I personally really love Lion, but issues with wifi are getting me completely tired. I hoped 10.7.3 will change things but it seems to be even worse🙁 Now, often my iMac does not connect after sleep (it says its connected but opening any page last several minutes - only turning airport off and on helps), sometimes after sleep/restart says that no preferred wifi is reachable but when I open list of available networks, mine own network is listed and after choosing it no password is needed to join (and if I do check system preferences, my networked is set to be preferred) and sometimes, wifi signal dies for few seconds (randomly) - I am getting so tired by this, cmon Apple, don't be redmondish, do something with these issues!
