Question WiFi not turning on

[Super777man]

Checked around the internet and this problem seemed to be quite common.
WiFi could not be switched on. See the YouTube link below at 1:20mins.

Question: has anybody tried to Odin reflash it to the same/latest firmware. No rooting or anything fancy, just reflash the same firmware.

I had this issue after updating to the latest firmware but I don’t think the issue happened right after updating. Probably a few days later. I was hoping if this could fix the issue.
Thanks.

Update.
I tried it myself via Odin updates to the latest/same firmware for my region.
Problem not fixed. Same thing. WiFi still doesn't turn on.

Same situation here. Wifi not turning on.
it was working while phone was in folded mode.
As soon as open, wifi won't work. Then phone goes to restarting.
Did factory reset and no help.
Came here hoping to reflash old stock firmware to see if it will work, but you have answered above.
I read on some of forum and one guy sent in to Samsung and they changed screen and it is working like a new one.
Maybe some to do with wifi antenna built in to the screen or something?!
Coincidentally I have the person installed a new screen protection and that person didn't know well and rubbed hell out of screen. That was about a few days before my wifi went out.
????
What do you think? Maybe relate it, or not?

P.S. I have less hair on my head now and not cause of being old (66).

updated today to 5.1 and I got the same issue. looking at the history of this problem it seems to me that samsung are not aware of it because after almost a month they still released the 5.1 firmware.

This looks like a hardware problem to me. Something inside is disturbing the WiFi radio when you unfold the phone.
