Model: EAP772   OC200   SG2210XMP-M2  
Hardware Version: V1
Firmware Version: 1.1.5 Build 20251230 Rel. 39992

After updating firmware to 1.1.4 Build 20251030 Rel. 5764, my wireless devices lose internet connection when not in active use (same behavior is happening on 1.1.5 Build 20251230 Rel. 39992). 

 

After my mobile device is not used for a certain period of time and I wake it up, it does not have an internet connection, via its wireless connection to EAP772, and switches to mobile data, then after a couple of seconds it detects internet on my wifi network and switches back. My internet connection is fine for my wired devices at the same time the issue happens for wifi devices, so that excludes any upstream issues.

 

Has any new setting been introduced with the new firmware that can cause this symptom?

 

I am unable to revert to firmware version 1.0.14 to verify that it fixes the issue, is there a way it can be done?

Hi  @Sarex 

 

Thanks for posting here.

 

Does this occur on all of your wireless clients? Please also list some of wifi clients you are using.

 

If you connect one of the affected Wi-Fi clients to another Wi-Fi network, will the same thing occur?

  @Vincent-TP I have not observed it on laptops, only on mobile devices like the Pixel 7 and iPhone 16 pro.

 

I have not observed the same happening when connecting the Pixel 7 to another wifi network, but I hadn't had the opportunity to test it for an extended period.

Hi  @Sarex 

Thanks for the reply.

The EAP772 recent firmware update did not include changes in this regard.

After the device has been in a prolonged sleep state, the Wi-Fi chip may enter a deep power-saving mode (such as the WLAN sleep strategy), which can cause it to be unable to respond to network requests immediately upon waking up. The system may then mistakenly interpret this as “no internet” and automatically switch to mobile data. It is recommended that you continue to monitor the situation.

  @Vincent-TP I narrowed it down to the "Unscheduled Automatic Power Save Delivery" setting.

 

 

Turning this off resolved the issue, but this feauture worked before the new firmware update.

  @Vincent-TP It has started happening again with that setting turned off too. So it's not due to "Unscheduled Automatic Power Save Delivery" setting...

Hi  @Sarex 

 

Thanks for that info.

 

Have you checked the phones' related settings, such as power-saving mode? Is this issue bound to occur, or is it a random, occasional phenomenon?

  @Vincent-TP No apparent power saving settings are turned on. Initially I would have said that it occurs after prolonged periods of rest, but at this point I would say it's random as sometimes it doesn't happened at all during the day and sometimes it happens multiple times even after a short period of rest.

 

Worth noting is that I swapped two EAP772 with each other to rule out hardware issues and I have observed no difference.
