client unstable and even disassociate on ap1602，then there are some log

[Rps-Cheers]

HI Everyone，


I have a problem with AIR-SAP1602I-C-K9,it's a LAP.


Under this AP, the client is sometimes unstable and may even disassociate.
The following is the abnormal information of AP. I want to know what this log means. How can I solve this problem?

Really need more info. The log you posted doesn’t help. What have you done to troubleshoot? Are all devices having the same issue? Is it all AP’s or just this one? Signal and SNR good? Is the issue with 802.1x, psk or open? With an open SSID, is the issue still there?

You need to eliminate variables and try to add more details.

HI Scott; Now I only found problems with the client under this AP. The problem is not always there. Signal and SNR are good. What does this log mean? “*May 25 03:11:14.582: Dtx dump: 4D997B0 3678 0 flags 23 101000 blkedmsk:FE01 blkedidx:0 aid:D Cpq 63877AC” And if this problem arises again, what information should I collect? Thank you.

You need to open up a TAC case to understand what that means. Unless you can find information on that by searching the forums or Google, TAC would only be able to find that out. If you isolated it to one AP only, then the fastest way is to just RMA that AP to be honest seems it’s not an issue with any of your other AP’s.
