Since upgrading to Tiger, everytime my powerbook goes to sleep, it diconnects the airport link, so everytime it wakes up I have to login to my airport network - most annoying.
i wonder if it has to do with the router. when i was at my gf's house my PB did the same thing once i installed tiger on it. she had an SMC router. at work/school this happens only sometimes. i dont know what wireless system is used. at my apt my roommate has a D-link router and that works about half the time. so i dont know, im curious also if anyone has a fix though.
