I have (another) weird problem on my mac.
I have a wireless bridge at home, which works ok with my phone and other computers. But on my mac, it behaves in a weird way. I can connect to it, but I cannot use it with any browser. I can ping Google successfully but I cannot access the same website on the browser. If I try to connect to it through a vpn (as I am doing now) then all works ok.
In addition, I only get problems at night as in the morning it works fine (probably this is due to traffic, but it might also related to the fact that my wife is using the bridge already, although as I said I have no problem with the other devices).
