Us and the neighbors have been sharing an internet wifi connection through their router/modem one floor up from our apartment which has been working out ok. Streaming video works (just). However, the wifi connectivity has been really bad except for one spot in our living room and the wifi repeaters we installed caused so much lag or bandwidth loss that they were unusable.
One solution I instantly thought of was to draw an ethernet cable from the router/modem to our floor below. But this would require physical breakup of their floor and our ceiling, or tampering with the lines already in place through the walls (don't feel comfortable with that), in order to get the cable through.
There is, however, already an extension of the same telephone cable that connects to their router/modem that we can connect to on our floor. See pics:
This is where the phone line is connected to our neighbors' router.:
This is where that same line ends up on our floor:
Our apartments used to be part of the same house, that's why. I've been looking for ways in which I can tap this line and I found two technologies that either work over the TV line (moca) or the electrical lines but not over the phone line. The neighbors and us have separate power service panels with our own fuses so running it over the power lines would probably not work. Is there anything like these technologies that will allow us to get connected through their modem over this phone line?
Otherwise, the only option I see left is to get a more expensive subscription at the provider that offers internet over the TV coax line. Then we share that one with the neighbors through a moca box since the coax line also runs to both our floors.
