state during sleep, which requires a longer reinitialization time than the default Windows connection timeout allows
Intel AX211 Wi-Fi driver power management settings allow Windows to power off the adapter during sleep, but the driver does not correctly recover the SSID authentication on wake without a manual Wi-Fi toggle
Fixes
Disable Wi-Fi Adapter Power Management: Open Device Manager → Network adapters → Intel Wi-Fi 6E AX211. Right-click → Properties → Power Management tab. Uncheck Allow the computer to turn off this device to save power. Also open Control Panel → Power Options → Change advanced power settings → Wireless Adapter Settings → Power Saving Mode and set to Maximum Performance. These two settings prevent the AX211 from entering the deep power state that causes the post-wake reconnection failure on the Dell G15 5530.
Update Intel AX211 Driver from Dell Support: Download the Intel Wi-Fi 6E AX211 driver for the Dell G15 5530 from Dell Support. The Dell-certified Intel AX211 driver includes sleep-wake reconnection optimizations and SSID authentication retry parameters for the i7-13650HX Raptor Lake-HX platform. A newer Intel AX211 driver often includes specific fixes for post-sleep reconnection delays that affect Windows 11 Modern Standby sleep behavior on gaming laptop platforms including the Dell G15 5530.
Per Nabil Ariffin, university student using Dell G15 5530 i7-13650HX for online classes and gaming: “Wi-Fi disconnected every time the Dell G15 5530 woke from sleep. Had to toggle Wi-Fi off and on to reconnect. Disabled the Allow the computer to turn off this device setting on the Intel AX211 in Device Manager. Wi-Fi now reconnects automatically within 2 seconds of waking from sleep with no manual toggle needed.”
Fix: Update Dell G15 5530 BIOS
Download the latest BIOS for the Dell G15 5530 (Model P117F) from Dell Support. BIOS updates include Intel PCH PCIe power management firmware for the i7-13650HX platform that controls the D3cold sleep state depth and PCIe lane restoration timing for the AX211 Wi-Fi adapter. An outdated BIOS can configure the AX211 PCIe lane to require a longer restoration time than the current Intel AX211 driver expects, causing the driver to timeout the reconnection attempt and report Wi-Fi as disconnected after sleep on the G15 5530.
Frequently Asked Questions
Why does Wi-Fi disconnect after wake on Dell G15 5530?
Intel AX211 adapter power management allowing the adapter to enter deep power state during sleep, Intel AX211 driver not completing SSID re-authentication within Windows connection timeout, or BIOS PCIe power management causing longer than expected AX211 reinitialization. Disable AX211 adapter power management, set Wireless Adapter to Maximum Performance, update Intel AX211 driver from Dell Support, and update BIOS.
Does Dell G15 5530 use Wi-Fi 6 or Wi-Fi 6E?
The Dell G15 5530 uses the Intel AX211 adapter which supports Wi-Fi 6E with 2.4GHz, 5GHz, and 6GHz band connectivity. Wi-Fi 6E 6GHz band provides lower congestion and higher throughput for gaming applications when connected to a Wi-Fi 6E router. The Intel AX211 also supports Bluetooth 5.3 via the same combined radio chipset. Both Wi-Fi 6E and Bluetooth require the Intel AX211 driver from Dell Support for full feature support on the Dell G15 5530 i7-13650HX.
Can I prevent Wi-Fi from disconnecting by using Hibernate instead of Sleep?
Yes. Hibernate (S4) saves the system state to the SSD and fully powers off, which eliminates the AX211 sleep-wake reconnection issue. When the Dell G15 5530 resumes from Hibernate, it performs a cold boot that correctly initializes the AX211 Wi-Fi adapter including full SSID authentication. Hibernate takes slightly longer to resume than sleep but provides guaranteed Wi-Fi connectivity immediately after resume, unlike sleep where the AX211 may take additional seconds to reconnect.
Why does Wi-Fi disconnect on Dell G15 5530 only on battery power?
On battery power, Windows applies the Balanced or Power Saver power plan which uses more aggressive Wi-Fi adapter power saving settings than when plugged in. The AX211 enters a deeper power state on battery, increasing the sleep-wake reconnection time. Switch the battery power plan to High Performance or Balanced and change Wireless Adapter Settings to Maximum Performance for both On battery and Plugged in power plan states to prevent battery-only Wi-Fi disconnect after wake.
Conclusion
Wi-Fi disconnects after wake on the Dell G15 5530 i7-13650HX is fixed by disabling the Intel AX211 adapter power management in Device Manager, setting Wireless Adapter Settings to Maximum Performance in Power Options, updating the Intel AX211 driver from Dell Support for sleep-wake reconnection improvements, and updating BIOS for PCIe AX211 power state restoration firmware fixes. Disabling the Allow the computer to turn off this device power management setting on the Intel AX211 in Device Manager is the fastest and most reliable single fix for post-sleep Wi-Fi disconnection on the Dell G15 5530.
