@Riley_S Thanks for the reply Riley! You have no idea how much headache you have saved me! The magic work was Access point. I cant believe I was an IT hardware/software tech since the beginning of PC...

I recently had 2 TL-WA850 extenders wired together 3 floors apart in my place in Spain which worked great for about a year then I lost connectivity in my rooftop workshop. I messed around with them...
