My iPhone 6 internet on wifi is painfully slow & always has been.
I've had my iPhone 6 since about when they came out, and from day 1, my internet (when I'm connected to wifi) has been just painfully slow- half the time it just gives up, and says Safari can't load the page. Any app I have that is meant the access the web, twitter, instagram, etc., is extremely slow 75% of the time... but only when I'm connected to wifi!
And I know it's not my wifi that's slow, because it doesn't matter where I am (work, home, gym), it's ANY wifi, that makes my phone's internet slow.
So..... what's up with that? I think it's slower than my iPhone 4 was..
iPhone 6, iOS 9.0.2
