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!
