Slow WiFi on iPhone 7

Hello,


I’m experiencing an issue with my iPhone 7 on IOS 13 where the download speed on WiFi is extremely slow - 1Mbps - while my internet connection is 25Mbps. The upload speeds are generally above > 20Mbps at the same time. The issue appears to only impact my iPhone, not my other devices - MacBook Pro, 2x Apple TVs, numerous iPads, android phones, etc. This issue seems to have coincided with IOS updates around November. iPhone had been working perfectly before.


Sometimes a hard reboot will rectify the issue for a short time, but the symptom returns after a while. Hard reboot doesn’t always resolve the problem.


Wifi signals are generally good. iPhone doesn’t display same issues on 3G/LTE.

Hello vernhs,



Thanks for that info and choosing the Apple Support Communities. If I understand correctly, you are having issues with Wi-Fi on your iPhone, even after restarting. To help resolve this issue, please check for potential sources of interference, test on other Wi-Fi networks, make sure you have the recommended Wi-Fi router settings and other steps from these resources on your situation.

Hello,


Thanks for feedback. I had reviewed the router configuration recommendations previously and have applied all applicable settings on my router and access points as suggested. I do however use manual channel selection to avoid interference between my three 2.4Ghz radios and neighbours. I’ve also used Netspot to assess my WiFi signal strength and there is sufficient coverage throughout my house. The signal strength on my phone appears to be full on WiFi bars as well as other devices. Despite this, my iPhone download speed is all to often ridiculously slow. Sometimes it’s perfectly acceptable. Upload speeds are general as expected, even when download speeds are slow.
