For some strange reason, my wi-fi won't stay connected! It's a problem that has just started! I have a iphone 4, jailbroken 4.1 ( greenpoisOn )! Any help will greatly appreciated! Thanks in advance!
Do you use Myfi?
Try resetting network settings in the general settings. That should help.
On all wifi or just at a certain place?
Do you have a laptop or any other devices that use wi-fi at your home?
I had the same problem with my i 4 too i reset my router and everythings been good . look on the back of it for a reset button hold down for 60 secs then un plug it then unplug your modem for 30 sec plug modem back in first then wait 30 secs then plug in router and your good!! hope this helpsi really don't know! i use 3g when i'm out and about, and only wi-fi at home because my services suck where i live! i'm probably gonna try it out and see if it's an at home problem or an all around problem! i wonder could it be my router at home!
