AP connection problem

[PuyiZhang7814]

Why do I have so many errors about "Client entered wrong password."?

My computer was connected automatically and I made sure my password was correct.

Also having this issue.. we have over 100 MR33 APs, running 26.6.1 Firmware

Surely there is a solution to this issue??

Still facing this issue with MR55 / v26.6.

And now discovering it in MR74 / v26.6 environment.

For the moment, the only observed workaround is a downgrade to v25.14 ?

@Alexandre_JAFRI Meraki support is refusing to acknowledge the problem. I tried to reach them many times but they are keep asking for wire shark logs and not doing anything else.

yes, I think downgrading to 25.14 is our best option. Zero issues since I have done that

[wayne.ranchuk]

@alican1it is frustrating. I have yet been able to capture the problem on wire shark I am starting to believe it is on the wireless side that you would not see on wire shark. has anyone tried running a airmagnet WiFi analyzer to scan to see if they can pick it up on the wireless side?

I've stopped talking with support about that issue as they clearly are not going to help.

They are still denying problem being known and always ask for wireshark packet captures - which show nothing - as they are difficult to capture as problem is random.

They probably know the problem, but it is difficult to solve - so better not to confirm it exists 😉

Or maybe we all have something wrong with our networks....

Br, Pawel.

Same problem with 2.68. Any one tried if it works better with 2.72?

I have tried with MR 27.2 and still getting the issue.

802.11r isn´t activated and still the issue

[CMR]

I believe it is down to power saving. It appears that the current 26.x and 27.x firmwares don't like Intel 802.11ac chipset power saving at all and you get high latency, disconnects, bad password etc. It does seem to affect some other devices but I have personally only seen it on all 802.11ac Intel chipsets. 802.11ax is okay and I don't have anything older.

[banfield75]

For me it´s mainly iOS devices. I hope everyone flood Meraki with cases regarding the annoying issue.

Following. Same issue. Same lame response from TAC. Hoping to receive info about a fix posted here!

Just adding that I have a similar problem since upgrading from 25.13 to 26.81

Wireless Health shows a 99.6% failure rate on one of my SSIDs for Authentication yet we haven't had a single call about Wi-Fi issues. This is a graph from the last hour.

I have also with this kind of issue and open a TAC case, but only advised me to do PCAP using MAC ios or linux which in our side is hard to provide. In our previous engagement with PCAP, they also don't have any recommendation after we have given then the PCAP results. Meraki support is 1/5.

Hello everyone,

• This incorrect failure message does not affect the functionality of the AP and client devices connecting to that AP
• Meraki has been made aware of this issue, which is being actively worked on and should be fixed in the future versions of R27.x firmware. Please be on the lookout in the changelog notes for this update.
• Due to the nature of this fix Meraki will not back-port the changes to R26.x firmware version.

Does not affect functionality?
