Ok, this one has me stumped. A "public" wifi spot. Cannot connect with either mine or my wife's Macbooks running Lion. Can connect with no trouble at all with either iPod Touch 4G and iPad2. This hotspot incorporates its own screen that pops up when you connect asking you to agree to their terms. This pops up immediately in IOS Safari but never shows on the Macbooks using either Safari (which fails to open at all) and Chrome which just never loads the initial agreement page. I tried turning off "Enable phishing and malware protection" in Chrome but that didn't help. What am I doing wrong here?
