    Okay, I am going to buy the recommended powered splitter and put it in the new outside cable box. I am going to plug the basement coax cable into the "out 1/power in" port. Inside the basement, I will attach the power inserter into the coax wall port. From the power inserter, I will connect a coax cable to the ac adapter and plug it into a power outlet. I will also plug the new WCB6200Q into the RF out port and connect the mini to the WCB router. Sound right?

    Attached is my drawing.

    1.What splitter should I put in the Attic? Should it be the existing powered one? We are going to add a mini to one of the 2nd floor bedrooms. Should I not cable the 2nd floor bedroom that doesn't currently have a device, or can I just terminate it at the wall or splitter?
    2. How do I confirm whether the device already in the outside cable box is a POE filter (see attached photo) and if it is, should I remove it when I connect the new powered splitter?
    3. Is the 2way splitter that I put in the office last night the correct kind? (See attached photo.)
    4. The recommended Actiontec WCB6200Q device is $150. Is that the best option for basement wifi combined with the mini?

    -Any markings on that connector you think may be a POE filter?

    -The splitter in your office is the correct one.


    I do have concerns about your network setup. Especially the number of splitters between the cable modem and the cableco as well as potential interference from having MoCa on the same system.

    I'll take a closer look to see if I can find markings later this afternoon.
    As I understood it, I can't move the modem to the basement without the expensive mesh solution? Actually, why can't I put the modem in the basement instead of the office with this new config I am doing?
    My thought is that I could always return the Actiontec device and move to something else/mesh if this solution doesn't fix my issues.

    You can put the modem/router in the basement, but it may mean that you don't get good wifi on upper floors. In such a situation you'd probably want a wireless access point connected via MoCa on the upper floors. I think it probably makes more sense to keep the Cable modem and router where they are, since I assume that your wifi needs in the basement will be less demanding and you can get away with an 802.11n access point.

    just wanted to give an update: I don't understand it, but in the last two days I am suddenly able to see my 2.4 and 5ghz networks in the basement. I'm getting speeds of 35 to 60 Mbps down there. I have made no changes except for connecting my office mini directly to the router via Ethernet and replacing the office 3 Port splitter with a MoCA 2 port splitter. of course this happened after I ordered the access point which should get here today. I am seeing no need for it now though. I am still going to call Comcast out about the numbers on the cable modem. I am getting -6.92 to -9.9dBmV downstream power and 47 to 49dBmV upstream power. We are also having streaming issues with Amazon on the main floor mini.

    Thank you all so much for your deep analysis of my environment. You really helped me to understand things better. I'll post an update when there is something further.

    Comcast says that they have remotely tested the connection into the house and that I need to call support for my cable modem myself since I own it. I'm going to try to do this myself. Can you tell me why the amped splitter that you are recommending is better than the one that is in my attic? I'm assuming that I would put an amped splitter in my outside cable box and then replace the attic amped splitter with a regular MoCa splitter?

    Every splitter reduces your signal level. 3 ports are kinda worse, as they're basically two 2 ports stacked together.

    By putting the Unity Gain Amp at the input to your system (in the box outside), you're preserving max signal level. By further eliminating unnecessary splitters, you'll maintain a high signal level.

    You can log in to your modem to see your signal levels.

    Move the modem to check levels at different outlet locations in the house.

    If the levels are good, then your problem isn't with Comcast.

    Don't you also have 'unused' wires to the box outside? That (maybe) run to the basement? That could be utilized to eliminate more splits?

    I didn't mention them, but there are two wires that go outside that we don't have plugged in. I don't know where they go. I think they go to basement rooms, but haven't verified that. You may have seen them in a picture. Attached is a current picture.

    1. Comcast provided us with an XG2v2-P device that we plugged in to a spare bedroom on Friday. The next morning, the TiVo minis couldn't find the master. This has happened sporadically before, but not with all minis at once. We were able to reconnect them, but they couldn't find any apps. We disconnected the Comcast device, unplugged the power, moca, and ethernet connections to the minis and ran some errands. When we got back, we plugged everything back in and the minis were working again. I don't know if the Comcast device caused the issue or not. It is not currently plugged in, but if we can use it in that room we would like to. I don't know if that is a proper configuration to have a Comcast device in a separate room. It is not a DVR.
    2. We anticipate buying a mini for the second bedroom. Currently nothing is plugged into that drop.
    3. On the Bolt and on the minis the "what to watch" section doesn't work most of the time. Occasionally, it will for a bit after a reboot.
    4. The main floor mini has problems showing Amazon shows. They freeze and stutter.
    5. At home alone, sitting in the office next to the router on wifi with no tv on and not doing heavy workloads on my laptop, sometimes I will get 8Mbps download speeds and other times 40Mbps download speeds.
    6. I don't know if there is a p o e filter in place. there is something that looks like it in the outside box, but 20191209_105407.jpg 20191111_104412.jpg there are no markings on it anywhere.

    I can provide any updated numbers, I just need to know exactly what would help.

    Thank you for your help.

    You're going to get very poor MoCA throughput through the input port of the Unity Gain Amp.

    I'm surprised you're getting any at all...

    What do you recommend I do to improve it? Move the commscope splitter outside and put a regular splitter in the attic? I don't have a cable running from outside to every coax drop in the house. It sounds like that is what you are saying would be best??

    Yes.

    And discover the other ends of the unused outside wires.

    Ok. I will order a MoCa splitter for the attic and see if I can figure out where the other 2 wires go.

    The other thing is: start documenting your current signal levels.

    What signal levels does your Modem report with the current configuration?

    What MoCA Levels are reported by your TiVo devices right now?

    I thought you were ordering the MoCA specific Unity Gain Amp posted up-thread?

    In the ideal configuration, you only want one splitter with <= 3.5db signal loss on the leg that goes to your modem between the cable from the pole to your cable modem. In addition, it is preferable to have that connection (from pole to your cable modem) isolated from your MoCa network via a POE filter.

    Realistically, you want the absolute minimum amount of splitters between the pole outside and the devices inside.

    Every splitter you use for convenience degrades the signal to the device intended.

    Yes, that is what I am going to do because my current amp splitter doesn't have the power inserter with it.

    KP, you said:
    "that Commscope Amp ought to work, the better MoCA Amp is the CSMAPDU5VPI.

    Commscope CSMAPDU9VPI 9-port HomeConnect Passive VoIP Amplifier with MoCA(NEW) 689719680866 | eBay"

    I currently have the 5VPI. I think you intended to recommend the 9VPI. As far as I can see, these two devices are identical except for more ports on the latter. I will order the one with more ports that comes with the power inserter and replace the attic and with non-powered splitter. Unless your intention was that I also leave the existing powered amp in the Attic?

    I will record the levels again today.

    No.

    Those Unity Gain Amps won't pass MoCA very well through the Input Port.

    Optimally, having every room connected at the Amp would allow for minimal signal drop. You'll just have to see what happens.

    I chased the cables this morning. There are 5 cables in the outside box. Two aren't connected and I now know that they go to two other basement rooms. The three that are connected go one to each floor. So, cables outside:
    -3 go to basement rooms, 2 of these are not connected outside currently.
    -One goes to the main level.
    -The final cable goes to the attic, which then gets split and supports everything on the second floor, including the cable modem, the router/wifi, the Bolt, a business VoIP phone, an Ooma phone, currently one mini (soon-to-be two minis) and possibly a Comcast box.

    I guess you are telling me that it would be better if I could get more wires to go from outside directly to the coax outlets on the second floor. The ideal would be if I had 2 direct cable drops into the office: one to the cable modem and one for the MoCA? (Do people actually have that setup?) Then, both of those devices would be connected to the router?

    FYI, this house currently has 3 cable outlets in the basement, 1 cable outlet on the main level, and 5 cable outlets on the second floor.
