I could connect the Motorola Xoom tablet to my Belkin router and wifi works fine. Then around the time Froyo came out, Xoom cannot obtain ip address from my Belkin route.
I have changed all the security settings in my router and rooted all devices, but Xoom just says "scanning" then "Obtaining IP address of my router" and then disconnects.
Try the following steps for fixing the issue
1. Make sure you have no settings from prior to Froyo.
2. Restore your router to default and try again
3. Clear cache on the tablet.
