Re: $40 dollar charge for them putting a splitter on a cable? The splitter will help with the power levels. I have no cable service except internet through Cox (had Suddenlink before Cox). My power levels for downstream were in the upper end of the +10 limit. The upstream was a little low. I have a two way splitter installed that brought by downstream levels close to 0 and boosted my upstream a little. So since you say you have problems with power levels then a splitter might be the best solution to help get the power levels in better range. They lower down stream power levels and raise upstream. If the downstream levels are to low then you might need a amp installed to boost the levels.
Without a inside wire maintenance plan if Suddenlink still has one. You are responsible for anything that goes inside the home after initial install. Outside they take care of from the pole to the house for free. With a DOCSIS 3 modem your downstream power levels should be between -10 to +10 the closer to 0 the better.
If that's the case the splitter should have been installed in the box and not the customers responsibility.
