Are these ping tests performed on the same wired and wireless clients? What are they? Are they connecting to the internet fine via the AX73? Be sure there are no settings on the client devices that blocking the ping from others.

Is there a reason to set the subnet 255.255.255.192? Try changing it to 255.255.255.0, then check again if the ping is accessible on all devices.

  @Kevin_Z Hey Kevin,

Yes that subnet mask is intended to be like that. 

 

Anyhow, after tinkering with the router configurations for few weeks, i  managed to found the root cause of the issue.

This issue happen whenever the bonding is configured for LAN 2 & 3. 

This is also applied for both Static LAG and LACP mode. 

 

But this issue won't happen immediately after you enable it, it will take some random time for it to happen. 

But in my case I am noticing that on average this will occurred around 30mins after i've enable the bonding. 

 

Apart from the connectivity issue between both LAN and WIFI, there also another issue happening especially on WIFI devices.

the device will disconnected and won't be able to reconnect. it will also throw you and error of wrong password even though the password that you set is correct.

Hello @pdudkronos 

 

Do you mean you are configuring Link Aggregation between LAN 2 & 3 on the AX73? What is the device connected to LAN 2 & 3, is the Windows PC? Does it support Link Aggregation? Can you please explain this in more detail? I would like to have the detailed network layout, then I may suggest better.

 

Regarding the wireless connectivity issue, can I know if it is the 2.4G or 5G connection? when the error happens, how do you connect back to the network? Do you need to reboot the router?
