iPhone 15

[CMac1977]

I got my son got a new iPhone 15 for his Xmas through Sky and connection to our  WiFi at home on it is very weak, pretty much unusable.

Not had any problems with the WiFi before (Plusnet) everything else which is connected to it works fine.

He is also unable to log into Snapchat for this reason and he keeps getting an error code C14A.

@CMac1977 The following may or may not help but its worth giving it a go , To turn off iCloud+ Private Relay - Settings > Apple ID page (select your name at the top) > ICloud > go down to iCloud+ section > Private Relay > toggle off.

It may also be worth seeing if turning off WiFi assist helps.
