Assuming you have BIS and have already set up your BBM, it sounds like it's just a glitch. I would recommend deleting your Wi-Fi profile in your phone, resetting your wireless router and adding the home Wi-Fi profile once again. While you're at it, it never hurts to do a battery pull for good measure; remove your battery while your phone is powered on then replace it.
However, if you don't have BIS in place and you're trying to set up your BBM over Wi-Fi then HSingh2012's reply would apply.
