I have MacBook Pro 2014 with latest High Sierra 10.13.5.
Month ago I've replaced my SSD to Samsung Evo 960 with Sintech adapter. When I boot recovery to install Mac OS I tried to connect to my home wifi but it didn't connected. Then I connected to 5 ghz wifi. Mac connected and I forgot about it.
But some days ago I've tried to connect to 2.4 ghz wifi and it didn't connect. I again tried to play at home with 2.4 ghz and found that signal is weak (NetSpot). Mostly it don't connect (write that password is wrong. But if disable password - simply don't connect). It connecting time-to-time, work a bit and then Internet disappears.
I started think about SSD, so I replaced it back to original and all works fine!
So the question is.. What might be wrong? I read something about kapton tape. But first of all I don't understand what to isolate. Secondary I didn't found it in stores. Maybe I can use something another instead of kapton tape?
