Can't keep it on WIFI

It works great in bluetooth mode but it will NOT stay on my network and when we join the GGMM network it plays music for 10 seconds, drops the network, then my phone will go back to my last known good connection which is my own network. I know how to set up the network as I'm a IT networking technician so it's not my set up. No instructions on how to solve this issue unless I just can't find it.
