Hello @ShawnN ,

Thanks for contacting our community.

May I know the hardware and firmware version of your router? When did you buy the router? You mentioned slow Wi-Fi and Wi-Fi dropouts.

Are the poor performance mainly due to these two aspects? What about the wired connection?

Here are some troubleshooting steps that may help.

For the WiFi dropout and unstable connection:

First, log into the web interface of the router (http://tplinkwifi.net), go to Advanced > System > Firmware Update and make sure the firmware is up to date.
Since you're experiencing wireless client devices dropping or becoming unstable:
1. Make sure the router is properly placed • it should be in an open area instead of inside a cabinet or shelf.
2. In the web interface, go to Advanced > Wireless > Wireless Settings, and try different Wi-Fi channels to avoid nearby interference. Additionally, for 2.4GHz wireless client devices, set the 2.4GHz channel width to 20MHz. For 5GHz wireless client devices, set the 5GHz channel width to 80MHz or 40MHz to avoid interference.
3. Make sure the client devices are not included in any Parental Control profiles.
4. Make sure the network adapter drivers, system, or firmware on the affected client devices (e.g., PC, phone, or smart devices) are up to date.

For the slow WiFi speed:

To accurately test your Internet speed:
• Use https://www.speedtest.net or the Speedtest app to test speed
• First, verify the max speed of your ISP by connecting your PC directly to the ISP modem and test speed on the PC
• To test the wired (Ethernet) speed of your router, connect the PC directly to one of the LAN ports of the router, ensuring all Ethernet cables are CAT5E or higher
• When testing wireless speed, connect your phone/laptop to the high-speed network (5G/6G) instead of 2.4G. To reach maximum throughput over wireless, put the phone/laptop next to the router.

Tips to improve your router's speed:
1. Log in to the web interface (http://tplinkwifi.net), go to Advanced > QoS, and make sure QoS is disabled.
2. Open the Tether app, go to Parental Control, and ensure no parental control profile is configured.
3. If wireless speed is slower than expected, go to the web interface > Advanced > Wireless Settings to change the 5GHz Wi-Fi channel. Test different channels to find the best one for your environment.
4. Go to the web interface > Advanced > NAT Forwarding > UPNP to disable UPNP, and go to Advanced > Security to disable SIP ALG. These features may affect Wi-Fi performance and speedtest results.
5. Speedtest by Ookla allows you to select different servers • try other speedtest servers, as some servers may provide better speeds.

Hello @ShawnN ,

Thanks for getting back to us.

May I know if your network topology diagram is as follows:

ISP modem—BE230)))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

Have you tested the wireless connectivity of other devices? For example, your modem or your old router, to confirm the stability of your wireless environment.

Did you notice the previous firmware version? Was it 1.1.2 or 1.2.1? For Bufferbloat, you might want to try this firmware: Archer BE230_V1/1.20_1.2.1 Build 20250821(Beta Firmware)

For more details, please refer to What Can I Do If QoS Enabled Causes BufferBloat and High Latency on My Router After Firmware Update?
