Default O2 Xda neo Wifi

I hope someone can help me!

My Xda neo's SDIO WLAN Wireless Adapter doesn't refresh new ip address when i change. I have to reset it when i want to switch connection to Home and office. At first i couldn't find where the problem lies on, only after i installed IPDashboard. Althought the ip in the Wireless Network is changed, the previous one still displayed when i check on IPDashboard. I have to reset it each time to refresh the ip.
