Wi-Fi not working after iOS 18.6 update on iPhone and iPad

I downloaded the 18.6 new iOS update on my iPads and cell phone and all three of them will not get on the Wi-Fi and connect the only way I can get on the Internet is on my cell phone now with out Wi-Fi turned on!! This is just awful. Is anyone else experiencing this?

I resolved mine through VPN settings as well. Verizon offers multiple VPN settings and it looks like one of them causes the iPhone to appear to disconnect from WiFi; mine probably reverted to this VPN settings after the update. My phone works with a different VPN as well as no VPN.


To fix, go to Settings>VPN. Then pick your desired VPN and ensure that it connects properly and works.

I updated my phone to iOS 18.1.6 this morning. I can't connect to wifi... anywhere!


I've restarted my phone multiple times, I've reset the network settings, I've restarted our router... I cannot connect to wifi... well the wifi menu says i'm connected, BUT there's no little wifi fan symbol in the top right on my phone and I am NOT connected to the internet. I can't even check for further updates because I'm not connected to the internet!!! My cellular data seems to be patchy too...


What has Apple done to my phone??? I refuse to update my laptop, work phone or iPad until this is fixed!!!


So I finally was able to turn my VPN on and connected to wifi. But this is simply not good enough that this is the case!

Having similar issues. I didn’t install 18.6.2 immediately and now am worried that my phone might be compromised somehow? I have Photon VPN installed on my phone, but I tried switching wifi off (which switches the VPN off) and connecting to the 5G network, but still no go. Do I have to physically take the VPN app off my phone and reinstall?

Unless you are perpetually geo-shifting, an added VPN is just a way for vendors to collect personally-identified metadata and various other data in exchange for added connection overhead and negligible added security.


And if you are perpetually geo-shifting, the personally-identified metadata collection is quite possibly still active.


Some of the no-logging VPNs were caught logging a while back when the “non-existent “ logs were found exposed on the ‘net, too.


Too many VPNs are all too similar to malware, albeit with an end-user license agreement.

Nobody thinks a VPN as a massive privacy leak, and as a massive unnecessary overhead, either.


VPNs badly solve a problem* that hasn’t existed for a decade or so, but badly solve it in a way perfect for personally-identified metadata and data collection.


Outside of geo-shifting for website or CDN testing or otherwise, I wouldn’t use a VPN, and I’d expect metadata to leak when geo-shifting.



*This reply does not apply to VPNs used to access the internal networks of affiliated organizations, and which is a useful capability.
