band - defines default set of data rates when using this channel.

width - channel width in MHz, allowing to specify fractional MHz part, e.g.

frequency - channel center frequency in MHz, allowing to specify fractional MHz part, e.g.

list - name of list this channel is part of.

If name is not specified when adding channel, it will be automatically generated from channel frequency and width

name - name by which this channel can be referred to.

This menu contains ordered list of user-defined channels that can be grouped by means of list property.

center frequency range: 4800MHz-6100MHz with step 0.5MHz (500KHz), width range: 2.5MHz-30MHz width step 0.5MHz (500KHz) ДЄdvanced Channels are configured in interface wireless channels menu.

center frequency range: 2200MHz-2500MHz with step 0.5MHz (500KHz), width range: 2.5MHz-30MHz width step 0.5MHz (500KHz).

Non standard center frequency and width channels can only be used with interfaces that support it.Д¬urrently only Atheros AR92xx based chips support non-standard center frequencies and widths with the following ranges:

non-standard channel widths (specified with KHz granularity) for hardware that allows that.

non-standard channel center frequencies (specified with KHz granularity) for hardware that allows that.

scan-list that covers multiple bands and channel widths.

I know it's a general reply but it should get you going.Advanced Channels feature provides extended opportunities in wireless interface configuration: If, on the other hand you have guests that frequent your home/office for use of your wireless network but DO NOT have N capable devices you may want to choose 802.11n only (5GHz) - 802.11b/g/n as it provides more compatibility for those non-N capable devices.ДЇinally, regardless of your choice, power is not really an issue here, in other words it won't impact your electrical bill or over burden your solar system.Дoes this help. Oh and the 5GHz is also more able to penetrate barriers that 2.4GHz may not be able to. N radio mode is better because it provides more range. The reason is that cordless phones and other home appliances that are wireless capable tend to generally use the 2.4GHz frequency, hence the 5GHz frequency will yield you better reception. If all the devices in your home/office are N capable you should choose N only 5GHz. In summary choosing Automatic for Radio Mode is fine as long as you verify the actual mode it chose as displayed in the first screen capture. Below is what is available to me in Airport Utility version 5.6 on an Airport Extreme If you hold the alt key while clicking the drop down menu you will get a bunch of choices that you can choose.

N is the most recent and can operate at the 2.4 and 5Ghz frequencies. There are four flavors today, A,B,G, and N. This has always worked better for me than trying to guess at which channel to set manually.Д«ut.I am well aware that some users swear by setting channels manually, so you will have to decide which works best for you.ДЄutomatic Channel selection is fine, what this does is it allows the airport device to analyze its environment, giving it an oppotunity to choose the most appropriate channel as it powers up or restarts. Personally, I prefer to set the router to Automatic to let it scan and select the best available channel to use. If channel 1 works for you, that is fine, but keep in mind that other wireless routers around you are changing their channels to scan and look for a better connection, so while channel 1 may work well today, it may not later today or tomorrow. Regarding the 2.4 GHz band, channels 1, 6 and 11 are the busiest if you have other wireless networks around you, with channel 1 usually being the busiest of all since many routers default to that setting.

If you do, things are as good as they are going to get. Try, 153, 157 or 161 to see if you get the same results. I have it set to channel 149 right now and im not getting very good range(about 15ft away).ДҐ GHz signals are much weaker than 2.4 GHz signals, and they do not penetrate walls, ceilings or any other obstructions well at all, so it will help if you think about 5 GHz as a line-of-sight type connection.
