Model: TL-SG108PE  
Hardware Version: V5
Firmware Version: 1.0.0 Build 20220930

Hi, I just bought five TL-SG108PE, they were all working fine with factory firmware, but as a new one was released a decide do upgrade one switch to test. After that, when I enable 802.1Q VLAN, the traffic on management vlan id 1 become slow, and some devices can't ping and open on webui

 

I have 14 TL-SG108PE on the network, when the device with latest firware is on without 802.1Q VLAN, a use nmap to scan a devices and a can see the 14 devices, but after activate, the list of devices returned by nmap is random and always missing devices.

 

I need a firmware fix for this problem or a way to roll back to factory firmware on this device

 

Extra info:

802.1Q VLAN is enable on all 14 devices with different hardware version, and all working fine, except the the v5 with latest firware

 

Lateste Firrmware:

 

1.0.0 Build 20220930

 

Factory Firmware:

 

1.0.0 Build 20220531

As a first step - did you reset to factory defaults on new firmware to see if that helps?

Yes, I did several times, using key button and ui. After reset as the vlan is off the device works and no problem happen. After set vlan again the problem start to happen
