Q: Broadband Connection Problem.

I am in the U.K. My ISP is BT and I have a HomeHub4 with BT Infinity.

Suddenly my MacBook Air will not connect to my Hub4 router. The message is "Wi-Fi 2 (my HomeHub) does not have an IP address and cannot connect to the Internet."

My iPhone 6 Plus connects with no problems so I have temporarily connected my MacBook to the internet using my iPhone as a personal hotspot and it works well. Even my Devolo Homeplugs connect easily.

I have rebooted my router and my MacBook and checked in Network Preferences but I still cannot directly connect my MBA to my HomeHub.

Any ideas?

MacBook Air, OS X Yosemite (10.10.3)

Good day Julian,

If you are having an issue with connecting to your home Wi-Fi network with your MacBook Air, I would suggest that you troubleshoot using the steps in this article - About Wireless Diagnostics.

Thanks for using Apple Support Communities.

Safe computing.

Oddly enough I switched my Mac off yesterday morning about 08:30. I switched it back on about 18:30 and my connection to my router was magically restored!

However, I will definitely read the article you have highlighted above. Thank you!
