IAP-225 cannot get 802.11ac data rate

Hi,

 

i am trying to get my IAP-225 to run on 11ac data rate but i cannot get it working right. does anyone have some kind a How-To doc to configure the 11ac on IAP-225?

i already run firmware 6.4.0.3-4.1.0.1

enable wide channel

run only on 5GHz on channel 149E only hoping only 80MHz would be broadcasted but i cannot get it run on 11ac data rate.

the device i have been using is an HTC One M7.

could anyone help? thanks

few more thing,

i only get max 86 Mbps and on the IAP config screen says my client run on 11AN.

if i capture the signal using inSSIDer, the AP only broadcast on channel 149+ (40MHz) eventhough i already set it manually on 149E

What is the device you are trying to connect with?

 

If it does not support ac, then it will only 'see' n rates advertised.

Can you do a 'show ap association' and post the output please?

 

Looking at the mcs index charts, it could only be connecting at 20MHz chanel width at MCS 8......assuming, like most phones, it only has one spatial stream.

 

I have one myself, but am not near any ac wireless for another couple of weeks.

Your device is probably 1 spatial stream therefore only capable of 150Mbps.

Most phones, even if AC, are one spacial stream. You won't get the theoretical max without 3x3:3 clients. You'll find that there are very few of those out there.

Hi Rickylee

 

Have you been able to get any device to connect at 802.11ac speed of say 800Mbps? We are noticing with our Android phones they tend to want to connect to the slower 2.4Ghz channel rather than the faster 5Ghz even though they are less than 20ft from the WAP. However I have a laptop using the Intel 7260 Dual Band Wireless-AC card and it will connect at 800Mbps regularly.  I apologize I don’t have any insight to help fix your problem but wanted you to know you’re not alone in having problems with the IAP225.

With MCS9 and 40 MHz width - max 200 Mbps

With MCS9 and 80 MHz width - max 433.3 Mbps

 

Provided the device supports MCS8-9 which is not mandatory.

 

I have my doubts that you'd ever see a smart device connected at those rate though.
