Switched ISP rcn to comcast unable to connect to internet
hardwired ethernet connection worked when connected to RCN (5+ years), but just switched to COMCAST and having problems w/modem. modem resets after 2-5 minutes online, and continues to reset until i disconnect the ethernet plug from mac.
With the help of COMCAST (over 15+ hrs on site & 4 days, 6 techs on 1st name basis and they are starting asked what's for dinner):
replace ethernet cable, replaced modem, COMCAST ran new lines to house & inside, ran new phone line to modem (landline connected to modem goes dead also), reset the modem, unplugged modem, today the tech tried a seperate modems-one for the phones and 2nd for internet,
In "Network" Location: automatic, Show: Built-in Ethernet, Selected: TCP/IP, Configure: using DHCP.
When all modem lights were lit i ran a diagnostic and all lights were green, after 2-5 minutes the ISP, internet & server turned red.
Same things happen when I try setting up router (netgear), but put that on the back burner for now. just trying to get one up at a time.
i am able to connect to the internet hardwired to a pc as long as i am not connected to the mac.
And finaly my question(s). Anyone out there having the same issues? How can I fix it? I noticed blinking cusor on TCP/IP network screen "DHCP Client ID", tech says don't need to fill in. Is this correct?
One of the techs will be back tomorrow and hope to have a solution. He is bring a 3rd modem, but not sure this will solve the problem. I seem to think there is a setting that needs to be turned on/off. or some other really simple step I am missing.
