On initial Set up my ATC the 5GHz band was on channel 100 on auto, then this has dropped and users. channel 36 - 48 doesn't show anything above 48. My question is, Is there a way of getting back to the higher channel range?
Airport Time Capsule 802.11ac, Version 7.7.9
at the moment it's on at 100 (DFS)
The legal requirement for DFS channels is that they are set automatically. That is what DFS means.. Dynamic Frequency Selection.
UK and Europe (ETSI region) do not allow the range of channels that US has available.
Although it does vary from country to country.
See https://en.wikipedia.org/wiki/List_of_WLAN_channels
US recently changed to allow a huge increase in the number of DFS channels.. the ones Bob has shown are the channels not required to auto reduce. ie can be chosen and fixed. But a whole new lot of channels was opened up by FCC in new regs.. all the channels from 50-144.
It means wifi can run on channels used by weather radar and military radar but must move to a clear channel if a radar begins operation on that freq.
devices operating on 5.250–5.350 GHz and 5.470–5.725 GHz must employ dynamic frequency selection (DFS) and transmit power control (TPC) capabilities
On 10 June 2015, the FCC approved a "new" ruleset for 5 GHz device operation (called the "New Rules"), which adds 160 and 80 MHz channel identifiers, and re-enables previously prohibited DFS channels, in Publication Number 905462.[22]
When/if Apple releases updated firmware for the AirPort Time Capsule, you will be able to manually choose a number of higher channels.
Hi Bob
Tried several different country's but made no difference, However I have put it into auto now and at the moment it's on at 100 (DFS) although if I tried to do it manually it's only gives the 36-48 range. I think the channels are there for the UK but the ATC's not picking them up? Anyway for now I leave it on auto and see how it go's. Thanks for you help.
channel 36 - 48 doesn't show anything above 48.
Unfortunately, the firmware version of your Time Capsule thinks that you are in a country that does not yet allow higher channels, so the only channels that are shown as available for manual selection are 36-48.
However, if higher channels are available and legal, the Time Capsule might find them using the "Automatic" setting, but you will not be able to choose them manually.
The channel availability for manual selection on a Time Capsule in North America looks like this:
You might want to experiment by choosing another Country to see if that displays a larger selection of channels.
