I have a Droid X where when I try to use the WIFI one of two things happens either a the network crashes out completly or B the phone restarts. Any ideas?
What do you mean by "network crashes out completly"?
As for the phone restarting, I've never run into that problem myself.
Try doing a soft reset on the device by powering the device off, removing the battery about 30 seconds, and then powering the device back on.
Once the device is powered back on, review the new applications and delete applications or widgets that use the wifi feature, as such applications may conflict with the feature.
If the problem persists a factory reset maybe needed.
