My tablet has all of a sudden gone offline and can’t reconnect to WIFI. The wifi swipe button just stays grey and it isn’t reading any wifi addresses. All other phones and tablets work so the Internet is fine the problem is the device. Have tried restarting, rebooting, etc. Please help!
I have this same problem. I bought the tablet used wiped the OS and the cache partition. WiFi and Bluetooth still grayed out and auto switches to the off position after a few seconds. I would think using safe mode, and a wipe that this is not a software issue. I have been reading and there are a lot of other users who have this problem. I have seen some people mention that they reflowed or soldered. This is risky for obvious reasons. If any one has a diagram or a chip set map I can pull the mobo and see if there is a bad solder joint. I have seen repairs done before with epoxies and would be willing to try to repair so we can put up a guide. I think it’s pretty lousy of samsung to put out a product and have so many come up defective after weeks or a few months of use.
