one would really only affect the other if android were running within webos for example
Here is what I did most recently that worked: booted into WebOS and turned OFF wifi in there. Went back to Android and wifi now works correctly. I have shut down and booted up several times since and the wifi has been working. Is this a real solution? I don't know. It may be a coincidence. But I am wondering if the WebOS wifi settings have any effect on our CM9 wifi...I admit I know very little about all this, so someone here may have an answer.
in the meantime, if you're having wifi trouble, you may want to try this method.
