Hi Everyone.  for some reason the post i had up has disappeared, i am unsure why.

I am having trouble with my powerline system. i previously had this specific setup working with an older adapter set, but one of them must have broken while we were decorating so i got some new ones. 

when first installed, they worked fine but then stopped working.  oddly they allow some traffic through.  i installed the utility, for the good it did me, and it said that the network had good speed, and that there were no issues.  i can also ping and trace to other locations on the network (both wired and wireless).  the (virgin media) router is detecting my PC upstairs as being connected via ethernet (over powerline).  

i can ping, and ping from, the PC that is powerline connected, and that machine can ping and TR outside the home network (test locations abroad etc all work fine).  but no web access is granted using any browser. everything works fine if i am connected via WiFi from upstairs (i want powerline as the wifi can be flaky sometimes) but as soon as the ethernet adapter is enabled/plugged in, i completely lose connection (although i can still ping/TR outside the network).  i cannot access the routers utility if the ethernet/powerline is connected (connects via browser).  everything works fine if the PC is connected directly to the router without powerline (i moved it downstairs to check).

oddly, if only the wifi is on, and i start a MS Teams meeting, then enable the powerlien connection, the video quality gets better, and continues to work if the wifi is disabled.  however, if i then stop the meeting and attempt to restart, it says i have no connection (but can still ping/TR the other person).

any ideas, im a little stumped.
