iPhones Unable to Connect to Wi-Fi on ASUS Router

Hardware Setup:

• Modem: DrayTek Vigor 167

• Router: ASUS RT-AX86U Pro

Background:

I recently switched from my Sky Broadband Hub to a DrayTek Vigor 167 modem and an ASUS RT-AX86U Pro router. The internet connection is working fine through Ethernet, and my laptop connects to Wi-Fi without any issues. However, iPhones are able to connect to the Wi-Fi network but display “No Internet Connection.” This issue occurs across multiple iPhones, so it’s probably not device-specific.

What I’ve Tried So Far:

General Setup & Connectivity Checks:

• Confirmed that the modem is in bridge mode and the router is handling DHCP.

• Verified that the ASUS router shows Internet Status: Connected and has a valid WAN IP.

• Checked that my laptop connects to Wi-Fi and gets internet access successfully.

• Ping tests from the router to external sites (like 8.8.8.8) work fine.

Troubleshooting Wireless & DNS:

• Disabled Wi-Fi 6 (802.11ax) mode.

• Tried different DNS servers (Google’s 8.8.8.8 / 8.8.4.4 and Cloudflare’s 1.1.1.1).

• Checked Sky Shield settings to make sure it isn’t blocking access.

• Disabled Protected Management Frames (PMF).

• Disabled Airtime Fairness and Smart Connect.

• Tested both 2.4GHz and 5GHz bands separately.

• Manually set static DNS settings on the iPhone.

Additional Tests:

• Checked for firmware updates on both the ASUS router and the DrayTek modem.

• Confirmed IP settings on the iPhone (it gets an IP address from the router but no internet).

• Reset network settings on iPhone.

Current Status:

• Ethernet works.

• Laptop on Wi-Fi works.

• iPhones connect to Wi-Fi but show “No Internet Connection.”

• No obvious settings seem to be blocking access.

Has anyone experienced this issue with an ASUS RT-AX86U Pro or similar setup? Any suggestions on what else to check?
