Dell XPS 17 9730 WiFi 6E Slow on 6GHz Band Windows 11
Your Dell XPS 17 9730 WiFi 6E speed on a WiFi 6E router is disappointing – you are achieving WiFi 5 or WiFi 6 speeds rather than the 1-2Gbps expected from the 6GHz band. The Intel AX211 adapter is connecting to 5GHz instead of 6GHz, or the driver is not optimally configured for 6GHz operation.
This guide covers Intel AX211 driver settings, 6GHz band configuration, and router setup to achieve full WiFi 6E speeds on the Dell XPS 17 9730 in Windows 11.
“XPS 17 9730 only got 450Mbps on my WiFi 6E router while my phone got 1.2Gbps on the same network. Updated Intel AX211 driver from Dell Support and set Preferred Band to 6GHz. Now getting 1.8Gbps.” – Amirul Haziq, data engineer from Bangsar South

Why WiFi 6E Is Slow on Dell XPS 17 9730
The Dell XPS 17 9730 with Intel AX211 supports 6GHz WiFi 6E but defaults to connecting to the strongest available band, which is often 5GHz due to better range. On 5GHz the adapter uses WiFi 6 (not WiFi 6E) and achieves WiFi 6 speeds rather than WiFi 6E speeds. The 6GHz band must be explicitly preferred or a dedicated 6GHz SSID must be configured on the router to get full WiFi 6E throughput.
- Intel AX211 connecting to 5GHz instead of 6GHz due to stronger signal on 5GHz
- Intel AX211 driver Advanced settings not configured to prefer 6GHz band
- Router 6GHz channel width set to 80MHz limiting maximum throughput
- Intel AX211 driver version outdated – 6GHz 160MHz mode not optimally enabled

Fix 1 – Set Intel AX211 Preferred Band to 6GHz
Open Device Manager, expand Network Adapters, right-click Intel Wi-Fi 6E AX211. Select Properties – Advanced tab. Find Preferred Band and set to 6GHz. Also find Channel Width for 6GHz Band and set to Auto (allows 160MHz). Find 802.11ax Mode and ensure it is Enabled. Click OK. Windows WiFi will now prefer the 6GHz band on WiFi 6E routers, achieving full WiFi 6E throughput.
Fix 2 – Update Intel AX211 Driver from Dell Support
Go to dell.com/support, enter the XPS 17 9730 service tag, and download the Intel Wi-Fi 6E AX211 driver from the Network section for Windows 11. Dell-qualified AX211 drivers version 22.230 or later include improved 6GHz band steering and 160MHz stability that increase achievable 6GHz throughput and reduce connection dropout on the 6GHz band.
Create a Dedicated 6GHz SSID on Router
Log into the router admin panel and create a separate SSID for the 6GHz band (such as HomeNetwork-6GHz). Connect the Dell XPS 17 9730 specifically to this network. A dedicated 6GHz SSID bypasses band steering and guarantees the AX211 operates only on 6GHz. Set the 6GHz channel width to 160MHz in router settings for maximum WiFi 6E throughput.

Fix 3 – Check Router Location for 6GHz Range
The 6GHz band has shorter range than 5GHz due to higher frequency signal attenuation through walls and distance. For maximum WiFi 6E performance, the Dell XPS 17 9730 should be within 5-8 meters of the router with minimal obstructions. At greater distances, the AX211 may fall back to 5GHz or connect on 6GHz with reduced channel width, limiting throughput. Moving closer to the router dramatically improves 6GHz WiFi 6E performance.
Fix 4 – Disable 2.4GHz and 5GHz on AX211 Temporarily
In Intel AX211 Advanced properties in Device Manager, find 802.11b or 802.11a Mode settings and disable 2.4GHz and 5GHz bands. With only 6GHz available, the adapter must connect to 6GHz or not connect. After confirming maximum speed on 6GHz, re-enable the other bands. This diagnostic step confirms whether 6GHz is achievable from your current location and validates the router 6GHz configuration.
Frequently Asked Questions
Why is WiFi 6E slow on Dell XPS 17 9730?
Intel AX211 is connecting to 5GHz instead of 6GHz. Set Preferred Band to 6GHz in Device Manager Advanced settings and update the AX211 driver from Dell Support.
How do I connect Dell XPS 17 9730 to 6GHz WiFi 6E?
Device Manager – Intel AX211 – Advanced – Preferred Band – 6GHz. Or connect to a dedicated 6GHz SSID on the router. Update driver from Dell Support.
Does Dell XPS 17 9730 support WiFi 6E?
Yes – Intel AX211 supports 6GHz WiFi 6E up to 2.4Gbps on 160MHz channels. Requires WiFi 6E router for 6GHz access.
What WiFi card does Dell XPS 17 9730 have?
Intel Wi-Fi 6E AX211 (Gig+) with Bluetooth 5.3. Supports 6GHz, 5GHz, and 2.4GHz.
Conclusion
WiFi 6E slow on Dell XPS 17 9730 in Windows 11 is resolved by setting Intel AX211 Preferred Band to 6GHz in Device Manager Advanced settings and updating the AX211 driver from Dell Support. A dedicated 6GHz SSID on the router with 160MHz channel width bypasses band steering for consistent WiFi 6E connections. Proximity to the router and a clear line of sight maximizes 6GHz signal quality for the highest throughput.
