ap1200 channels...

[after1111]

Hello everyone,

Im using ap1200. Ive been allocated channel 49 and 51. But on ap1200 there is no channel 49 and 51. Is that means I cant use channel 49 and 51?

Much appreciated.

I believe, you are allocated a channel from the 802.11 a spectrum. First make sure you are looking under the right radio interface. You can configure the channels 49, 51 only under 802.11 a radio interface.

Also according to this spec sheet, i dont see a channel 49 and 51.

thanks for your reply Shanky

I have only 1 802.11a radio interface (dot11radio1). here's the output:

ap1(config)#interface dot11Radio 1

ap1(config-if)#channel 49

Invalid channel-number/frequency

ap1(config-if)#channel ?

<36-5320> One of: 36 40 44 48 52 56 60 64 5180 5200 5220 5240 5260

5280 5300 5320

least-congested Scan for best frequency

Is that means Im cant use channel 49 and 51? Any other ways I to bypass this problem and use this channels?

Thank you in advance.

I dont think so.

If you use the option to select the least-congested channel, the AP will change to a different channel
every time its power is reset, thus leaving no predictability and negating the time and effort spent on the
site survey. Random selection of channels causes roaming times to increase because the phone has to
scan all channels rather than a smaller subgroup of active channels.
Every regulatory domain specifies different allowable radio channels. Observe the following guidelines
when selecting which channels to use:
• Always use channels that are a minimum of five radio channels apart so that they do not overlap.
(For example, use channels 1, 6, and 11 or use 2, 7, and 12.) This practice reduces the ambient noise on each channel
