Mac forgets home wifi network every time

Each time my powerbook sleeps, or restarts, I have to reselect my wifi network. It's my home network, and although I have "Ask to Join New Networks" selected in Prefs, ... my network is not new.


In Advanced, my home wifi network is at the top of the list of preferred networks.


It's a nuisance having to selected manually every time I start my computer. What's the problem??

iMac, Mac OS X (10.7.2)

I found a way easier way to fix this annoying problem! Go into network preferences, click the "advanced" button on the bottom and find YOUR wifi. Just click and drag it to the top of the list of wifi addresses, and PRESTO! MY wifi is what I get immediately signed in on, not one of my neighbors. Yippee!!

I changed my router wireless security encryption setting and issue was solved, been a week and no connection drop, even after wake from sleep my iMac mid 2011 was able to instantly connect to WIFI. The encryption setting on my router are Automatic(Recommended), TKIP, AES. By default it sit on Automatic(Recommended), I changed to TKIP, rebooted the router and have never seen a drop for the past week. Hope this helps some of you out there~ Cheers~

So I was looking for an answer to this and kind of figured out a solution. I am using a work supplied computer that has been corpified, but we have multiple guest networks that I use for testing software since the corp network treats everything as hostile and does not allow me to do my job.


Select System Preferences > Network > Advanced


Select the WiFi tab (if not already selected)


Click and drag the network you want to use as default to the top of the list and [OK] out of everything.


I performed a couple of reboots and put the system asleep multiple times and I am still connecting to my preferred network.
