My Alu iMac has one annoying problem in that it won't automatically reconnect to my WiFi router when I either first boot it or wake from sleep. My old iMac G5 on 10.4.10 did this every time, as does my PowerBook. Having read the Apple Discussion forums I'm not alone with this. It's possible that the problem is in the driver for the Santa Rosa chipset being used on this model, but I have been wondering whether there is a setting I've pulled over whilst importing my data that perhaps is having an effect. Firstly, does this sound reasonable or not? Secondly, if it does sound plausible has anybody tried installing the 10.4.10 Combo updater from the Apple website to see whether it sorts the issue? If so, what were the results? (BTW, sorry for starting this in the OSX forum, but it occurred to me that if the SR chipset is the cause some MBP owners might be having the same issue).
