esps (D1mini) auto disconnect from router !

[reza]

hi guys.
i have a tp-link modem-router with a default settings (in pic)
channel in router is auto and now selected channel 2 and i see that traffic in channel 2 is not busy(with wifi data app)
i have some espeasy (D1mini) that connected to this router . all of esps have static ip in settings(on clients). (sleep mode is disable on esps)
ip router: 192.168.1.1

one esp ip is for example :
ip : 192.168.1.190
gw : 192.168.1.1
subnet : 255.255.255.0
dns : 192.168.1.1
so all of things is ok and work . but after two or three days, some esps auto disconnect from router.
esps are healthy and worked well with my old router (zyxel t10a), now i have a new router (tp-link).modem-router is healthy because this is new. i had this problem in last with a D-link router . and put aside D-link. now i have same problem with new router !!! where problem ! tp-link and d-link is not good router or settings have problem ! I'm not very familiar with the network and modem settings and work with default settings.

Can you show some log from the ESP around when it disconnects?

thank you for answer.
after disconnect , esps don't go to AP modes . they are connect to router Apparently. but when enter esp ip , can not open setting page also when send command from domoticz , esp dont work and in domoticz log i see error and "can not open url http://192....."
so i when esps are disconnect, i can not open settings page and see esp log.

Channel in the AP is set to "auto", so the AP may switch to another channel when the conditions change.

thank you for answer .
so my problem is related to auto channel ? Can fixing my channel solve my problem?

It is my first idea to fix this indeed.

Have you enabled to send out Gratuituous ARP packets (tools->Advanced bottom of the page) ?
If not, please do enable it.

i am using espeasy v2.0.0 and in tools-advanced have not this options
also with this settings(on espeasy) with last router i did not have any problem and worked excellent
what am i do ?

It is hard to tell what may be the difference here.
Some AP's have different rules regarding handling of clients when receiving N checksum errors per X second for example.

The Gratuituous ARP I suggested (which is not present in the older builds) is a trick to keep the network updated on what MAC address is reachable on what port of a switch or access point.
Another way to test this same feature is to continously send a ping to that node from anywhere in your network.

If i update my esps to new version of espeasy and enable Gratuituous ARP so do you think my problem resolve ?
Just one qustion , which .bin file (new stable version) i must use that control arduino pro mini extender (EXTGPIO) ?

Pro Mini Extender is in the "normal" build.
You can either try the latest nightly:
https://github.com/letscontrolit/ESPEas ... a-20210114
Or you can try the test build I made for a PR I'm still working on (to improve WiFi): https://github.com/letscontrolit/ESPEas ... -766346327

If you are running an old build, make sure to backup your config so you can go back if you like.
After testing the settings may not work anymore on the old build.

very thank you. i dont have any special config on my esps.so first i flash "blank_4MB.bin" file on my esps, so flash normal build "ESP_Easy_mega_20200801_normal_ESP8266_4M1M.bin" and enable "Gratuituous ARP"
so i am waiting for result of my network and after some day again report here that my result.thank you

Have you tried the test build I linked for the pull request I'm working on?
