I've recently purchased Archer TX3000E AX3000 to work with a Dell wireless keyboard KM7120W. Given that this keyboard allows switching between 3 devices, two of them work over bluetooth 5.0, I've purchased this Wifi Bluetooth adapter hoping that I'd be able to connect to my desktop wirelessly. However, the bluetooth connectivity is so slow, sometimes takes 2 - 3 minutes before it starts recognizing my input from the keyboard. I can say that it's an issue with the adapter and not the keyboard because I also connect wirelessly to my Dell laptop and that's almost instantaneous.
I've updated the drivers, but the issue still persists and at this stage I'm thinking of returning the adapter.
Can someone please let me know if there's a way to fix this.
