Splitter Chooses One or the Other

Question

Hello! Sorry in advance if I use the wrong lingo. Hopefully everything makes sense! So my family recently decided to expand dvr/cable onto our second floor where we have a nice new TV. We have DVR downstairs and got a box on the second floor that allows us to access that DVR. Everything works well and good with the only cord coming out of the box besides the power cord being the coax cable that comes from the wall. However, while the Wi-Fi works in some rooms on the second floor, others it goes at a snails pace if it even works at all. To solve this, we got a wireless extender from verizon and, when plugged straight into the coax cable that comes from the wall the improvement is tremendous. We get about 50 mbps download speed in rooms we only got 10 before. Needless to say, we want to have the network extended working on the second floor. However, when using the provided splitter in order to access cable/dvr capabilities and the wireless extender, the splitter only works on one or the other. That is, when we plug the coax cable from the wall into the IN port on the splitter, if we plug a coax cord from cable box into the splitter before the extender, we get cable and dvr/guide features but no extended wireless, and if we plug the extender in before the box we get the extended internet signal but no dvr/guide features on the cable.  This is really frustrating because at present we would have to abandon the splitter and switch coax plugs everytime we want to use internet in one of the hard to reach rooms and hope no one wants to use the DVR/cable at the same time. For some more information, our splitter is a MoCA 2.0 2-way splitter (PDI-2wwb-2.0/5-1675 Mhz) and our wireless extender is an actiontec WCB3000N.  In summary, we are using a splitter currently on our second floor to allow a 2nd verizon cable box and a wireless extender to operate simultaneously, but at present when they are both connected only one or the other is connected to the network. I am assuming this may be a problem with our splitter, but from what I've read it sounds like the one we have (named above) should be bidrectional. Can anyone please help? Thank you! 

Answer 1

Hi and thanks a lot for your message! I went through the box system information like you suggested, and the pictures below are a sample of what came up when I tried your methods. I did end up powering off router, extender, stb and turning on as you suggested with no luck (even after waiting a loooooong time before plugging the next one in!) Below is what came up when I plugged straight from wall coax to box (first picture), from coax wall to splitter to cable box, with extender coax also plugged into splitter and turned on after the cable box (second picture), and if the extender is plugged in first, then the cable box (third picture). Hopefully these photos shed some light on the situation. What's important to note is that I followed every step of your instructions in terms of plugging the coaxes in one-by-one. However, despite refreshing everytime, the screen generally looked like picture 1, with minor variations in the TxRate (plus one or two occassionally) aka there didn't seem to be much difference between the connections. The only significant change I noticed upon plugging the extender in was the EMM data became False, but I am not sure what that even means. Also, after extender was plugged in first and the stb second, it wouldn't even allow me to access the system information Info screen because of no data connectivity. It would just show the small box (picture 3) and ask if I wanted to troubleshoot connectivity issues. (troubleshooting was no help)   Please let me know if these pictures can help make sense of this! Thanks!
