Hi.
I think that error means that the ESP32 is not establishing a connection with the router.
What is exactly the example that you are following?

ROUTER

Hi.
Yes. You are right. In that case, it shouldn’t be a program of the router.
Did you change anything on the code, or are you just trying the sample example?

Does the new router have DHCP server turned on? Are there enough IP Addresses available? Does it have 2.4GHz turned on? These are things the ESP32 requires. Is there any kind of firewall? Do you have to specify MAC addresses in the router? How are the antennas different (ie. perhaps the ESP32 needs to be closer to the new router).
 
WiFi issues are difficult to troubleshoot.

Did you change anything on the code?   No

Does the new router have DHCP server turned on?    YES
Does it have 2.4GHz turned on?   Yes
 
The 20 years old  DLink – 645  no antenna.

192.xxx.1.2xx

BR-LAN

 
 
Are there enough IP Addresses available? Yes

Did you try bringing the ESP32 closer to the router?
 
Note that the DLink645 would have had antennas. They were probably internal. A router would never work without antennas.

I will

Same problem.

Have you tried any other web server project?

Yes.

It is ok.

True. I guess we both made an assumption which was incorrect.
I guess the best idea would be to update all of the libraries used to the latest versions. Also, try a different ESP32.

As Steve suggested try updating everything. Including your ESP32 boards installation.
If it doesn’t work, I suggest that you try this library for OTA updates: https://github.com/ayushsharma82/ElegantOTA
We’ll release a tutorial about this next week.

I resetted to default  Everything works!

From the provider.  “Concrètement il n’y a pas de configuration à faire avec le routeur SR905. 
Il suffit d’entré le SSID et le mot de passe de votre connexion dans le fichier de configuration de votre ESP32 et le tout devrais fonctionner.”

Hi.
Is your problem fixed now?

Yes.
 

Great!
I’ll close this issue.
If you need further help, you just need to open a new question in our forum.
