Sorry guys, posting the thread did it... I found the problem by comparing my laptop settings with my desktop, maybe someone else can be helped:
Under Wireless Network Connection/Properties/TCP/IP Settings/Properties/General/Advanced: the Default gateway was set to 192.168.0.1 (was Ok for my old router, the Linksys one has 192.168.1.1.). I removed that entry and it works!!
Thanks for the attention!
