6 years ago More information about the problem.
- The Cisco 1140 is configured in Autonomous mode meaning it is not using a controller as the configuration entity.
- If you set the security settings on the Cisco 1140 AP for the SSID to be WPA TKIP only (Not WPA AES+TKIP) the problem we are seeing in the field is reproduced. See screenshot.
- I found an online reference to something that sounded similar with a fix but I cannot figure out how to carry out the fix because I cannot get the commands to work in the console. It is like it is a different OS http://itsnippet.com/2015/09/18/packet-to-client-xxxx-reached-max-retries/
I am in the process of trying to capture all log messages and packets between the ESP8266 and the AP to help diagnose. I noticed a few posts through searching of people having TKIP problems with no solutions or a solution of going back to 2.0.0.0.
Any ideas would be appreciated.

We have been using the ESP8266 for an IoT product for some time but recently we have one customer who has a Cisco AIR-LAP1142N-A-K9 Aironet 1142 Controller-based AP. When my device tries to connect, it succeeds in connecting but does not get an IP address. The same program can connect to other APs in the same location but different models - non Cisco. We tried to connect to all 3 of the Cisco routers in the building on different channels with the same results. I only have access to the router settings if I have a specific question (I can't get a dump of the settings). I do have one of the same model of routers on order to try to duplicate the problem. I have searched for hours and tried everything I found to try.
I have two questions.
I am compiling this with the Arduino Genuino IDE version 1.6.12 and ESP8266 Community version 2.3.0. Module: Generic ESP8266 Module Flash Size: 4MB/1MB CPU Frequency: 80Mhz Flash Mode: DIO Flash Frequency: 40Mhz Upload Using: SERIAL Reset Method: ck
The security on the routers is WPA2
Here is the debug and log output:
Connecting to CiscoAP ..scandone state: 0 -> 2 (b0) state: 2 -> 3 (0) state: 3 -> 5 (10) add 0 aid 14 cnt
connected with CiscoAP, channel 1 dhcp client start... wifi evt: 0 WIFI_EVENT_STAMODE_CONNECTED ........state: 5 -> 0 (0) rm 0 wifi evt: 1 STA disconnect: 8 WiFi lost connection f r0, ..scandone state: 0 -> 2 (b0) state: 2 -> 3 (0) state: 3 -> 5 (10) add 0 aid 14 cnt
connected with CiscoAP, channel 1 dhcp client start... wifi evt: 0 WIFI_EVENT_STAMODE_CONNECTED ..........pm open,type:2 0 .........................
Which is generated from a very simplified program I created to make sure I was not doing something in the larger program to cause it:
include
const char ssid = "CiscoAP"; const char password = "xxxxxx";
define DEBUG_PRINT(x) Serial.println(x)
void setup() { Serial.begin(115200); delay(10);
Serial.println(); Serial.println(); Serial.print("Connecting to "); Serial.println(ssid);
WiFi.onEvent(WiFiEvent); WiFi.mode(WIFI_STA); WiFi.begin(ssid, password); }
int value = 0;
void loop() { delay(500); ++value;
if (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } else{ Serial.println(""); Serial.println("WiFi connected");
Serial.println("IP address: "); Serial.println(WiFi.localIP()); }
if(value==10) { WiFi.disconnect(); delay(1000); WiFi.begin(ssid, password); } }
void WiFiEvent(WiFiEvent_t event) { IPAddress ip_addr;
switch(event) { case WIFI_EVENT_STAMODE_CONNECTED: DEBUG_PRINT("WIFI_EVENT_STAMODE_CONNECTED"); break;
} }
