Hi all,

I'm using the WiFi module to connect to infra WiFi in socket server mode.

The module return (through serial link) that connection to WiFi is OK.

But sometimes, in the WiFi router interface (a Freebox), the module is seen but stay in a not reachable status. At the end, it's not possible to send data to socket server. Even a ping to module address doesn't work.

Sometimes it works perfectly... for few hours and then back to unreachable.

SPWF01S output on startup :

+WIND:1:Poweron (141106-0950875-SPWF01S)

+WIND:3:Watchdog Running

+WIND:0:Console active

+WIND:32:WiFi Hardware Started

+WIND:19:WiFi Join:F4:CA:E5:D3:65:34

+WIND:25:WiFi Association with 'freebox_EVB' successful

+WIND:51:WPA Handshake Complete

+WIND:24:WiFi Up:192.168.1.43

OK

The OK at the end is the answer of socket server start command :

AT+S.SOCKD=27024

My config config is :

OK

I really don't understand why module is sometimes reachable and sometimes not.

Any ideas ?

Thanks.

New information,

I changed my WiFi router security to WPA2-PSK AES.

Now, the connection always succeed !!

There is something really strange arround security setting.

Same problems...

Everything is fine until I did not use SoftPerfect Network Scanner (https://www.softperfect.com/). After using this software -- WiFi module is down from outside. I can ping my PC ( from the WiFi module), but I can not open WiFi module web page, I can not ping the WiFi module from the PC and so on...

Also could you please check DNS variable in case when WiFi module is working without DHCP (at+s.scfg=ip_use_dhcp,0) See post #3

Hi Artem,

if module is working without DHCP, you have to set IP, netmask, gateway and DNS addresses (by at+s.scfg command).

If DNS is not set, then Resolver1 of OpenDNS is used (http://en.wikipedia.org/wiki/OpenDNS)

I did it.

Compare with topic-starter, situation is similar in my case

You can look at post #1 and #3. IP, netmask, gateway and DNS was set, but after module boot and using AT command ( AT+S.STS ) I see that DNS address is different.

So, you did:

- at+s.scfg=ip_use_dhcp,0

- at+s.scfg=ip_ipaddr,A1

- at+s.scfg=ip_netmask,A2

- at+s.scfg=ip_gw,A3

- at+s.scfg=ip_dns,A4

- at&w

- at+cfun=1

...and after reboot, and wifi up message indication, you see:

- ''at+s.sts=ip_dns'' different from A4? openDNS address there?
