Hi, after smugly claiming that the airport problems had all gone after updating to 10.5.2, they seem to have just come back However, they have only come back immediately after i did a time machine backup (i only do them once a week or so) - and now i think about it, the dropout returned last week immediately after i did a time machine backup then. Coincidence? I thought i fixed the dropout last week by changing from WEP128 to WPA-PSK. But now i'm wondering whether time machine is somehow messing up my settings etc? anyone else find their airport starts dropping immediately after a time machine backup?
