How to disable 5ghz on 7720 controller ?

Hello Community, 

 

I figure out a case which i need to disable te 5ghz without loosing the N.

I founded some ways :

 

One over the ARM :

http://www.arubanetworks.com/techdocs/ArubaOS_63_Web_Help/Content/ArubaFrameStyles/ARM/ARM_Profiles.htm

(See the screen 1)

 

Another ways on the VAP config by disabling the "all" to just "g"

 

What is the correct ways to disabled the 5ghz on a SSID without loosing the n features.

 

Many thanks in advance.Michael

For an SSID just set it at virtual-ap level.

Many for your reply, but where ?

See GUI virtual-ap for more information. Or CLI virtual-ap for the CLI config.

Parameter to change is "allowed-band".

thanks for your so useful answer !

 

Does i loose the 802.11n if i put the band on : g ?

Re: How to disable 5ghz on 7720 controller ?

802.11n exists ontop of  both 2.4 GHz (g) and 5 GHz (a) bands.

If you set the virtual-ap profile to <g> you will remain with 802.11n on the 2.4GHz band only. 

This means nomore ac or a or "n ontop of a" so hopefully you have a very good reason to do this because you basically just disabled the best WiFi band :)

Re: How to disable 5ghz on 7720 controller ?

the reason is that the building have some very heavy wall and the 5ghz works fine on the corridor for example but.... not as expected behind the wall...

For example, good coverage on the coridor which have the ap mounted and not really on rooms which doen't not have ap installed.

The 2.4ghz signal is better on the rooms... and we need wifi on the rooms...

 

that why i would like to use only the 2.4ghz channel...

 

Actually the Android (Xperia) phone doesn't not roams as expected... and we've got couples of second of network cut...

 

By just force the ssid on 2.4ghz, the phone will stay on the band and do not jump between the both band and cut the network..

(works fine and Iphone or Nexus)

 

If you have some tips and tricks to improve this behaviour do not hesitate to share

Re: How to disable 5ghz on 7720 controller ?

Well, if 5GHz doesn't reach the side rooms sufficiantly you realy should look into that. Check if your 5GHz radio is putting out max power. And if it is, you realy should look into deploying more APs if at all possible. 

 

Placing AP's in a straight corridor isn't best practise. APs will see other APs strongly and think their is high density overage and lower their output power. 

From CLI do a "show ap active". Post the output of that command here if you need some help interpreting it.

 

You can force APs to use more power by changing the Min Tx EIRP value from the arm profile. Keep in mind that both your 802.11g radio profiles as the 802.11a radoio profile might be using the same arm profile.

 

You REALY want to have your 5 GHz band for clients.

Re: How to disable 5ghz on 7720 controller ?

Well, most of your a-radios seem to be outputting max or near  max. 

Je might increas your min Tx in the arm profile for the a-radio to 24 and see if that makes a difference.. hopefully you are lucky.

 

Otherwise you're only real option is to place more APs to stay working with 5GHz.
