I'm not sure if I'm posting in the right subforum, if I'm not, please let me know. Hey everyone, I´m having problems with my brand new macbook(MAC OS X 10.6.1). First thing is: I have a wireless router(linksys wrt54g), and it works well with my windows based notebook. But when I try to access the Internet with the Macbook, I'm able to connect with the router, but with no internet connection (in the airport icon there's a "!" sign). What should I do? The Macbook also doesn't connect when I plug it to directly to the ethernet cable. Second thing is: I use another wireless signal I found near my home, but sometimes I'm connected to the network, with total signal strenght, nothing says I don't have an internet connection, but the safari or firefox simply doesn't access any websites, nor does any other softwares. What could be happening? Hope someone can help me out with this one, thanks.
