Connecting ESP8266 to FRITZ!Box 3370

[tobau]

Hello,

i got a strange Problem: I've written a C-Code which connects to an AP and serves TCP at some ports. It works totally fine in my Network (Hitron Hub). A few days ago, i've moved to my parents place to install an ESP to do some lightning control. (FRITZ!Box 3370) I've changed the SSID and the WPA2 Key in my Code. I've Copy and Pasted both, so its impossible that there is a typo...

How Ever: When i'm powering up the ESP, it finds the network, and tries to connect to it, but it doesn't work. The Log-File of the FRITZ!Box 3370 says, that there was the wrong key.

Here is the Debug-Out from the ESP:

scandone no FRITZ!Box - Intern found, reconnect after 1s reconnect scandone no FRITZ!Box - Intern found, reconnect after 1s reconnect scandone no FRITZ!Box - Intern found, reconnect after 1s reconnect scandone state: 0 -> 2 (b0) state: 2 -> 3 (0) state: 3 -> 5 (10) add 0 aid 7 cnt state: 5 -> 2 (2a0) rm 0 reconnect state: 2 -> 0 (0) scandone state: 0 -> 2 (b0) state: 2 -> 3 (0) state: 3 -> 5 (10) add 0 aid 7 cnt

and this repeats the whole time.

Is it a problem with TKIP/AES/CCMP? Which encryption does the ESP support? Is there any way to get a succesfull connection?

Thank you very much! Greetings

Hi,

had a similar issue. In my case it was the "connection mode" of the ESP. wifi_station_set_config(&stationConf); wifi_set_phy_mode(PHY_MODE_11B); wifi_station_set_auto_connect(1); wifi_station_connect(); The second line seem to force ESP to use 802.11B for connection with the access point and this mode has been deactivated in my WiFi environment. Setting the access point to accept 802.11b/g/n solved the issue for me. Don't know if this second line is really needed or if it would be better simply to remove this line. Perhaps ESP then connects with the best mode available?!
