htc3600 can't connect to my wifi router

[komple]

Hi,
i have strange problem with my htc 3600 and siemens wifi dsl router se568. My ppc connects to router but i can't ping router or access internet or any other computer on network. Strange thing is that my ppc connects to other wireless networks without problems. I tried 2-3 laptops and they connect to siemens router. Also i tried some other pocket pcs and they connect also to my siemens router. only combination that doesn't work is my htc 3600 and router.
Anyone has any suggestion how to solve it?
One more thing i use WPA-PSK TKIP encryption.

Ok found solution. For some strange reason when I put wifi preferences fon pda Best Performance it connects and works fine. When i return it to Best Battery it will not connect. Strange. Probably it is something with my wifi router.
