Wireless Keyboard - Input Lagging

[MarcoMeswara]

[SOLVED ]
UPDATE ]

Guys, got a 1.5m USB Extender Cable and made sure the receiver was about 30cm / line of sight of the keyboard.
Note earlier the usb receiver was at the front of the PC under the table. Now its on top of the table ( near the monitor ) in sight of the keyboard.

First day - problems seems 100% SOLVED.

Thanks everybody.

Update - This fix seems to have solved 95% of the lagging issues. On 2 occasions, I had to switch of /off the keyboard to get it input accepted.
But overall the modprobe.d solution was great - words / characters are no longer lost etc.

Note - Created a file in /etc/modprobe.d/ directory ‘20-usb_stop_autosuspend.conf’ and added …

options usbcore autosuspend=-1

And then save/reboot.

Now check autosuspend value:

cat   /sys/module/usbcore/parameters/autosuspend

It should display -1
