I just bought my 12" PB (my first mac!) a week ago. However, I have not been able to connect to the internet AT ALL. This is what I posted on macosx.com, and have also explained to the AOL, Apple, and Linksys tech support people (gah!!!): I just bought my 12" PowerBook (with Airport Extreme wireless card, using "Tiger" OS X) about a week ago. Ever since I brought it home, I have not been able to access the Internet at all. At home, I have a cable line connected to a Linksys WRT54G router, to which one desktop computer (PC) is connected to by wire. My PB (as well as my previous laptop) are the only wireless computers on the network. At first, I thought that maybe something was wrong with either the router, the computer, or our ISP (AOL). After calling all three (who blamed each other), I got nowhere, although the Linksys tech support gave me extra DNS server numbers - which did nothing but aggravate the process. After doing more research, I found that many people have had the same problem with accessing the Internet on the WRT54G router. I have heard many ways to try and fix the process and have tried some, but have not been able to do it correctly (I still cannot access the Internet or sign on to AOL). Here are the settings on the router and the Airport Extreme wireless card as of right now: Linksys WRT54G router: Connection type: DHCP (Automatic Config.) - *Note: I have heard that AOL uses PPPoE for this setting instead, but upon using this setting, the PC desktop computer that is wired to the router would not sign on to AOL. Wireless - network mode - mixed all default security - WPA Pre-Shared Key, TKIP MAC filter enabled (have entered Airport MAC ID) UPnP - enabled (heard this worked, too, but don't know exactly what it does) Airport Extreme wireless card: - is connected to our home network, with the WPA key enabled - AOL for Mac OS X says that to enable this connection to work, a TCP/IP connection must be established and then modified to include the cable modem. however, upon signing on, AOL cannot seem to recoginze or connect to the TCP/IP connection. If anyone can shed some light as to how this should work, and what I need to change, it would be appreciated. --------------------------------------------------- I looked this up on the 'net, and I see that a lot of people have this problem. What gives?
