I used a crummy AT&T (*coughAT&Tsymbollookslikedeathstarcough*) router to build a private LAN. It has no service/DSL connections, there for it detects no internet access (naturally) and will give me this pop-up on a Mac:
This, as you can see, seems to be a Safari window of sorts that is sourcing captive.apple.com. Because I have no DSL connection, all DNS resolutions get translated to the router's web host. This means that every 5 to 10 minutes I get this pop-up. The WiFi connection does work, but I get this annoying pop-up that interrupts my work.
On an iPhone, I have a similarish problem, although it is more consequential. In Settings --> Wireless it gives me this same page asking me to Log In. I assume that's the function of captive.apple.com. I know places like McDonalds or Starbucks will do this to make sure you come in and buy something before getting on their WiFi.
My Question is this: How do I disable this on a Mac so that I don't have to worry with this pop-up anymore? The iPhone is a secondary problem, but it would be nice to have a solution for it. Would a /etc/hosts entry fix it, or is it more complicated than that?
