iPhone 17 Pro Max connectivity and buffering issues

Hi all,

I purchased an iPhone 17 Pro Max in February and have been experiencing ongoing connectivity issues. The device struggles to connect to WiFi and frequently remains on 4G or 5G instead. Bluetooth connectivity is also very unreliable, and videos consistently buffer across multiple media platforms.

I previously used an iPhone 15 Plus and did not experience any of these issues. I have a high quality WiFi system at home, and all other family members connect without any problems. I have also noticed the same issue when using WiFi in other households. The iPhone 17 Pro Max rarely connects successfully, and video buffering is a constant problem.

Overall, I have been very unhappy with the performance so far. I do not use a large number of apps. My usage is mainly limited to work emails and light browsing on media sites.

I would appreciate any advice or suggestions you may have.

Thank you.

iPhone WiFi Issues on YOUR Network:

Seems to pertain to only YOUR network.

A. Turn Off ALL VPNs:

Are you using a VPN here? If so, turn it off. If you have no requirement for one (i.e. for school or work), then delete ALL of your VPNs:

B. Restart your Router:

Power off your router for 30 seconds, and then power it back on.

C. Force Restart your iPhone:

Go Here: Force restart iPhone - Apple Support

D. Update your iPhone:

See if you can update your iPhone. Aside from updating from the iPhone, itself, you can do so using Cellular and a computer. iOS26.4.1 is the most-recent iOS version release that is compatible with your iPhone model (iPhone 17Pro Max). So, see if that is what is installed: Settings > General > About > iOS Version

Cellular: Use an iPhone 12 or later, that is using 5G, in order to update over Cellular - User Tip

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update.
