However, a user who opened a ticket with Apple reported on\u00a0MacRumors\u00a0that the issue is with IPv4 connectivity. In the MacRumor post, the user described the issue as this:<\/p>\n \u201cDescription SYMPTOMS: Similarly, I\u2019ve also had issues with my iPhone 17 Pro Max<\/a>, and I haven\u2019t been able to hotspot to my PS5 or my friend\u2019s iPhone. This definitely started happening to me after the recent update.<\/p>\n The issue seems to affect both the iPhone 17 and the iPhone 17 Pro smartphones.<\/p>\n Source: Reddit<\/a>, MacRumors<\/a><\/p>\n

After updating to iOS 26.4, devices connected to the iPhone Personal Hotspot via Wi-Fi lose all IPv4 connectivity. IPv6 works correctly.The issue was not present on iOS 26.3.<\/p>\n
\u2013 Tethered Mac connects to hotspot successfully (DHCP assigns 172.20.10.x)- All IPv4 TCP connections fail immediately with \u201cNetwork is unreachable\u201d- IPv6 connections succeed normally- Issue affects all destinations regardless of VPN state (reproduced with and without Cloudflare WARP active)- Direct IPv4 connectivity to public IPs fails (Cloudflare, GitHub, etc.)
REPRODUCTION STEPS:
1. Update iPhone to iOS 26.4
2. Enable Personal Hotspot
3. Connect a Mac via Wi-Fi4. On the Mac, run: curl -v \u2013max-time 10 \u2013ipv4\u00a0https:\/\/github.com<\/a>\u00a0\u2192 Fails: \u201cNetwork is unreachable\u201d
5. Run: curl -v \u2013max-time 10 \u2013ipv6\u00a0https:\/\/github.com<\/a> \u2192 Succeeds\u201d<\/p>\n
