How to increase receive and transmit speed Cisco AIR-CAP2702I -A- K9

[Roman_1978]

I have the Cisco AIR-CAP2702I -A- K9 access point. It works in autonomous mode on firmware ap3g2-k9w7-tar.153-3.JPK2.tar. My problem is too low speed of wi-fi. On the distance about 1 meter. In 2.4 Ghz (802.11n) I have speed connection 72Mbp/s. In 5 Ghz (802.11ac)  I have speed connection 173Mbp/s.

This is my config file of settings May be somebody can give me advice how can I  improve this settings to increase the wi-fi speed in both range.

What wireless NIC was used for testing?

72 Mbps with 2.4 Ghz looks good for a NIC card that can only support 1x1:1.

[Roman_1978]

I don't think 72 Mbps with 2.4 Ghz looks good because on the absolutely same equipment but with another AP I have 300 Mbps on the 2.4 Ghz Wi-Fi 4 (802.11n). Moreover I see on this forum some users have the approx 866 Mbp/s stable on the AP like my. (https://community.cisco.com/t5/wireless/slow-file-transfert-on-2802i-but-not-on-2702i/td-p/3330026)

Let me hazard a guess:  Driver version 20.70.21.2?

Hi

    This is not a problem. It only tells that you are working with one spatiol stream, on 20 MHz channel and modulation in 64QAM.

You need to look at the tables shared above and your interface config, then tune channels, data rates and channel width as appropriate to your environment.  Here's an example from one I was using at home:

interface Dot11Radio0
speed basic-12.0 18.0 24.0 36.0 48.0 54.0 m0. m1. m2. m3. m4. m5. m6. m7. m8. m9. m10. m11. m12. m13. m14. m15.
interface Dot11Radio1
speed basic-6.0 9.0 12.0 18.0 24.0 36.0 48.0 54.0 m0. m1. m2. m3. m4. m5. m6. m7. m8. m9. m10. m11. m12. m13. m14. m15. m16. m17. m18. m19. m20. m21. m22. m23. a1ss9 a2ss9 a3ss9
channel width 80
channel dfs
I don't remember what speed I was getting from it with those settings.

Look at the output from "show controller dot11 [0/1]"

ps: just to clarify mine was a 3702 - not sure whether 2702 supports all the same data rates.  I know 1702 has a reduced set.

Thanks for your answer Flavio, I read this site, but I'm actually not a cool net specialist would you explain for me how I can increase my wi-fi speed
