CAX80: [WLAN access rejected: incorrect security] from MAC

130s · ‎2021-07-10

# Issue

Wifi gets disconnected. Occasionally it gets connected back, but then after indefinite period, many times it's a few seconds, it disconnects again. Then it takes a few minutes to sometimes 10 minutes to connects back without disconnection.
Observed on about 5 devices.

# Logs and more info

On router's admin webpage, "Advanced" -> "Administration" -> "Logs" I see these logs. The devices with those MAC address that got "[WLAN access rejected: incorrect security]" message correspond to those that are seeing the issue described above.:

# Environment

Nighthawk CAX80
Hardware Version: 1.01
Firmware Version V2.1.1.4
Cable Firmware Version V1.02.08

# What I did but didn't seem to work

Played with wifi setting, such as "Enable AX", "Enable Smart Connect" etc.
For 2.4 Ghz, change the channel from "auto" to the specific ones.
For 5 Ghz, change channels.

Got it working so far but not sure yet...as it had been working for a few weeks, then this occasionally bombers us. So in order for us to be confident I'd have to see a few more weeks. Anyways,

# Change I made

Disabled guest network 2.4 ghz.
Disabled "Smart Connect" (so that the SSIDs for 2.4 and 5 ghz must be different, which is ok for us)

# What I found before making those changes

Using wifi analyzer Android app the non-guest 2.4 ghz wifi and guest 2.4 ghz SSIDs are using the same channel. Without knowing much about those, I simply worried, hence the change described above.

# Caveat

Obviously I cannot use guest 2.4 ghz wifi, which is inconvenient. If this is a bug I'd like to see a fix.

Did you determine that _both_ those changes were required?

> o Using wifi analyzer Android app the non-guest 2.4 ghz wifi and

What led you to expect otherwise? So far as I know, there's only one
2.4GHz radio (which can use multiple SSIDs).

> o Obviously I cannot use guest 2.4 ghz wifi, [...]

"Obviously", _if_ you determined that disabling the 2.4GHz "guest
network" was required. Did you?
