Hi.
A couple of months ago I bought a new Samsung mobile phone and 2 new tablets.
After a week I had to send the mobile phone back because it lost wifi. After a week I got it back without them finding anything wrong.
I had the same problem with my tablets.
Checked the internet for someone who had similar problems and then found that this was quite common.
Have been in contact with Samsung and they are also aware of this.
I have 50+ devices connected to wifi and only these 3 lose the wifi connection. Also have other Samsung models that this problem does not exist.
Have tried the stuff suggested on other forums.

I have X60 x3 units so there is no problem with the signal strength

What can I do? Is there a software update that can fix this?
