A non-directional antenna means by design the antenna itself does not have a direction, otherwise described as more or less transmit/receive gain/power in one direction, by itself. This sounds weird.a non directional antenna being directional.but this is how it works. A non-directional antenna will broadcast and receive in the direction of its ground plane. I'll preface this with a little antenna explainer on what you're seeing. It all depends on your setup.įor more information on antennas, I recommend these sources: A USB extension cable might fix any number of these issues, or make them worse. The antenna's lack of 'room to breathe', proximity to it's 'ground', proximity to a noise source (the computer) and an imperfect 'ground' or 'counter-poise' or 'symmetric half of a dipole' are probably all reasons why there might be reception issues. Sorta like a symmetric and orchestrated tug of war with a solid rope.įor your USB dongle? The computer case is probably the ground, or the opposite side of a dipole, however you want to look at it. Dipole antennas are balanced antennas and use the opposite symmetric half of itself as a 'counter weight'. For unbalanced antennas like monopoles, this would be our planet (hence those 'unbalanced' antennas NEED a ground to operate). This is why antennas in 'free space' have different radiation patterns than the exact same antenna a couple feet off the ground!Īkin to tug of war on rollerskates, antennas too need some 'mass' to exercise their equal and opposite electromagnetic force on. This can even happen if the conductive materials aren't between the transmit antenna and the receiver, sorta like holding a piece of paper behind your head and somehow not being able to scream as loud! This happens because antennas create an electromagnetic field all around them! And this near field is altered by conductive materials as well as the ground plane. Similarly, conductive materials inside the 'near field' of an antenna can cause excessive distortion of this field thus altering the radiation pattern and signal strength in the 'far' field. If you hold a piece of paper in front of your face while screaming, a far away listener won't hear you while a nearby listener can still hear through erratic and seemingly random paths the sound waves take. I am far from an expert on radios, but from what I understand:Īntennas create EM fields that propagate outward.

It seems that on Windows, one way to solve the problem is to change the power profile, but I'm not sure how to do this on Linux, if you even can.Antennas are a highly complex subject and it can be very hard to know what's going on with a particular setup. * Whether the computer is mostly idle or under heavy load, I still encounter the problem.

* I do have a Bluetooth adapter right next to it, but this problem still happens even if there are no BT devices connected.

The PC that the keyboard/mouse are connected to is wired. Even if my idle phone is the only device connected, I still get this problem. * My router supports both 2.4GHz and 5GHz bands, but most of my devices are only connected to 5GHz. * Batteries for both are relatively new one is over 70%, the other is 90%. * I've swapped USB ports and even swapped the Unifying Receiver. * They are roughly 2m away from the receiver and almost have line of sight, where maybe my knee might get in the way. Here's what I can tell you and what I've tried: Since the issue is seemingly random and only affects one device at a time, I think I can rule out that the USB port or receiver are defective. I will experience one of the devices disconnecting maybe once per hour on average, though the keyboard seems more prone to disconnecting. I've been having issues where sometimes, one of the devices will loose connection for a few seconds, and re-connect.

I have a wireless keyboard and mouse by Logitech, connected to the same Unifying Receiver.
