Wireless keyboard misses out or repeats letters

Windows 10 Home

USB cable keyboard works okay

But wireless keyboard (Logotech K400+ or a Victsing touchpad keyboard) either miss out or repeat letters (iiiii etc.).

I have tried all kinds of setting changes following google searches on this problem (but not really sure what I am doing, or what correct settings should be, just followed the advice) both in keyboard settings (Windows 10 Control Panel) and in the Ease of Access (also advanced part).

Still happens with both wireless keyboards - no matter what I do - but USB keyboard works fine!

I’m stumped!

(both keyboards are plug&play with the little USB plugin receiver and I don't know if they also work with a special driver or not = and if so where do I find the driver = thought about removing it and trying to reinstall = but this might not be the issue at all?? I simply have no idea what is wrong = but seems strange that the USB works okay = which makes me think it must be something to do with the wireless rather than the keyboard settings, but???)

Glad of help, and thanks

Thanks sml156

I have the software installed, and the battery is full (new keyboard). The receiver is only a very short distance away from the keyboard so that is not the problem either.

still baffled

Try putting the tiny USB receiver on a USB extension cable. I have mine placed under the monitor only 2 feet from the wireless mouse & keyboard. Also try removing then reinstalling the Logitech drivers. Note the driver tells you the battery health and estimates how many days battery life is left.

Thanks Steve C and sml156

have now put the receiver on a USB extension, will see how that goes
