Before resorting to JP1, you may want to try a few troubleshooting steps to see if you can get your remote working better. Some things you can try include:

Resetting the remote and trying to learn the codes again.
Checking the batteries in the remote to make sure they're fresh and properly installed.

Moving closer to the device you're trying to control to see if that improves the signal.

Checking the device itself to make sure there aren't any issues with the IR receiver.

If none of these steps help, then JP1 may be a good solution. Just keep in mind that it can be a bit complicated to set up, so you'll need to be comfortable with technology and willing to invest some time and effort to get it working properly.
