On wifi, internet on my iphone 14 pro is slow, but my ipad works fine

By that I assume you mean just standard iOS 16.3.1, no installed apps.

OK, only 2 things you can do:

Reset the router to factory settings, usually with a pin in a little hole for 10 seconds, and

iphone, Settings, General, Transfer or reset iohine, Reset, Reset network settings.

If that has no effect contact Apple Support to have it diagnosed.

There might be some benefit in backing up (which you will need to do if the phone needs looking at) then restoring to factory settings and restoring the backup.

See my reply above yours regarding profiles.

After that there's a progressive hierarchy of things you can try

First thing I advise is to try a Forced restart 

Force restart iPhone – Apple Support (UK) 

If no better you could Backup, restore to factory, then restore from the backup:-  

If necessary set up without restoring backup and test at that point, erase again, then restore from the backup:-  

(If the phone needs attention you will have to do this anyway) 

(If you can import your media to Photos or iTunes in a computer and copy important documents to a cloud server it will give you some resilience in case the restore from backup fails, or you need to ditch the backup and start as new.)

See here for the resources you need. Allow a couple of hours:

 Otherwise arrange a repair for hardware failure

Hi, I’m having exactly the same issue with my IPhone 8S. My iPad works fine, but at home, only certain webpages will load.

I have reset my Wi-Fi router, reset network settings on my phone, removed all browsing history and cookies, there is no VPN activated.

i have tried just about everything, but can’t seem to solve the problem

Hi, thanks so much for your help and advice, it’s much appreciated. I’ll go and try the things you’ve listed.

I didn’t receive any notification for your reply. I’ve had to log back into the forum to find out.

Thanks again for your detailed help and advice

Are you running security or VPN apps?

You're very welcome hope it continues.

PS we have been having forum problems. Did either of you get a notification email about my replies?

Thank you.

You're very welcome.

Thank you, we don't get emsils from Using iPhone section either, but I had an idea that the original Authors might. We'll see...
