reply to TSI Keith

Re: [Cable] Modem will only connect to Internet directly to PC..

I have tried both of these suggestions. I have cloned the MAC address on the router, but as stated, the modem signal will not even go through a simple unmanaged switch

I have logged into the modem, as instructed by support, and reset the defaults, same result. I do not understand why this would not even go through a simple switch...

Thanks for the response, I can't believe that a direct connection works fine, but two different switches, and two different wireless routers, both different brands, and one brand new, will not pass the signal...

skinnydoggy, the problem you are having is either very strange, or it is the standard MAC address, DHCP, connected computers limit that TSI Keith is mentioning.

The steps TSI Keith outlines do fix this issue, but small deviations from the steps could cause the problem to continue. If you understand the reason it happens, that might help you to avoid it.. To that end, do you understand the issue with MAC addresses, Rogers DHCP server, and why clone MAC solves it?

I have cloned the MAC address of my PC in the router.

No, I don't understand.

I assume that teksavvy has my MAC in the Rogers DHCP server, and Rogers is sending me new IP's every so often. Is it possible my MAC is duplicated or something? My setup has not changed, and it had been working for a year, until about a week ago. It came back intermittently, off and on, and now it will not come back up at all. Nothing has changed.

The issue seems VERY strange. It must be something on Teksavvy's side. work from home fairly often, and can't afford this downtime.

Thanks for the response. teksavvy has not responded in the Direct forum, and you seem like a very valuable member in this community.

Teksavvy doesn't have anything to do with your modem getting online, or IP assignments on your account. All they see is a bunch of traffic from thousands of customers on a POI. Teksavvy does give Rogers bundles of IP addresses for specific neighbourhoods to use. That's all Teksavvy does, everything else is Rogers.

At some point I'll type up the entire sync process, but for now I don't have time... What you need to do:

Disconnect your cable modem from the coax cable. This stops information about what's connected to the modem from getting to Rogers. It also starts a countdown for Rogers to clear all cached information about your connected devices.

Pick a router that you think is most likely to work. Connect it to the modem and power and factory reset it (get rid of any MAC cloning you may have done in the past). Modem is still not connected to coax.

Reboot everything, just to be sure. Modem is still not connected to coax.

Access 192.168.100.1, and you should get the modem config page. This is through the router, and the coax is still disconnected. (Problems? Access the status page of the router. Does it show a 192.168.100.x IP address for the WAN or Internet interface?)

Do the factory reset in the modem (sounds like you have a SB612X, and you need to do "Restore All Defaults" on the Configuration page). Modem is still not connected to coax.

Reboot everything again. Modem is still not connected to coax.

At this point you can attach the coax and wait for sync lights. Once the modem is fully synced you may have to reboot the router again.
If that doesn't work, do it all again except don't reconnect the coax for 30 minutes.
