if i go down and ask them at the twc store for a splitter thats better then the 1 they gave me be4 can they do it?
cuz right now when i got the dta they gave me a small bag in the bag is 3 cables and the cheapo splitter that seems to cause the wierd upload channel problem i have another of those splitters same brand same problems im hoping to save money an have them give me a newer more better splitter if they can but seems all they give out now are those mini cheap splitters ?
You get what they have... If adding a splitter is trashing other devices, you have marginal signals to begin with probably from more splitters upstream.
Is there anything between the outside grounding block and the modem?
Copy and paste the modems level page without the dta/splitter connected.
