Hi All, I've searched this issue, but nothing has worked. Network Diagnostics was "unable to fix the issue", as well. Basically, my wireless network shows up in Airport on both my iMac and my Macbook. Full bars. But the internet doesn't work. Never connects. I have reset and restarted the Netgear router repeatedly. It seems to be working perfectly. The DSL modem is from Comcast. Has anyone run into this issue and been able to solve? I'm sure its something simple that I'm missing. Thank you.
