The wifi router is located in ROOM A, connected via Ethernet cable to a PC. I require wireless access in ROOM B, which is 20 meters away from ROOM A and separated by two walls. Would it be feasible to simply modify the router by replacing the short Ethernet connection with a longer cable to the antenna on the circuit board and positioning the antenna in ROOM B? (Referenced in the second image). If this is possible, please advise whether you can use Ethernet cables or recommend a suitable low-resistance wire. My consideration is that long wires may affect performance due to increased resistance. Ethernet cables typically have around 18.8 ohms of resistance, which rises with length. The router's antenna connector also has limited current flow.
For alternative solutions, consider Powerline Adapters. Pairing two provides a cost between $18 and $35.
Consider placing the router in room B and connecting the Ethernet cable from room A to the PC. Alternatively, you could install a second router in room B for better coverage.
Find an affordable Wi-Fi hotspot and connect a cable to it. Consider using a more budget-friendly router or another access point.
