Have you changed anything in your configuration? Security changed from WPA PSK to none? And all clients have "remembered" settings for the old configuration and computers tries to connect with password?

I'm seeing the same issues, on 2 out of 10 in my upgrade test group.

I've confirmed that the credentials are correct.
Ultimately she did get the phone connected,

09:31:01 wireless,debug wlan1: 68:84:70:3F:75:90 attempts to associate
09:31:01 wireless,debug wlan1: 68:84:70:3F:75:90 not in local ACL, by default accept
09:31:01 wireless,info 68:84:70:3F:75:90@wlan1: connected, signal strength -74
09:31:32 wireless,info 68:84:70:3F:75:90@wlan1: disconnected, received deauth: authentication not valid (2)

Repeated many times before

09:48:07 wireless,debug wlan1: 68:84:70:3F:75:90 attempts to associate
09:48:07 wireless,debug wlan1: 68:84:70:3F:75:90 not in local ACL, by default accept
09:48:07 wireless,info 68:84:70:3F:75:90@wlan1: connected, signal strength -86


I hear similar tales form other customers, primarily on 6.42rc6 not 6.42.1

I'm also having this issue on 6.42.6. Signal strength -63, so not too weak. Sometimes I also get deauth due to MIC failure (14), for the same device

This is mostly fixed for our customers.

Were using the setting in the script in post one of "Wireless woes and how to fix em :)"

It is caused by congestion.
When reported we look at the network; resolve if internal (such as getting those stupid Direct print printers on the network instead of competing with it}.
If not internal do a scan and determine the best channel; then modify the scan-list in order of preference.

It's a lot better in 6.42.3 as well, haven't tested newer.

Same here.
Xiaomi Redmi Note 8 Pro / MIUI Global 11.0.4 / Android 10 (with 2020-05-01 security patch)
2.4GHz is working, but 5GHz drops.
Both with wAP AC lite on workplace and hAP AC lite at home.

Hi, I have disabled "aes ccm" on 5GHZ security profile; so now I have only "tkip" and it works fine with my Redmi Note 8 pro.
It's not the best solution... but is a workaround.
On 2,4Ghz band AES+TKIP works fine.

Hi, I can confirm, disabling aes com on 5GHz solved the issue for my Redmi note 9 on hAP ac2, v6.47.9.

It's a long standing issue.

Use the hAP AC2 as a router and turn off it's wireless. Use the ruckus or UniF--k for wifi.

It worked for me:

In the advanced wireless properties:
noise floor limit "-110"

adaptive noise immunity "both"

Disconnect timeout: 10s

in failure attempt time 0.10

in the wireless tab:

wireless protocol "any"

disable:
"multicast buffering"

"keepalive frame"

Remember to choose a good free frequency band and a good "target" antenna alignment.

Klembord-2.jpg
Default authenticate not ticked . ... Means ... deny all authentication, unless ACL says otherwise (has an accept rule in local ACL) => authentication will fail even with the correct credentials and methods.
disconnected, received deauth: authentication not valid (2)
disconnected received deauth class 3 frame received (6)
disconnected received deauth class 3 frame received (7)
... as expected

ACL's are not given in these posts! So it is not clear what's wrong there.

Management protection secret is given but is wrong in the other attempt? => management protection failure

Some client devices require that WMM is enabled on the AP.
Wireless protocol is 802.11 ("any" includes "nstreme" and "nv2" , which are only understood by Mikrotik devices)
