    does speed between modem and router matter?

    Bit of a difficult one to explain but basically If I use powerline adapters between my router and a device I lose lots of speed. Mainly due to old wiring I think. I was wondering if I was to move the router and use the powerline adapters to connect the modem to the router instead of router to device would I still lose speed or does 'the speed' between the modem and router not matter like it does between router and device. Hope you can make sense of that

    I haven't got any powerline adapters at the minute to test it hence the question

    Why wouldn't it matter, given that the main purpose of your network is I presume to deliver the internet, so why would you want to slow down your internet at the first hurdle? It matters more than between the router and your device, that's just slowing down one device, slow down the modem to the router and you're slowing down the internet for every device.

    That's what I'm asking.... Would I still lose speed if I was so use the powerline adapters to connect my modem to my router rather than my router to my device.

    Judging by your edit I'm guessing it does then. I just wasn't sure if the data transfer rate between the modem and router worked in the same as router to device

    Powerline adapters are transparent except for a few features so pretty much act in the same way as an ethernet cable. There's some lag but nowhere near WIFI. Depending on how fast your internet connection is will be an important factor, you should be able to hit around 50mbit with any issues. Over this then your performance will suffer.

    I'm curious to what issues you are having as powerline adapter positioning can sometimes yield massive improvements in speed.

    Normally I get 15mbps when wired when I used powerline adapters between router and device speed drops to between 2-3mbps. However I live in an old 18th century pub and feel it's probably to do with the very old wiring and think maybe the electricity isn't all on just one circuit. (Would the powerline adapters work at all if they were on separate circuits?)

    ​Yeah older wiring can cause issue but I'm surprised about the amount lost. You're probably right about the cause of the loss. I'm surprised about the amount of loss though. WIFI would be a step up from this though. Are you running the adapters direct from the wall ?

    Ye direct into the wall. Wifi is just as bad due to the thickness of the stone walls. Had many problems using repeaters and access points too

    ​Any other options of running ethernet ?

    I'm actually already using a 50ft Ethernet between the modem (downstairs) and router ( upstairs) but if I can find a way to manage with out this I can then use it to connect router to downstairs pc which is next to modem

    Ethernet is always the best solution I've found. Lots of ways of wiring ethernet cable though through buildings. Most people don't realise that it the same method to get a network cable ran between levels as an aerial cable.

    Ye think I'll have to run another Ethernet or maybe even the cable that goes from phone socket to modem then I can move modem upstairs and use existing Ethernet to connect downstairs pc to router. Thanks anyway

    I wouldn't move the modem from the master socket as this just drops internet speed. I would connect the two with switches.

    Normally on your network the modem/router is only used for internet/DHCP server and firewall. Your local network is normally connected through your switch as it gives better performance as it has less overhead than a router.
    You can add other switches or WIFI access points off the main switch which is a good way of doing this.
