Anyone experiencing really slow WiFi on their new iPhone 6 Plus? Mine is super slow. When I switch off WiFi, LTE works perfectly and very snappy. I didn’t have any issues with my 5s and not having issues with my iPad Air.

Hello donna , That’s mean your WiFi Network is working fine. lets troubleshoot the fault Make sure you iPhone 6+ running with latest IOS Turn of Wifi Networking Settings > Privacy > Location Services > System Services if the problem reaming same Reset Network Settings Settings > General > Reset and tap on Reset Network Settings.

Check if this iphone is also slow under other networks. If also slow, the phone has problems, if not, it’s a compatibility issue.

I hope i helped you!
