Hi@sk- 

Could I know if all wireless clients lose the network when the problem occurs? Is the wired connection still normal?

At this time, does the LED status of the router indicate any abnormality?

Can you provide a screenshot of the router's Internet status? Log in to the web UI via http://tplinkwifi.net, then go to Advanced—Network--Status

In addition, we have reported the issue to the support engineers, they will likely reach out to you via email to continue to troubleshoot your issue. Please check your email box and confirm.

  @Joseph-TP since I haven't seen updates to this thread, I will share my anecdotal evidence. I will be glad to work with you to provide logging, etc if needed.

1) only the MacBook client on Wifi loses connection. The Wifi connection itself is stable, but Internet becomes inaccessible.

2) the wired connections all remain normal.

3) all other Wifi connections on the same and other SSIDs remain normal, including iPhone/iPad and IoT devices.

4) the LED status of the router displays no abnormalities.

5) the Internet status in the router settings is active with no interruptions (v6plus)

6) the issue is resolved by disabling and reenabling the MacBook's Wifi.

7) the issue occurs both with DHCP running on the router, as well as if DHCP is disabled on the router and run from another source (because the issue tends to occur after 1 to 2 hours of use, I thought it may be occurring when the DHCP lease is being renewed, but that does not appear to be the case).

- the MacBook is using the MLO network with 2.4Ghz, 5GHz_1 and 6Ghz.

- however, the issue also occurs even if the MacBook connects to the exclusive 2.4Ghz or 5Ghz SSID.

Hi  @superduper64,

 If certain client devices are experiencing frequent dropouts or losing internet connectivity when connected to a TP-Link router, there are several potential reasons and troubleshooting steps you can take:
    1. Check Wi-Fi signal strength: Ensure that the affected client devices are within range of the TP-Link router and not obstructed by obstacles. Consider repositioning the router or using Wi-Fi range extenders to improve coverage.
    2. Adjust wireless channel: Change the wireless channel on the router to minimize interference from neighboring networks.
    3. Check wired connections: If the affected devices are wired, try using different Ethernet cables and ports to rule out any issues with the connections.
    4. Update client device drivers: Make sure the network adapter drivers on the affected client devices are up to date.
    5. Disable router features: Temporarily disable advanced router features like Quality of Service (QoS) that may be causing compatibility issues with specific client devices.
    6. Update router firmware: Check for and install any available firmware updates for the TP-Link router to address compatibility issues and improve stability.
 

  @Joseph-TP Thanks for your reply. Respectfully, if I am making a post here it's because I've already extensively tested the gear, and the issue has been narrowed down to firmware.

I am using a workaround since I cannot get basic functionality out of the device. I've considered asking for the firmware downgrade, since the issue didn't occur in the shipping firmware (as the OP mentions in their post), but I'd then lose MLO which is one of the reasons I made the purchase. I am using a wired dock for my Mac client as a workaround now but it isn't a permanent solution.

If you can help me to enable verbose logging on the BE900, I will even do the troubleshooting for you and create logs for when the issue occurs. As you may be aware, the logging is quite limited with stock settings.

 Hi @superduper64 ,

To assist you efficiently, I've forwarded your case to the TP-Link support engineers who will contact you with your registered email address later. Please pay attention to your email box for follow-up.
