some sites blocked on specific wifi
My macbook air safari is blocking my access to some sites on a specific wifi server. The same sites are not blocked on my same macbook air on another (close) wifi server. I did check that with another phone I had none of those issues on the wifi server where I have the problem. Called the internet provider and he checked all was ok. He told me that it was an Apple issue and to look for a solution?
Thanks
MacBook Air, OS X Mavericks (10.9.5), SAFARI 7.1.2
