I have my cable modem -- Telo -- my computer. All ethernet cables. No routers or wireless stuff. Nothing can be simpler than this. Telo worked for one month and then stopped working on 2/2. Don't know what the problem is. Ticket # CS29660. Every time I call they keep asking me the same questions over and over again. Changed ethernet cables (actually using ooma's cable). I can connect to the internet using my cable modem (thats how I am typing this topic).
I hate to write bad reviews about people, but hey I paid $200 for this device and it worked for only 1 month. A phone IS important to me. If it doesn't work I have every reason to be mad.

Hopefully someone will be able to help me out.
