Thank you for your comments. I do have direct TV and only use Cox for internet. I was not aware that the modem should be on the primary feed, but that makes sense! I checked the line coming in and this is what i see.
The primary is hooked up to a two way splitter both are 3.5 DB output. I traced one output of that splitter to be the coax terminal wall outlet of the new location where i moved the modem. The other output of the splitter then goes to a 3 way splitter (3.5 db, 7db, 7db) only two of which are used. I traced the 3.5db output of the second splitter to the original coax terminal - at the previous location the signal was going through at least two splitters. One of the 7db outputs is hooked up, it must go to another room in the house.
It looks like the primary feed is not long enough to eliminate the use of the first splitter. i am going to check behind the wall outlet now.
Thanks again
I reads like you only need 3 splits: Primary Outlet, "New Location" Outlet and wherever the second split goes on the 3-way splitter.
Assuming the 3-way splitter is good (3 Mbps), I'd just replace the 2-way splitter with the 3-way splitter.
The "New Location" outlet is getting a good signal because it's only going through 1 splitter. All other outlets seem to be weak.
If you need/want a new splitter, I'll assume Cox recommends 1000 MHz (1 GHz). Also, only get the number of outputs you needs. The more ports on a splitter, the less signal it passes to each port. Unused ports would still weaken the signal.
Your Internet modem should be on a 3.5 dB outlet.
