Device functioning similarly to a Wi-Fi antenna
I'm searching for a gadget that mimics an antenna to capture Wi-Fi signals and send them via Ethernet cable. The setup should place the device 5 meters away from your PC using CAT 6 cables. While I understand CAT 6 is ideal for your current router-to-PC connection, it's not practical here. You're also interested in a power solution that can be supplied through Ethernet PoE, so it won't rely on a nearby outlet.
Two options exist: a USB extension cord linked to a WiFi antenna or purchasing an affordable TP-Link router. This device can handle connections from various Wi-Fi sources and transmit them over Ethernet.
You can find a lengthy USB connection – it includes an amplifier that boosts signals, allowing distances beyond the usual 3 meters. Variations in power usage for Wi-Fi can affect voltage levels along the cable; for instance, you might receive only 4.5V instead of the expected 5V, which could trigger a reset or shutdown of the wireless USB device. To mitigate this issue, consider using a boost regulator to raise the voltage from 3 to 5 volts for your wireless adapter. A longer active USB cable is available here: https://www.amazon.com/AmazonBasics-Acti...B01L81WQ2O. Alternatively, you can purchase a step-up converter on eBay at the link provided, which adjusts voltage from 3 to 5 volts. For a compact solution, use a short USB extension and remove the insulation, then connect the regulator between the red (+5V) and black (ground) terminals.
Many WiFi repeaters can switch into a mode called WiFi bridge, capturing a wireless signal and delivering a wired Ethernet link from there. You could experiment with a different Netgear model referenced in the image, tailored to your home's Wi-Fi strength and coverage.
As @kirashi mentioned, several WiFi repeaters are capable of this. My computer has been linked in this way for over five years now. Meanwhile, the extender can also serve as a Wi-Fi source in the attic.
Yes, but these devices need electricity to function. He mentions there isn't a power source close by. Using power over Ethernet could be costly. You'd need a PoE injector to supply power through the Ethernet cable, and then a compatible device at the other end. If he prefers not to run mains cables outside the room, the simplest and most affordable option is a single USB active cable, like the one I provided. This cable provides both power and data. The main concern is voltage loss over distance. Long cables can cause significant drops, especially with higher currents. For example, with 10 meters of cable and typical resistances, the drop can become noticeable. Assuming standard AWG24 wires, a 20-meter run would result in about 1.7 ohms total resistance. Using the formula V = I × R, at 100mA this drops to roughly 0.17 volts, still within normal limits. However, higher power usage increases the drop. The product description warns that bus-powered devices needing full USB current may need a powered hub to maintain voltage. This is necessary because the actual voltage can fall below safe levels. A solution is to use a step-up converter, which raises the voltage before it reaches the device.
I understand, I'm open to suggestions. Could you share some examples of devices you're considering?
