At a public WiFi where I have not had this issue before (but last time was two months ago). WiFi connection symptoms seem like the access point/router is not communicating with the outside world. BUT it is a little unusual:
- Macbook, iPad, and iPhone all connect to the SSID. But none of them can access internet at one end of the building and the iPad works fine at the other end. Nowhere in the building can the Mac even ping the router.
- Typing this on a library Windows 7 box. I shut this box and the Macbook down, and moved the Cat-5 cable from their box to the Macbook. Booted and tried different methods (ping/telnet to DNS/whois/others) and no connection.
- Sounds like Macbook is seriously screwed, but I can use the iPhone "personal hotspot" through USB or through WiFi with the only issue being that the cell service around here is intermittent.
Any troubleshooting ideas? Is this a duplicate of Network OK but no Internet connection. Can this be faulty hardware? ?
Update: "Related" sidebar shows that many people have similar problems, though none of those showed up in the "suggestions" when I was typing the question.
