Help Nexus one Wifi problem.

[atn_chargers]

My Nexus one will only pick up my wifi when it is rebooted. Every time after when I shut Wifi off and then turn it back on, I can't get it to work. It is connected and speedtest confirms that the data is working, but other than that I can't load wepages, ect. HELP???!!! All of my other devices don't have this problem so I'm assuming that its just my Nexus one that's having issues.
