my phone did the 6.1.1 update since then wifi not connecting. i have tried reset wifi, wipe partition, turn phone on and off, last resort factory reset. i have taken to repairs to find out why this has happened. they were not able to do diagnostic test to check if its software issue yet after they checked with repair guy they came back with needs a new screen. so my question is can i use a Ethernet cable to do diagnostic test will that work? is it best to try independent repair company? the cost obviously is more than half the cost of the phone which is a lot or just cut my losses. feeling at a lost if there's is anything else i can do or at least a realistic repair price?
