I had been having some trouble with wireless networks after updating to 10.6.8. There are numerous posts on the internet about this. I did install the combo update, but my system would still sometimes drop connections for no reason. Tried resetting the SMC, tried deleting all the networks and adding them back. But still the same. Today morning my macbook pro just refused to connect altogether. (Seemed like it finally gave up! :) ). Anyways, after a lot of search and figuring out that it was connected and able to ping servers (Ip) outside the network, I finally deleted the SystemConfiguration file under HD/Library/Preferences (I did take a backup of the folder just in case!). Mac is supposed to rebuild these preferences from scratch if you delete it. And it worked!! Well my mac connected instantly to the internet and has not dropped connection yet. Lets see how it goes. Will post the details in a day or two.
