Help me with accessing internet (wifi problem)

[hanjh0529]

Im using 2013 mid mac pro retina. Here is the situation. Since few days ago, I can connect wifi but cannot access internet (safari, chrome) all of sudden. I watched youtube and googling to find the way to fix it. Delete all wifi and creat again, rename it, make inactive, PRAM reset. Nothing works so far.

Desktop and iphone both use same wifi and access internet without an issue. And strangely, except for my house wifi, this stupid laptop can connect cafe, library and school wifi and internet as well.

What should I do? Do i need to reinstall OS? or update version? Any adivce comment please.
