Unable to connect to Wi-Fi on iPhone 17 Pro Max after iOS 26.0.1 update

I've had the same issue, however, it also depends on the Router settings as well. But I think the problem is directly to the network chip inside or a software issue. I own an Asus GT-AX1100 Gaming router, which is a Wi-Fi 6 router, and have noticed that I had to turn off AX mode and set the encryption from WPA3 to WPA2/WPA3 just to get my iPhone 17 Pro Max to connect to my 5Ghz WiFi. I'm sure it's different for everyone else. I had no issue with my old iPhone 13 Pro Max or my brother's iPhone 16 Plus. I don't use VPN, and have tried a factory reset, network reset, and restarting the iPhone many times.

Hi,

My issue is even worst. Purchased the iPhone 17 Pro and it will not connect to my TP-Link.

Did reset etc and updated to iOS 26.0.1. Phone was wiped at Apple store and still no luck was then given a replacement and no joy as well.

So the issue is with my secure router, if I set it to non-secured it works.

I think many customers may have to buy a new router because of the new iPhone; all my other devices connect fine.

Yes the TP-Link was an old router so I purchased a new TP-Link (WiFi 6) and it worked.

You have all answered this question, excessive and intrusive security, on routers and on iphones (VPN), has its consequences.

I would be embarrassed demanding a replacement iphone 17 pro only to find it was my router. Trying someone else’s router would have pinpointed the problem.

Do you have a VPN installed on your phone, whether it's used or not?

I have been travelling for two weeks now and our iPhone 17 Pro ( my husbands and mine) do not detect any WIFI in any of the places we have stayed in. Our iPads detect the WIFI without a problem. The only way around this we have found, is for someone with an android phone on the same WIFI to generate a QR Code which we then scan with our iPhone 17 Pro. Surely there must be a setting on the iPhone to allow it to recognise the WIFI signal?

I'm seeing same issue with my WiFi and Bluetooth being unstable. All other devices are connected to same WiFi and they stay stable, whereas 17 Pro Max goes on and off. Have to reconnect to WiFi and wait for it to go online. Nightmarish!!!

Your solution that you have posted a few times elsewhere may have some relevance there but it is not relevant in this case, the problem was old routers.

No I do not have VPN installed.

How did you solve it? Was the problem TP-Link?

I have probably the same issues.

Thx

Unable to connect properly to Wi-Fi & Cellular on iPhone 17 Pro from starting onwards and not yet solved after iOS 26.1 update. Still the problem persist.
