This Article Applied to:

Archer BE550 V1 1.1.1 Build 20241230

 

Phenomenon Description:

We've received feedback from users that after updating the Archer BE550 V1 firmware to the official 1.1.1 Build 20241230 version, certain devices with 10Mbps or 100Mbps connections are unable to access the internet when connected via cable. 

 

Commonly affected devices include:

  • Tado Internet Bridge: IB-01 (10Mbps half-duplex)
  • Liftmaster 828LM (10Mbps half-duplex)
  • LINKSYS PAP2T VoIP Phone Adapter (10/100Mbps half-duplex)
  • Salus iT500 thermostat gateway (10/100Mbps half-duplex)

 

The Ethernet connection status on the BE550's web UI may appear invalid as shown below (the device is connected to the LAN1 2.5G bps port on the BE550):

 

These devices worked fine with the BE550 on 1.0.x firmware but have stopped functioning with the new 1.1.1 version. This issue may lead to customers' smart devices going offline, impacting their daily lives.

 

Workaround:

We understand this can be frustrating.  Our development team has provided beta software to address this issue. If you're experiencing similar issues, please upgrade and install the beta software on your Archer BE550 V1, then check if those devices connect to the internet properly.

Hi @Kevin_Z !!!

 

After installing the beta firmware, my Archer BE550 recognizes the Linksys PAP2T adapter.

 

 

Thanks !!!

@All

 

I installed the BETA firmware 1.1.1 Build 250212 on Friday afternoon (GMT+1) and everything worked fine so far.  Even if I'm not affected by the problem, it can't hurt if not just a handful of people test it, but perhaps one or two more people.

Yesterday, however, I noticed something strange and now I'm not sure if it was due to the BETA firmware or something else. 

 

Every night at 3:50 am the system log is sent to me by email. On the night from Friday to Saturday, I also received the system log by email, but not on the night from Saturday to Sunday. I then tried to initiate the sending of the system log manually via the Archer BE550 web interface, but that didn't work. After clicking on Send, it took a while and suddenly my connection from the PC to the router was disconnected. I tried it a total of 4 times and each time I got the same result. That means that my PC was disconnected from the Archer BE550 on the network side and reconnected after about 30 to 60 seconds. Turning off the Flow Controller on the LAN side didn't help either, although that was my first suspicion. The router itself was online and accessible via the Tether app. Other clients also had internet access during this time.

 

Finally, I downgrade to the official firmware 1.1.1 Build 20241230 and reactivated the flow controller on the LAN side. I was then able to have the system log sent manually by email immediately and without any problems. I also received the system log by email again last night without any problems.

 

Was this just a stupid coincidence or could there possibly be a problem with this new BETA version? Maybe someone can try to reproduce and test it too.

@Baxajaun 

 

I'm happy to hear that the Linksys PAP2T adapter is being identified successfully by the BE550 again.

 

Our development team to review the firmware code and provide a final solution soon. Please wait.
