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 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?
 
What is your IP address and gateway when on wired, and is it within the same range when on wireless?

BTW, not much love for Asus on here. Shady security history, poor RMA support, and wild marketing claims.
 
My wired and wireless networks are both using the same default gateway (e.g., 192.168.xx.1), and the only difference between them is the last few digits of the IP address assigned to each device (e.g., 192.168.xx.xxx for wired and 192.168.xx.yyy for wireless). So both in same range.

Yes I can ping the gateway and 8.8.8.8. When I do a nslookup on bbc I get:
Server: dns.google
Address: 8.8.8.8
Non-authoritative answer:
Name: bbc.co.uk
Address: 151.101.129.81
 
Are you using any features on the iphones like icloud private relay, limit address blocking, wifi assist, etc?

I'd see if they are able to work just with a forced native wireless connection.

That's a good shout, forgot iPhones do this now. I would also turn off the AI Protection the Asus router has, it's mostly useless and could also be affecting the iPhones.

No on my laptop. As my mobile is not getting an internet connection I’m unable to connect on anything.

But is it getting a LAN connection? Based on your previous replies, DHCP is working so can you use your iPhone to ping your gateway? And if that works, can you ping 8.8.8.8? I’m trying to help you determine if it’s a DNS issue.
