Murphy - so far this suggestion has worked to stop my Ooma from endlessly cycling from on to off. I am curious as to exactly what MAC cloning has to do w the Ooma. My understanding from Linksys was that MAC cloning enablement was recommended as part of the setup for the router. Hope you have time to explain. Have been working on this problem for the last 2 weeks. Ooma support was worthless.
P.S. Can't thank you enough as I was unable to rely on Ooma for it's intended purpose.
Then routers became popular and the "brilliant" router designers gave the router the ability to use the computer's MAC address (spoof) to fake out the cable company. Meanwhile the cable companies switched to using the cable modem's MAC address to handle authorization. Apparently this change is unknown to the router designers. There is no good reason for a modern router to need to be able to spoof a MAC address. Ooma, in their infinite wisdom, comes along and makes MAC spoofing automatic instead of an off by default option.
Ooma could save themselves a lot of grief if they deleted spoofing from the box entirely. There is no need for it at all
Cable modem's memorize the first MAC address to register following power on. They will ignore requests from any other MAC address. This is how the cable company prevents you from grabbing more than one IP address from them unless you are paying for more than one.
Ooma connects to the cable modem using it's built in MAC address. Sometime later a computer connected to the Ooma tries to access the internet and the Ooma automatic firmware says "Hey I better use the computer's MAC address" and changes it's traffic to the modem to use the computer's MAC address. The modem ignores the Ooma box from that point on.
An update - the Oooma is still cycling on/off despite turning off MAC cloning. Hate to be a bother but do you have any other ideas. This is driving me crazy! TIA
