Discussing the strength of WIFI antena wires and Bluetooth connections.
I'm looking for a longer cable to boost my Bluetooth range, especially for the dual-band WiFi antenas on my motherboard. I'm curious if the signal weakens with cables that are too long—like 10 meters. The product I saw looks promising but I want to know its reliability over such distances.
The shorter 1-meter version would noticeably affect performance compared to antennas mounted on the PC back. I've also tried a 1-meter extension to connect Bluetooth from another room behind a wall. Generally, longer cables result in weaker signals. If you achieve clear line-of-sight with the 1-meter model, it will likely perform better than the 3-meter version. However, if direct line-of-sight isn't possible for the shorter length, the longer one might be more reliable.
I was curious about how dependable a 10-meter cable would be. The one that comes with the motherboard has roughly a 0.5-meter wire, which isn't terrible and does help, though I occasionally lose my connection—usually just once every few hours, enough to make it feel a bit inconsistent. I'm weighing whether to get the 10-meter version or the shorter 2-3 meter one. I don’t know which would be the better value.
Generally, shorter cables perform better. Antennas are usually linked to their devices via coaxial or twinaxial cables, but their lengths remain fairly constrained. Even if someone offers an extremely long cable, it doesn't necessarily mean you should rely on that length. Similar to PCIe risers, signal quality tends to decline with increased distance. Using the analogy, the antenna functions like your graphics card, the PCIe riser acts as the connecting cable from the device to the antenna, and the HDMI cable serves as the wireless connection from the antenna to the connected device. The HDMI cable can transmit a signal over greater distances than a PCIe riser can, regardless of its quality.
Get the best setup by placing the antenna as high as feasible in the room. This reduces interference from obstacles. The same applies to the router—keeping it low minimizes signal blockage from furniture. Try to limit obstructions between the router and the PC antennas. You might not need to swap the antenna unless you slightly adjust the router’s position.
I understand, but adjusting your router for better Bluetooth on your PC doesn't make much sense since your setup isn't causing problems. Your router isn't positioned high, and your PC is using a wired connection, so changes there won't affect performance.
Yeah, sorry, I see a lot of similar comments I often respond to, but this one was really about Bluetooth. With Bluetooth, it's all about having a clear line of sight between your devices and the antenna. Any blockage would likely interrupt the signal since it sends much weaker power than WiFi. Still, keep in mind the cable length—working better is usually a few extra feet through the air rather than just a few more feet inside the cable.
This was the concept, to gently pull the antenna a bit longer and possibly move it from the table to attach it to the door frame when needed. The main question is whether a 10-meter version available would be suitable. A shorter option around 3 meters might also work. I’m still unsure which size to choose—perhaps testing both could help.
Problem is there is no hard and fast rule, we can't really know if they are using good enough cable or if the device you are trying to use is particularly bad at holding onto a signal or not. The only way to know for sure sadly is to try both. There's also the gain on the antenna which for Bluetooth ideally you'd probably want it to be quite high so the antenna is really sensitive on the same level as the antenna, but doesn't beam/receive as much signal above and below where you don't need it.
