As shown in the 1st picture, the wifi router is in ROOM A, connected with a pc by Ethernet Cable.
But I need wireless connectivity in ROOM B 20m away from ROOM A separated by 2 walls.
Can I just open up the router and replace the short wire with a long cable to the antenna from the circuit board and place the antenna in room B ? (shown in the 2nd picture)
If it's possible , tell me if I can use wires from ethernet cables. or suggest me good cable with low resistance.
My thoughts : maybe it won't work due to the resistance of long wire. ethernet cables have 18.8 ohm resistance which will increase with length. Even router's antenna connector has lower electric flow.
