Hi Ahmad,
I was just confused, it is on a scale of 1-100…you are right!
Please check SSDESUL, and if it is set to high values such as -75 dBm try to bring it to -85 or -90 dBm. Please try this in steps and not as one shot in order not to affect the network.
You should check as well QDESUL, it should have a value of 20-30 dtqu depending on you how much clean is your frequency plan.
Good Luck
