so i was with verizon when i downloaded the lollipop update and everything went smoothly. back in may, the 5.0.1 update rolled out and i downloaded it also. as soon as i did that, my wi-fi is horrible. i have to be in the room of my house that holds my router in order to get wi-fi signal. this causes me to burn through data like crazy. back in august, i switched my phone over to straight talk to save some money. i was told that another update came out after i switched for verizon customers. there have been no updates with straight talk yet. is there a way i can force this update or anything else i can do to get my wi-fi working the way it used to?
