iPhone 6 extremely slow WiFi
All,
I am having ongoing issues with my iPhone 6 and home WiFi connection. The connection is either extremely slow to load web pages (or data in apps), or cannot load them at all. The issue is intermittent, but seemingly has an issue more often than not. Reverting to 4G/LTE connection results in the pages immediately loading.
The iPhone is showing 3 bars of WiFi signal strength. The underlying internet connection itself is strong; at the same time as the iPhone cannot load web pages, my Samsung tablet is returning ping 4ms, download 65 mbps and upload 95mbps using Ookla speed test and has no issues with basic web browsing. The iPhone won't even get past the "preparing" status in the same app at the same time as the Tablet is working successfully. Likewise the laptop, connected by WiFi, has no connection issues and returns great results on the Ookla website.
On the odd occasion that the iPhone DOES work on WiFi at the same time as the tablet (or in the case of a speed test, immediately after), it will often return results along the lines of 30ms ping, 9mbps download, significantly slower than the tablet. Occasionally it does a little better, such as just now when it returned ~32mbps for upload and download, right after the laptop returned 90/70 respectively.
I have already been through multiple changes to try to make this connection work, including:
(1) Resetting Network Settings on iPhone (several times)
(2) Buying new (upgraded spec) wireless router
(3) Repositioning wireless router
(4) Removing iPhone case
(5) Restarting iPhone (several times)
The iPhone is running the latest software update (8.4.1 12H321), but this issue has been present for approximately 2 months.
I cannot be certain, but it is possible that the issue is just with my home WiFi connection, as when I am using other WiFi networks (e.g. at work) I am not noticing the same latency / non-loading of pages, although usage at work is much less.
Any advice would be appreciated as I am just about at my wit's end!
Many thanks
iPhone 6, iOS 8.4.1
