iPhone 7 Plus slow Wi-fi after iOS 12 update

Hi after updating to iOS 12 my iPhone 7 Plus and my wife’s too has really slow Wi-fi connection at home . I have tried various things to improve such as force shutdown , reset network settings , switching off wifi networking etc . It all seems to work temporarily but after a while or if I disconnect from the Wi-fi network and reconnect the Wi-fi becomes slow again . On my iPad 2017 and iPad mini 2 which have updated to iOS 12 Wi-fi speed hasn’t been affected . Any ideas?

Hello,

I found out that if I disable bluetooth from settings (not from the swipe up panel of control centre), everything get's back to normal (wifi has the desired speed). I've tested to forget all of my bt devices without any effect...tried to turn off Airdrop etc....I've found the same issue in a topic from era ios10 as well

Disappointing...

Found another thread: If you switch your wifi providing device to 5 GHz, bluetooth does not interfere (both are using 2.4 GHz band for communicating). Normally that should not be a problem (I have not met this issue with any other device than apple :-/ )

Regard,

I have exactly the same problem. I have done everything that emnems1970 has done to no avail. I was hoping with the ios12.01 update, it would have solved the problem. Using 4g, I get faster speeds over wifi at the moment.

Using the iPad with ios12, hi wifi speeds are not a problem.
