My connection quality on my home wifi is quite sketchy on my iPhone only. There's quite a lag when pulling up simple apps like Facebook, Twitter, Instagram...etc. it's takes forever for those apps to update with the latest info. I can switch off wifi and go to data and apps update immediately, yet my kid can be gaming online on wifi on Xbox with no problem. It's a real head scratcher. I've done the obvious like reset my modem and reset the network settings on my phone but to no avail
