Apple issues Wi-Fi update v1.0 for Lion iMac users

updated 11:45 am EST, Sun February 26, 2012

Helps iMac reconnect to networks after sleeping

Apple has issued an update over the weekend specifically for iMacs (late 2009 and newer) entitled Wi-Fi Update v1.0 that is said to correct an issue where the unit does not automatically re-connect to a known Wi-Fi network after waking from sleep. The update requires that users be running the latest version of Lion (10.7.3) and weighs in at 25.81MB. It's available for all supported OS X languages.

The update differs from the EFI update for iMacs and other models issued on Thursday, which was numbered v1.9. That firmware update dealt with issues regarding boot device selection when a USB device was hot-plugged, as well as resolving an issue that could prevent HDCP authentication after a reboot.

The Wi-Fi Update v1.0 is recommended for all Lion-running iMac users. It will appear in Software Update on qualifying machines, or can be downloaded directly from the company's support website.

    iMac have a lot of Wi-Fi issues

    Will this update fix the packet loss and abnormal latency as well?

    Oh, so now..

    They admit there is a f*****g problem. This has been a problem for me since updating, called Apple Care 4 times a bunch of procedures to no avail.

    There was well over 100 pages of complaints and potential solutions on Apple/discussions, have both never seen or experienced anything like it for so long.

    Same here...

    I had the EXACT same problem constantly with my 11-inch MacBook Air 2010 model. The issue is very widespread indeed. It's nagging issues like these that really try you patience!
