Issues, solutions proving inconsistent
New installations of OS X Lion are causing Wi-Fi connections to fail, according to posts on Apple's support forums. Affected users say that despite perfectly functional Wi-Fi before the Lion upgrade, they are suddenly seeing connections become intermittent or broken. Other devices will continue to hold a link, such as iPads or Macs without Lion.
The complaints add, though, to those from people who say they have had unstable connections since Snow Leopard. Solutions proposed by users can vary widely. While some propose ideas as simple as deleting a Keychain password for a network, others suggest everything from reconfiguring DHCP settings to trashing the SystemConfiguration folder under Preferences, or even doing a fresh Lion install. A temporary remedy involves just switching to an Ethernet connection, if possible.
While the Lion rollout has proven smoother than some OS launches, it has not been without some trouble. Reported glitches have affected the likes of NAS drives or even the installation process itself.
