Model: TL-SG108E
Hardware Version: V4
Firmware Version: 20180730

Just buyed the TL-SG108E and installed the 'management' utility. Switch was perfectly found.

I saw on the support pages there was a newer firmware (20181130) and I want to install it.

I have started the upgrade with that downloaded file and about half way 'Some error occured' was the message.

 

After that error the 'Unmanaged Pro configuration utility ' was not be able to find the switch anymore.

 

I want to reset the switch, but how should I do that? (I have seen the reset hole, but 'pinning this' gives no result

 

Thanks for thinking with me

@Interspeed 

 

How to hard reset it: With the switch powered on, press this button for five seconds or above to reset the software setting back to factory default setting.

 

Then connect the computer which installed the configuration utility to the switch only and setup static IP for the computer as the instruction below:

https://www.tp-link.com/support/faq/14/ 

 

After that, please verify whether the utility can detect the switch; if not, please ping the gateway of the switch and show us the results.

Note: The gateway is 192.168.0.1 by default.

 

Good day.

Hi,

 

I have the very same issue - received my switch today, wanted to upgrade the FW to Version TL-SG108Ev4_en_1.0.0_[20181120-rel40749]_up - the Unmanaged Pro Configuration Tool showed an error and the Tool is not showing anything anymore.

 

During the upgrade the SG108E (V4) was connected to an SG105E (V1). The SG105E is still showing up in the Config Tool. Lights are still on on the SG108E and even Network seems to be up. 

 

The Gateway 192.168.0.1 could be reached (ping is showing results), but this might be influenced by the SG105E.

 

I tried to connect the SG108E directly to my PC and to change my subnet to 192.168.0.x - but then the switch did not show up in the Config tool as well.

 

The Reset Button is doing nothing btw...at least nothing, I can see. I've pressed it for far more than 5 Seconds, turned off power, pushed the button before turning power on again....all does not change the behaviour.

 

What else could be done to revive the Switch?

Or is it directly bricked by the standard update procedure?

 

Cheers

I've tried the direct connection now again - Config Tool does show nothing, Default Gateway of switch is pingeable...

 

What next?

Not sure it matters, but subnet mask should be 255.255.255.0

As far as I know, this Subnet mask just says, that my computer is looking into 192.168.*.* If I would set it to 255.255.255.0 it would look into 192.168.0.*
