Internet access via WIFI connection

I have an issue with a Sprint TP2 with WIFI. I'm able to connect the router but not able to access the internet. If I connect my phone to the laptop I can use the internet if I change the (Connections:connections: network management) from Sprint to My Work Network but I'm not able to connect via WIFI. I have (Connections: wifi:configure network adapters) to WORK or THE INTERNET for Broadcom 802.11 DHD Network Adapter but it doesn't help. Under Connections: tasks:MY WORK NETWORK:Set up my proxy server I check the box next to THIS NETWORK CONNECTS TO THE INTERNET but it won't stay checked. The profile for the router has been deleted and recreated with no success. I've tried other WIFI routers with no success. My touch pro has no issues. BTW: I'm using version WM6.5.
