Germany, Amazon, its set to Deutschland.
Nothing changed if i select a other country.
Only european countrys are availible.
I tried it with AirPort Utilitys 6.1 and with AirPort Utilitys 5.6.1
Time Capsule has Firmeware 7.6.1
With Option + Klick i see more transmitter modes (only n, a/b and so on)
but Option + Klick dont bring more channels
My Options are Create Wireless LAN, Security personal wpa2, other ssid name für 5ghz country germany, unvisible network is unchecked, Transmitter mode only n (5GHZ) - b/g/n also tried with only n for both and automatic.
2,4 ghz-channel automatic
5 ghz-channel automatc (this is what i like to change to above 132 because of range extention)
We have seen a number of reports in the past from European users asking about this same issue.
Apparently, Apple limits the use of 5 GHz Channels on European versions of the Time Capsule (and AirPort Extreme and AirPort Express as well) to 36-48 only.
I suggest that you contact Apple Support in your country to ask them whether firmware is available that will allow the use of the higher channels.
Please report on your findings.
Support ticked created they will call me tomorrow. What i dont understand is that they promote the Timecapsule and write on German page, that they support all these channles. also on the US store they wrote
Channels 1-13, 36-64, 100-112, and 132-140 approved for use in Europe
If it is approved why cant i select it. Hmmm lets see what they tell me tomorow. I will write the answers back here.
Regardless of the issue of whether or not you will be able to activate those channels, you should realize that a higher channel number means a higher frequency signal and therefore a shorter range in general (but a higher throughput).
If you want to increase your range without adding a repeater or signal amplfier, you should be shifting to a lower numbered channel, not a higher numbered one.
generally you are right from the frequenc point of view. but der there is a little other effect that is verry interesting in the 802.11n channle 36-48 transmits only with 50% signal strength. all above 100 send with 100%. Thats the reason why you extend the range with above 100 channles. Of cause if there is a other 5GHz Wlan in range they than can overlap and confuse each others.
True enough. On the other hand, If one wants the largest possible range, one should simply set the transmit power to 100% on their current channel. The power must be increased in the higher channels to offset the greater attenuation of the signal - any range increase would be a (usually minimal) happy side-effect.
