Wireless Access

I have 140 AP (100 x 93H + 40 x 105) when enabling high throughput around 25 (93H AP ) are keeps disconnecting and connecting users! but the other are normal, the user is getting the IP but AP disconnect immediately.

before I enabled high throughput feature, it was normal .

I have controller 7210 V 6.5.1.3

thank you in advance :) 

If you have high throughput off the whole time, is there a reason why you are enabling it?

Hi Colin,

thank you for your reply..

I have hotel environment with 200mbps speed, when disabling hight throughput the bandwidth usage doesnt exceed 80mbps which is weird. after activating it, the usage went double or more.

When you enable HT, do you see any access points have channels like 1+ or 11- ?

yes, ther are some AP +1 & -11

That means you are bonding channels on the 2.4ghz band and that is causing more interference.  You need edit your AP group, go to RF Management> 802.11g radio> Adaptive Radio Management.  Make sure that "Allowed bands for 40MHz channels" is set to "none" and click on apply.

Hi  Colin,

Ive applied these settings, but still the same

Do the channels still show + and -?

Dear Colin,

no, ther is no +-

Do you have "Drop Broadcast and Unknown Multicast" enabled on all of your Virtual APs?

thank you Colin,

it solved but took time to apply :)
