I just buy this phone and I discover that my phone have conectivity problems.
When I try to connect to wireless access point the phone reject to connect. If I restart the router it can connect.
It is not a router trouble because I can connect with many devices.
I read more people with this problem.
Do you know how can I fix it?
Thanks a lot.

I would like to includo more information:
The router is updated and the problem continue.
I this problem occurs in other routers and obviously I can not modify the firmware in all the routers that I want in order to fix this problem, when all the other devices can connect without problems.
The router use protocol 802.11b/g, I fixed as only G but the problem persist.
There is no MAC address filtering active.
I tried dinamic and static IP.
Security, tried with WEP and WPA-PSK, I can not modify this for compatibity questions with othe devices.
Thanks a lot 
Try downloading Wifistatic from the Market then restart the router then tap on the application and hit add configuration.
