Model: Deco BE85  
Hardware Version: V2
Firmware Version: 1.2.1 Build 20250731 Rel. 15505

I recently added a BE85 to my x50 mesh network and am having a number of problems that I cannot get on top of. 

 

The major issue that I need assistance with is that I cannot get internet access on any 2.4ghz network. I've tried using Guest and IoT as well as only having 2.4 active on the main network. I've tried all of the different security protocols and I've reset and rebuilt the network a number of times. Internet works fine on 5ghz.

 

It's killing my smart home setup and most concerningly my Nest Protect Smoke detectors. 

 

I am connected to Spintel with dynamic IP and have both IP4 & 6 turned on, network is set up as a Wi-Fi router. Main router is the BE85 and I have 3 additional x50.  I have all of the advanced features turned off

First thing I would check is to make sure all the firmware is up to date.

 

  1. Go to http://tplinkdeco.net/ and log in with the same admin password you use on the app 
  2. Once your logged in click on Advanced
  3. Then System
  4. Now click on Firmware upgrade
  5. Scroll down and click on Check for upgrades and install any firmware it might find 

 

Also have you tried to remove the BE85 from your network to see if it corrects the issue? You can remove it from your network simply by pressing the reset button found on the bottom of the BE85

 

Try those steps first and then let us know 

 

Thanks

I've removed the BE85 and I have access to 2.4ghz internet again so the assumption is it's a setting or hardware fault on the BE85 I guess. The firmware is current.

When the BE85 was in the network which port on the router were you using? Did you try all the ports? 

 

Also do you have another device you could install the Deco app on? To test to see if the BE85 is working or not I would install the Deco app on another device and make a new tp link account 

 

Power down all other Deco's and add just the BE85 to the new tp link account and see what happens.
