I seem to be having issues with wifi on ICS. A little history, I loaded ICS from home and everything had been working fine. Brought the device into work with me and connected to the wifi. Made a single connection that worked fine. Went to show a co-worker how it worked with moboot, and rebooted back into ICS. From that point on, I can see the listings of AP's that were in the system already, but WIFI doesn't fully startup. I tried setting my thunderbolt to a wifi router, it never saw the new AP. (Confirmed the thunderbolt was working as my co-worker's iphone was able to see and connect to it)
I saw mention in another thread of su'ing and running "rm -rf /data/misc/wifi && reboot". I tried that with wifi disabled, and another reboot, but I get "rm failed for -rf, Read-only file system".
Any thoughts?

Update, I just went out to the /data/misc/wifi directory and started rm'ing the files under it that way. I've been able to reconnect to wifi now!

This fix seems to work well for me:
Find the WiFi spot that you want to connect to. Click Forget then toggle Airplane mode. Turn off Airplane mode, turn on WiFi and then try to connect to the hotspot you want. You will have to enter the credentials again, but it should connect.
It seems that the cache gets corrupted, and while I've seen success clearing cache, the Forget and airplane toggle seems to work just fine (at least I don't have to keep rebooting). I'm still looking into what the exact trigger is that corrupts the cache, but it seems that I have to do this every time I change WiFi spots.

Thanks for the info. I am am new to CM9 and was having the wifi not connecting issue after a reboot and was about to give up for now. This is the only thing that has worked for me, except a complete reinstall. Again thanks.

Until today I could not connect to my home network without forgetting it and reconnecting, and my uni's network has been almost completely unusable (on CM9, whereas webOS has been great).
Attempts to manually change locale/region in various ways have all failed.
adding "ap_scan=2" to data/misc/wifi/wpa_supplicant.conf fixed the problem with my home router. Hoping it will work at uni as well.
If you have wifi trouble, if nothing else can help, and if you're bored, maybe you can set ap_scan mode to 2. This mode seems to be appreciated by some of the more frustrating/crappy drivers out there. If it works, let us know! Good luck

I do like 'coonhound'. If I boot to WebOS for the first time that day, then WIFI will work when I boot to CM9.

WOW! Thanks "Proik Islam" I'm running CM7.3.5 and have been struggling with Wifi not reconnecting for a month!
Your fix below really seems to have solved it for me!
Question: Why isn't this fix either... A) Posted elsewhere as a WIFI FIX or...
Added to CM releases so it's not an issue in the first place!

The ap_scan=2 option improved the situation although I have to enter the wifi settings once the device has booted.
But at least it's reliably connecting to the access point now.
