You need an SW called Omnipeek and a Wireless-N USB network adapter (we suggest Linksys WUSB600N V2)

Just confirm with you the router never enable the "hidden SSID" feature.

Yes!

Could you help to capture the air package for our analysis?

How do i do that?

What do you mean with TK-Link?
If you meant 'TP-Link': it's not a TP-Link router, it is a router from the german company 'Telekom'.
The strange thing is, that i tried it a few days ago with a TP-Link router and it worked without any problems. I just don't understand whats wrong here: The module is aware of the WiFi but can't connect to it?

seems 8266 can't get the SSID of this router, which kind of the TK-Link router?

Router is set to 2.4GHz (otherwise my wlan-stick wouldn't recognize my WLAN).
The scan acutally finds the SSID, lol

scandone
(3,"",-78,"d4:21:22:8d:27:23",1)
reconnect

If i use my wifi-connection code, i still get this:

scandone
no found, reconnect after 1s
reconnect
scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 0 (19)

how about your router's setting, should it be setting as 5G? our 8266 only support 2.4G

for more debug, you can use the sample code:http://bbs.espressif.com/viewtopic.php?f=31&t=229 to scan all the routers nearby.

Okay, i changed the SSID to '12345678' but nothing has changed. I also made two constants for SSID and password. I went directly in front of the router and still the same messages.
I made a test with the hotspot of my smartphone and it worked perfectly over 8 hours (untill i disconnected it)!

I don't understand what's so different about my router...

log shows the SSID never found, could you currect your SSID name, and the best is you can print the SSID with os_printf() to debug the issue. suggest you use a simple SSID like "12345678" during testing.
Fow HW, which module you used? have you confirm the antenna has been plug in

【Feedback】ESP8266 doesn't connect to WiFi?

2016-07-06T14:35:20+08:00

Hello forum,

i have the strange problem, that my ESP8266 module doesn't connect to my home wifi, even if it is placed 1 meter around the station it just doesn't work even though it connects flawlessly to a smartphone hotspot and to a TP-Link WiFi. It just tells me that the wifi can't be found. This is my code:

Code:

void ICACHE_FLASH_ATTR
user_set_station_config(void){
    char ssid[32] = "MYSSID";
    char password[64] = "MYPW";
    struct station_config stationConf;

    os_memset(stationConf.ssid,0,32);
    os_memset(stationConf.password,0,64);

    stationConf.bssid_set = 0;

    os_memcpy(&stationConf.ssid,ssid,32);
    os_memcpy(&stationConf.password,password,64);
    wifi_station_set_config(&stationConf);
    wifi_station_connect();
}

void user_init(void)
{
    wifi_set_opmode(STATION_MODE);
    user_set_station_config();
}

(i removed my SSID and PW for obvious reasons).

I copy pasted the SSID and password from my router configuration. This really bothers me even more because I don't understand why this happens (or rather why nothing happens).
