Hello, I have a Galaxy S3. A few weeks ago, my wifi randomly stopped working. It finds wifi networks quickly, but after entering the wifi password, instead of connecting, it will go to "saved, secured". If I try connecting several times, occasionally it will give an authentication error, but then go back to "saved, secured" after the next try. I've tried everything I could find on this forum and elsewhere online to fix it and so far nothing has worked... - Rebooting - Turning flight mode on and off - Forgetting network and entering password again - Changing various network settings - Different wifi networks (tried on at least 20 as I'm currently traveling), including an open one. - Two different sim cards, no sim card - Various factory resets - Wipe cache - Apps that supposedly fix your wifi From what I've read, the factory reset not working likely means it's the hardware. I know very little about how phones work in the background but if my phone finds the networks without any trouble, is it really likely to be a hardware issue? Is there anything else I could possibly try? There's no personal data on the phone anymore so I'm not concerned about losing data. And frankly it's a bit of a brick without wifi so not worried about anything else either really. I'm in rural Vietnam at the moment so taking it to a shop to get fixed isn't an option. I do have a Mac with me that I can connect it to if necessary. I'd appreciate any ideas that might help fix this. Thanks in advance!
