It does not mean that you have to change channel. It indicates that you had 9% ocupation at the moment of the test. In fact you should run the test several times to get a clear picture of channel ocupation before chosing your channel. Normally you choose the channel with the least ocupation, but 9% is nothing, I've seen channel ocupations of 60% 70% and even 100% and then you know about it because you don't have a wireless signal.
What you are actually looking for is excessive interference on the channels that you are using. For instance, interference of 3% on channel 3, 10% on channel 4, 60% on channel 5, and 0% on channel 6, 60% on channel 7, 10% on channel 8, and 3% on channel 9 would meand that channel 6 is functioning properly if you are using the default channels of 1,6,and 11. If you saw channel 6 with more than 5-10% interference then you know you have either co-channel interference or a device effecting your AP on channel 6. Because of the 22mhz channel width in 2.4ghz spectrum you can only use these 3 non overlapping channels. 10-15% interference on a channel can be detrimental and cause excessive packet retries. Remember, you only have to worry about 1,6,11 being clean.
It is confusing. You say "10-15% interference on a channel can be detrimental and cause excessive packet retries".
But rhobab say it is normal. It is normal to hit at a higher percent.
If i am using channel 6 for my AP. My interference is 20% on channel 4, 50% on channel 5, 7% on channel 6, 30% on channel 7. Does it means that channel 6 is not between 10-15% and so it is consider normal and less co-channel interference?
