Deco M9 Guest network not working after update to 1.6.1

Deco M9 Guest network not working after update to 1.6.1
Deco M9 Guest network not working after update to 1.6.1
2023-07-31 14:08:53
Model: Deco M9 Plus  
Hardware Version: V2
Firmware Version: 1.6.1

My WiFi guest network will no longer work after updating to 1.6.1.

 

The SSID appears and is being broadcasted but after connecting it says "No internet, secured"

 

This happens on any Windows device. Android devices do not connect either and are never served an IP address 

 

There is a switch connected to one of the main router ports (but not in between the modem and router), and another switch connected to one of the access points, which gives Internet to another access point elsewhere in the house.

 

Any help would be greatly appreciated.

Issue is occurring only when near a specific access point.

 

All access points are wired via ethernet, expect for one that is out of range from me.

 

The one closest to me is the one having issues.

 

All switches are unmanaged.

  @Ouremcee 

Hi, Thanks for the feedback.

I think your issue might be like this:

https://community.tp-link.com/en/home/forum/topic/616724

Can I have the model numbers of the two network switches?

Did the network topology remain unchanged before and after the firmware upgrade?

 

Wait for your reply.

Best regards.

  @David-TP Please see the updated diagram with model numbers.

 

Also below are the network switches and model numbers of those switches:

 

  • TP-Link TL-SG105
  • NETGEAR GS308v2

 

The network topology did not change, and I have only run the firmware upgrade.

  @Ouremcee 

Hi, Thanks for the update.

I see NETGEAR GS308 is an unmanaged switch, which is almost the same as TL-SG105.

But I happen to see there is a similar model NETGEAR GS308E which is an easy smart switch and supports VLAN Configuration.

Could you please confirm whether the switch is NETGEAR GS308 or NETGEAR GS308E?

 

If it is the second one with "E", I think there still needs addtional VLAN Configurations on the NETGEAR GS308E to make the guest network work properly on the third satellite Deco M9 plus:How to extend guest network when there is a switch between Decos

Or Could you please help me run a simple test:

switch the location of these two satellite M9 plus units to see whether the issue follows the same unit or the same switch.

 

Wait for your reply.

Best regards.

@David-TP Here is the model number

 

6d49ad5cc61f4313975421c32da5756b

 

I cannot move the locations of the Deco's at the moment but can try to do so later.
