Powerline adapter question.

Hey all, the jcomm guy claims that normal powerline adapters like tp link wont work with their modem, i think he is just trying to upsell their own wifi extender. Anyone got some experience with this, would appreciate the advice.

  1. As long as the powerline adapter is plugged into the LAN port of the home-gateway/router, it should work. It’s not doing the ISP credentials or anything special. Just extending the LAN port connection, so to speak.
    You will need a router that can do the credentials for the ISP. Most likely they are referring to this, if the service comes with a home gateway/router.
    (The modem may be an all-in-one where the modem and router are together. This is typically called a home-gateway device. I forgot what the CaTV setups are like. Been awhile since I used it.)

    Just remember you can’t connect the powerline adapter to a power strip or anything. Both plugs need to be in the wall outlet. Otherwise the speeds are either really really bad or won’t work. I couldn’t find 1 gbps ones in Japan at the time. Ended up ordering off of US amazon.

    This is from my experience, what you’re using and such may differ. Hopefully it’s useful. Let me know if you have any other questions and I can try to help.

  2. I had to use Ethernet-over-power when we were renting. WiFi couldn’t penetrate the walls, for you see the steel was much too strong.

    The network connection worked ok, but the bandwidth was a bit crap. It was ok for work email, web, etc. But downloading gigabytes took fucking hours. Only use if there’s no other solution.

  3. Use a mesh system and connect it to your computer using the ethernet cable.

    I used PoweLines before and my internet had really bad speeds.

  4. Mesh is the way. Still not as good as direct WiFi to modem and never anywhere near direct cable connection, but good enough.

  5. I tried using power line adapters once and they were extremely slow. I gave up on them. We live in a fairly large two-story house, so I bought a Netgear Orbi mesh system. The main Orbi router is downstairs with an Orbi satellite upstairs and we have a full strength wi-fi signal throughout the house.
