Especially in a moisture country like sea land.

Near the power button is WiFi antenna connector in my version is copper direct touch like the NFC not like ifixit and the touch place is oxidize very much.
Tear N7100 down, burnish it to shining and everything goes wonderful.
It just need a small "+" driver.

Finally I fix the n7100 weak WiFi problem.
Fix the problem also fix some battery drain due to bad WiFi signal casued device enhanced WiFi power to connection.

Also the left and right top is mobile antenna. burnish it to shining also get a better signal and power save.

Excellent result for me.

I tear down my n7100 completely.
Clean everywhere with eau de cologne and ear stick.
Then mod the wifi cooper wire and stick with cyanoacrylate near power button space.

As a result wifi signal bar goes up 1 to 3 stage.

This actually worked! I was quite frustrated with the low wifi signal(1 bars), but now it increased upto 3 bars
