Help me about resolving the configuration issue.

Faizi — Sun, 19 Nov 2023 05:08:06 GMT

After the new configuration our APs when I attempt to connect the device several times, it has difficulty establishing a stable connection with the access point. I don't know what the problem is.

Please take a look at our configuration details.

What model AP and what clients are you using. Looks like an autonomous AP

you can check out https://thewlan.com.au/2016/09/27/configuring-a-cisco-ap-for-site-survey/

This is our AP model:AIR-CAP3702l-A-K9

and we are using autonomous AP

> it has difficulty establishing a stable connection with the access point
Are you able to establish a connection at all?
When you say it's not stable - what do you mean? Does it drop? After how long? Is it slow?

I see you've hard-coded the channels - is there a reason for that?
If you have all your APs using the same channels that will likely be a disaster because you'll have massive co-channel interference.
Recommended config use least congested 1/6/11 for 2.4 and DFS for 5:
interface Dot11Radio0
channel least-congested 2412 2437 2462
interface Dot11Radio1
channel dfs
If you want to use static channel assignments then you'll need to survey and design carefully (with correct power levels) to avoid excessive overlap.

You've used the power client setting. Note this setting will only work if the client supports Aironet extensions which not all clients will. https://www.cisco.com/c/en/us/td/docs/wireless/access_point/atnms-ap-8x/configuration/guide/cg-book/cg-chap6-radio.html
For 2.4 you've set radio power to 2 (which doesn't seem to be a valid power level - show controller dot11 0 will show us what it is actually using?) and then client power to 14. It's recommended to leave that at default or configure it to power client local.
For 5 you've presumably set radio power to level max (which will depend on country) so again show controller dot11 1 will show what power it's actually using, but then set client power to 17. Again recommended to leave as default or use power client local.

If I follow the guidelines below, do you think it is good or not?

No it is not good!
Those instructions are for configuring 1 AP to be used for a site survey, not for configuring an AP for WiFi use.

Do I have to follow and implement the method I shared in your previous link?

That is the config guide for autonomous APs.
