Model: Archer BE9300  
Hardware Version: V1
Firmware Version: 1.1.2 Build 20250317 rel.19315(5553)

I have the Archer BE9300 USW/1.6 router and since I roughly January I've been frequently, but not in any specific pattern, lost connection to the internet due to a teardown and release. I've seen other posts related to various other TP Link routers that had a similar problem and have had no luck with any solution I've found there. I've factory reset the router three times, disabled and enabled various options, checked and rechecked if I'm on the latest firmware, and am starting to lose my mind trying to think of what else I could do to make it stop. I know this issue has probably been discussed over and over but I can't seem to find any final fix that will correct the problem I'm having and any help would be greatly appreciated.

The "Teardown and Release" (or "Teardown and Renew") error in TP-Link routers, particularly models like the Archer A7 and C7, refers to a chronic disconnection issue where the router drops its WAN/Internet connection and attempts to renegotiate its IP address with the Internet Service Provider (ISP), often resulting in a brief, repeating outage. This issue is often related to a firmware bug causing excessive DHCP requests.  
 
Key Causes and Context
  • Firmware Bug: This issue is frequently attributed to a bug in the TP-Link firmware that causes the router to drop connection, often reported on the Archer A7/C7 and some Omada routers.
  • DHCP Issues: The router unnecessarily "tears down" its existing connection and attempts to "release/renew" the IP address from the ISP, causing drops.
  • ISP Incompatibility: Sometimes it's a conflict between how the ISP handles DHCP leases and how the TP-Link router handles them.
  • Physical Issues: In some cases, poor connectivity can be caused by physical issues with cables. 
 
Troubleshooting Steps
  1. Update Firmware: Check for and install the latest firmware from the official TP-Link support website for your specific router model.
  2. Check WAN Connection Type: Verify if your ISP uses Dynamic IP or PPPoE, as these settings can affect stability.
  3. Confirm ISP Stability: Bypass the TP-Link router by connecting a PC directly to the ISP modem to ensure the modem itself is not causing the drops.
  4. Downgrade Firmware: If the latest firmware does not solve the issue, downgrading to a previous, more stable version may help.

 

You can try manually updating to the latest FW from here (Archer BE550(AU)_V1_1.2.3 Build 20260127) and check how it goes.

Hello @mucsdnop ,

Thanks for contacting our community.

 

Is your router complete model: Archer BE9300(USW)_V1.60_1.1.2 Build 20250317 rel.19315?

If you manually detect the new firmware, can you find 1.2.2 Build 20251209 rel.58760?

 

I noticed you mentioned that the internet connection started becoming unstable in January. Did you change any settings? Did you add any new devices to the network? Or did you update any firmware, including for the modem and router?
