I have HG255s hawawei router which is connected to the ISP as follow:
The HG255s router -> hard(solid) ethernet cable -> an ethernet port in the wall -> hard(solid) ethernet cable in the wall -> media converter -> Fibre cable -> the ISP.
Now the router is in another room and the walls block the wifi signals , so i bought another soft(stranded) 30m ethernet CAT-5 cable. When i tried to connect the stranded cable to the internet port in the hawawei router, it didnt work.
Like this: Hawawei router -> soft(stranded) ethernet cable -> ethernet port in the wall -> hard(solid) ethernet cable in the wall -> media converter -> Fibre cable -> the ISP.
But when i connect it like this it worked: My pc -> tplink router -> stranded ethernet cable -> hawawei router -> hard ethernet -> the wall -> solid conductir ethernet cable in the wall -> media converter -> fiber cable -> ISP.
So my question is, why didnt it work when i connect the stranded etherent directly from the wall to the hawawei router ? . It seems like the stranded ethernet doesn't work with the internet port but works with the lan port. Thanks for reading.
solid ethernet cable = hard ethernet cable | stranded ethernet cable = soft ethernet cable
