I have a cable 'net connection and just purchased a wired/wireless router so that I could lounge around the house and go online with my new iBook. The router is made by SMC and it is a "Barricade G" router... The model number is SMC2804WBR. I set up the router and have my 2 PC's wired to it and there is an internet connection on both PC's and I can share files between them just fine. So I installed my Airport Extreme Card into my iBook G4. It seems to be installed properly. The icon shows up in the top bar, and under my system info it shows that there's an airport card. I called up the router's tech support, they told me to call Apple. I called Apple, they told me to call the manufacturer's of the router. (the Apple tech support I called said that the Airport Extreme card seemed to be installed properly) Anyway, nothing I've tried has worked as far as getting any signal on the iBook, even when I have it right next to the router. Note that this is without ANY encryption. I tried for hours to get it to work with and without WEP or WPA encryption. Nothing has worked. I have tried manually entering in the SSID under network name and everything. It will either go through and do nothing (That's what happens when I have no encryption set, and use no password on the mac), or it will say "Error connecting to network "network name here." I updated the router's firmware and everything, but still have the same results. Anyway, I have tried pretty much everything I can think of but I can't seem to get it to work. I'm a newbie to networking in general (and admittedly it took me awhile to get the WIRED part of my network working properly -- I needed to unplug the router/modem and plug them back in.) I'm sure I'm missing something simple and I just hope that someone here will be able to show me what I'm overlooking... There's gotta be some setting in my router or my Mac that will make this work! If anyone needs any info or screenshots from my router config page, let me know! Thanks alot!
