Help: CM600 No Internet Connection??
Hi everyone.
Hope someone might be able to chime in with some suggestions and help me out.
Have Xfinity Internet and should be getting 250Mbit for speed.
I'm getting a good 85-93ish ma...
power levels are ok.
for no internet on your iMAC -->
1. If you change from airport extreme to iMAC with an ethernet cable, Please make sure to reboot the modem
2. Also, I think your iMAC may not been configured with DHCP mode causing this issue. Please check this. If you think, it is good, then provide output of "ifconfig" command from terminal app on iMac
for speed issue> check the speed of direct connection
if still open, This is most likely wrong bootfile issue. Please call comcast and ask them to send correct 250 Mbps bootfile.
1. Yes, I have rebooted, reset, cycled down the modem.
Nothing seems to work.
Only time modem works is when it is connected to router.
How do I check speed of direct connection?
2. How should the iMac be configuered with DHCP mode? I just checked only I don't know what I should be looking at.
Here is the output of the ifconfig:

the IP on your MAC BOOK seems wrong. It may be staticaly assinged to 10.0.0.x subnet.
see this to change the configuration to DHCP
