Q: WiFi slows down after iPhone 6s connected
Good day everyone.. (not good for me obviously)
I have questions about my iPhone 6s (iOS 9.3.2) connecting to my TP-Link Router (Model No. TL-WR740N / TL-WR740ND) and its performance.
Whenever I connect my iPhone to the WiFi network, suddenly the ping get very high ( from 13ms to suddenly 2000ms ), and after some seconds, it goes RTO. The ping then stays around 2000ms, 1000ms but with a lot of RTOs. I checked the ping on my laptop, and all other devices connected to WiFi are also RTO. I tried to disconnect all other devices except my laptop and my iPhone and still RTO. This problem lasts for 20 - 30 mins, sometimes longer. once I disconnected my iPhone, it all went back to normal (13ms).
I tried connecting ONLY my iPhone to the WiFi and still the same, I even got hard time just to open Google!
My iPhone isn't connected through bluetooth or USB, not being charged, the distance between my iPhone and the router is < 3meters.
I already checked some articles and some questions too.
- iPhone slows down entire home network
- https://discussions.apple.com/thread/6734990?start=0&tstart=0
- WiFi connection problem (iPhone to TP-Link router)
according to those articles, It may be because of :
- iCloud automated backup.
- Photo backup.
- Auto app store update.
- router problem
the problem is, my iPhone is fresh from the box, I don't even have a lot of apps, I don't even use iCloud, I disable auto app store update, I disable location, and I already follow all the possible solution from the third article (changing router setting) and still the same.
I've tried restarting my router, restarting my iPhone, change channel width of the router (auto, 20Mhz, 40Mhz), change mode (11gbn, 11g only, 11b only, 11n only), enable/disable QSS, enable/disable WMM and still the same.
What could be the cause of this problem?
Your help is appreciated, Thank You.
iPhone 6 Plus, iOS 9.3.2
