On the Android Google cell phones, you can download an APP called WiFi Analyser. Perhaps iPhones have a similar APP available? Now you can see a display of all the WiFi traffic around you. With this choose the least busy channel.

The next advice is to put the device on your LAN that does the WiFi in a clear space and high up in your premises. This gives you all the chance you have of getting a better signal. Now do the same for your JBL box within reason.

Go into the Settings of the Android and turn on the Bluetooth. Select "find Devices" (The device needs to be 'on' also)

Should not be a problem. If you download the quick start guide from this site and follow the pairing instructions for your Bluetooth phone that should work well.

If you do not have instructions for Samsung Illusion then you can follow page 83 for pairing bluetooth in the manual from this site.

Either pair it through Bluetooth pairing, or use NFC (near field communications) if both devices have it.

All this is detailed in the instructions.

Put JBL Charge in pairing mode: turn on Charge. Hold down power button till it flashes red and blue. You're in pairing mode. Go to your device and find Charge and pair up. Done!

This indicates that the Blue tooth pairing with the already paired device has been reset and the JBL Flip is ready for pairing with new device. This position, red and blue blinking, can be obtained by long pressing the power buton.
