Wifi very slow after iOS 6.1 upgrade
Per iOS 6.1 I had no problems with my phones wifi. After the upgrade however the phone will connect to it but data transmission is extremely slow. Speed tests show that my connection speed on wifi is under 2Mb as where before the upgrade it was around 30. Mail will not download now either without turning off wifi and going to lte. Have also noticed that lte will randomly turn off and go to 4g while I am using it. The phone usually then goes to no signal and then back to full.
iPhone 5, iOS 6.1
