HP Pavilion Plus 16 Intel Core Ultra 7 155H WiFi 6E Not Working Fix Windows 11

The WiFi 6E 6GHz band is not connecting on your HP Pavilion Plus 16 Intel Core Ultra 7 155H – the 6GHz network does not appear in the Windows WiFi list, connection attempts to the 6GHz band fail, or the adapter only shows 2.4GHz and 5GHz networks without the 6GHz option. Intel WiFi driver updates and router configuration enable 6GHz WiFi 6E connectivity on the HP Pavilion Plus 16.

This guide covers Intel WiFi 6E driver updates, router 6GHz configuration, and wireless band selection for the HP Pavilion Plus 16 Intel Core Ultra 7 155H in Windows 11.

“Pavilion Plus 16 did not show 6GHz networks despite having WiFi 6E adapter. HP Support Assistant had Intel WiFi 6E AX211 driver update. After installing, 6GHz SSID appeared and connected at 1.2Gbps – much faster than 5GHz for video editing file transfers.” – Farouk, video editor from Bangsar South

Why WiFi 6E Does Not Work on HP Pavilion Plus 16

WiFi 6E 6GHz connectivity requires three aligned components: a WiFi 6E certified router broadcasting on the 6GHz band, a WiFi 6E adapter (Intel AX211 in the Pavilion Plus 16) with 6GHz-capable driver, and Windows 11 WiFi 6E regulatory domain support. The Intel WiFi 6E AX211 adapter hardware supports 6GHz, but an outdated Intel WiFi driver may not include the 6GHz regulatory domain database entries needed for the adapter to scan and connect to 6GHz networks. Most commonly, the Intel WiFi driver installed from HP Support Assistant is current, but the router does not have the 6GHz band enabled in its wireless settings.

• Intel WiFi 6E driver outdated – 6GHz band regulatory database not included
• Router 6GHz band disabled in router admin panel (requires manual enable for most routers)
• Router is WiFi 6 (not WiFi 6E) – 5GHz max, no 6GHz band available
• 6GHz region regulatory restriction – 6GHz band not available in all countries

Fix 1 – Update Intel WiFi 6E Driver via HP Support Assistant

Open HP Support Assistant and install Intel WiFi 6E AX211 or Intel Wireless driver update. Restart. After restart, open Settings – Network and internet – WiFi and click Show available networks. If a separate 6GHz SSID from the router is now visible (many WiFi 6E routers create separate 6GHz SSID like HomeNetwork_6G or broadcast 6GHz on the same SSID as 5GHz via band steering), select it and connect. The updated Intel WiFi 6E driver includes the latest 6GHz regulatory domain tables and improved 6GHz band scanning parameters for reliable 6GHz network discovery on the Pavilion Plus 16.

Fix 2 – Enable 6GHz on WiFi 6E Router

Log into the router admin panel (typically 192.168.1.1 or 192.168.0.1). Navigate to Wireless settings. Find the 6GHz band toggle and enable it. Routers ship with 6GHz disabled by default in many markets to reduce interference and because few devices previously supported 6GHz. After enabling 6GHz on the router, the 6GHz SSID appears within 60 seconds on devices with WiFi 6E adapters. Set 6GHz band to auto channel for automatic channel selection. WPA3 security is required for 6GHz band connections – ensure the router 6GHz band is configured with WPA3-Personal or WPA3-SAE rather than the older WPA2.

Check WiFi 6E Adapter Properties

Open Device Manager – Network adapters – Intel WiFi 6E AX211 – Properties – Advanced tab. Find Band setting or 802.11ax 6GHz Band setting. Ensure it is set to Enabled or Auto. If the 6GHz band is disabled in adapter Advanced properties, it does not scan for 6GHz networks regardless of router configuration or driver version. After enabling 6GHz in adapter properties, the adapter includes 6GHz in its active scan channels and 6GHz SSIDs appear in the available networks list within 30 seconds on the HP Pavilion Plus 16.

Fix 3 – Verify Router is WiFi 6E (Not WiFi 6)

Check the router model on the manufacturer website. WiFi 6E routers explicitly state 6GHz support in their specifications (802.11ax with 6GHz or Tri-band with 6GHz). WiFi 6 routers (without the E suffix) support only 2.4GHz and 5GHz – they do not have 6GHz capability regardless of device driver or adapter state. Common WiFi 6E routers include ASUS ZenWiFi Pro ET12, Netgear Orbi RBK863S, TP-Link Deco XE75, and similar. If the current router is WiFi 6 or older, upgrading to a WiFi 6E router is required to use the HP Pavilion Plus 16 Intel AX211 6GHz capability.

Fix 4 – Use 6GHz for File Transfers, 5GHz for Coverage

6GHz WiFi provides maximum throughput (up to 2.4Gbps theoretical with 160MHz channel width) but has shorter range than 5GHz due to higher frequency signal attenuation through walls. Use the 6GHz band when within 5-10 meters of the router without obstructions for NAS file transfers, large download operations, and video streaming at 4K. Switch to 5GHz for connectivity across rooms or floors where the 6GHz signal is weaker. On the HP Pavilion Plus 16, Windows 11 selects the strongest available signal band by default – when both 5GHz and 6GHz are available, connection may prefer 5GHz if it has stronger signal at the current laptop location.

Frequently Asked Questions

Why is WiFi 6E not working on HP Pavilion Plus 16 Intel Core Ultra 7 155H?

Router 6GHz band not enabled (most common), or Intel WiFi driver needs update. Enable 6GHz in router admin panel and update Intel WiFi driver via HP Support Assistant.

How do I connect to 6GHz WiFi on HP Pavilion Plus 16?

Intel WiFi 6E driver update via HP Support Assistant. Router 6GHz band enabled with WPA3 security. Select 6GHz SSID in Windows WiFi networks list.

Does HP Pavilion Plus 16 Intel Core Ultra 7 155H have WiFi 6E?

Yes – Intel WiFi 6E AX211 supporting 2.4GHz, 5GHz, and 6GHz for up to 2.4Gbps on 6GHz with compatible WiFi 6E router.

Why is 6GHz WiFi slower than 5GHz on HP Pavilion Plus 16?

Distance and walls attenuate 6GHz more than 5GHz. 6GHz optimal within 5-10 meters of router without obstructions. Use 5GHz for long-range room-to-room connectivity.

Conclusion

HP Pavilion Plus 16 Intel Core Ultra 7 155H WiFi 6E not working in Windows 11 is resolved by enabling the 6GHz band in the router admin panel (most common cause) and updating the Intel WiFi 6E AX211 driver via HP Support Assistant. Adapter Advanced properties 6GHz band enable in Device Manager activates 6GHz scanning when disabled in adapter configuration. WiFi 6E router (not WiFi 6) is required for 6GHz band availability. 6GHz band provides maximum throughput close to the router while 5GHz provides better range through walls for day-to-day general connectivity on the HP Pavilion Plus 16.
