There are various tools available for this purpose. I currently use a Wifi analyzer (though I haven't used it recently). Also, placing a high-frequency antenna at the end of such a lengthy cable isn't recommended; you'll encounter signal losses due to the cable's quality. The cable must be of excellent condition for optimal performance. A cable that is too long compared to the wavelength—like a 1-meter wire for a 5GHz signal, which spans only a few centimeters—is problematic.
Your setup involves a modem with both 2.4 GHz and 5 GHz bands, and you're noticing performance differences depending on which band you use. You've already tried resetting the modem, but it hasn't fully resolved the issue. To improve your connection, consider placing an antenna further away from your computer and nearer to the modem. This should help strengthen the 5 GHz signal. If you'd like more options, you might explore using a Wi-Fi extender or checking for interference in your area.
Your performance has dropped slightly (cause unknown), yet online gaming still feels smooth. Besides that, your latency appears to have noticeably improved, suggesting less delay should be expected. First, connect your PC directly to the modem via a patch cable to verify internet speed. Testing on Wi-Fi isn’t ideal—obtain consistent measurements for speed and latency at the modem. This helps determine if the issue lies with your connection or your network setup. If both are stable, focus on troubleshooting the Wi-Fi setup. Ensure you’re using 5GHz when possible. Use an app like Wifi Analyzer (available for Windows 10) to measure signal strength in dBm. Values above -50 indicate strong coverage; otherwise, a different antenna might help. Remember, an external antenna only benefits if it’s much nearer the access point or better positioned. The impact of distance diminishes with longer cables—though placing the antenna strategically can still matter. If placement isn’t ideal (e.g., behind walls), adjusting settings on both devices may be necessary. If signal strength remains weak (-65 or lower), consider relocating the antenna. If you’re stuck, tweaking AP and PC configurations might resolve the problem. Ultimately, for stationary setups, a wired connection is usually preferable, though it’s not always feasible.
In reality, attempting to capture a signal from behind a large metal enclosure (such as your PC) typically results in more significant loss compared to using a cable.
I face significant and regular lag spikes, though otherwise latency remains low. There are currently two walls separating my PC from the modem (across a corner), so I'm considering routing it through another room via a vent for better access. Alternatively, running it outside the door would eliminate wall interference. Unfortunately, I don't own the property and I question whether the landlord would approve drilling through walls.
It seems the decision hinges on where the equipment is positioned. Based on the details provided, the antenna might work well: just make sure you check the signal strength first before purchasing.
You should assess the signal strength without the antenna using a tool such as a Wi-Fi analyzer. This helps see if adding an antenna would improve performance.
