It's a hassle but you need a tech to investigate the low signal level.


Called Comcast and they said -11 was within range and as long as I did not ahave an internet or tv issues they did not see a reason to come out. With that said...my splitter is in my office and I split the coax going to my cable modem so I can also make a run to my tv in my office. You mention a bi-directional splitter...are you referring to an active or powered splitter? THe splitter I have is not powered and is a Regal 5-1000 Mhz 2 way splitter.

This is what I am talking about.

I'm not recommending this one, just using it as an example.

If this is what you have

it is a bi-directional splitter with a 25 db return loss.

All interior cable(s) should be RG6 quad shielded. Lesser grade cable(s) noticeably degraded my internet and TV performance.
Modem should be connected to splitter 3.5 (out)leg; Regal 2-way splitter has two 3.5 (out)legs.
RG6 source example which has never let me down including 100ft runs http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10216

Well...went out last week and purchased an amplifier and now everything is running smooth!! FInally!! Just when I lost all hope. Never was a problem with Ooma but with the signal through our cable line from within the house. Went to 'Shack and got an amplifier and now everything is within parameters. No dropped calls, no weird lights on Ooma..everything is working fine. Thanks to everyone on this forum in helping me out. Took awhile...but we got 'er done! Thanks everyone!

Here is the link to the amplifier I got at Radio Shack...

Thanks for sharing your cable amplifier solution and positive experience with everyone. Can you please add RS amplifier link for other users? :D
