Model: TL-ER6120  
Hardware Version: V3
Firmware Version: 3.0.2 Build 20200313 Rel.47458

Hello.

 

After I upgraded the TL-ER6120 firmware from 3.0.1 Build 20180724 Rel.80086 to 3.0.2 Build 20200313 Rel.47458

I'm facing now of big issues with AirPrint - Mdns.

 

here are the list of issues :

The printers take a while to appair

The printers list is not complete.

The client make a print to a listed printer and the response is the printer is not connected.

The Printer disappair sudenly from the list.

 

Topology:

Router TL-ER6120

Switch D-Link DGS1210-52P

Omada Software (Linux) 3.2.6 into same subnet

5 EAP-245 V3

2 EAP-225 outdoor V1

1 EAP-330 V1/V2

Only One Vlan/subnet is present into the intranet

 

 

 

Printers:

2 Canon Maxify MB5450  (1 cabled lan & 1 Wlan)

1 OKI MC-573DN (cabled Lan)

1 Brother MFC (cabled Lan)

All Printers are with STATIC IP and reply correctly/fast from ping request without paquet lost

All client device that print with direct IP don't get any error and get they print correctly.

 

 

 

in basic synthesis, the Airprint is now unproductiv and give inconstency response.Users are not able to use Airprint from Apple Devices.

All was worked fine with Airprint till the Firmware Upgrade.

 

 

Tried to resolve with:

reboot the router and the printer

disable all firewall attack Defense

enable IGMP Proxy V2 or V3

Addon Papercut Mobility Print server software into One Lan computer cabled lan   (same issues appaird with this Mdns server broadcasting)

 

 

Seems to have major issues with  Multicasting packet with latest TL-ER6120 Firmware.

 

Questions:

Any other solution to try here ?

Can I downgrade the TL-ER6120 Firmware to his previous version  ?

without a lost configuration ?

 

Any TP-Link advise here ?

Dear @Pascal,

 

Questions:

Any other solution to try here ?

Can I downgrade the TL-ER6120 Firmware to his previous version  ?

without a lost configuration ?

 

Except for the firmware upgrade, did you change any settings in your network?

You can try to downgrade the firmware, please back up the current settings before the downgrade in case the configuration is lost.

If you don't mind, please upload the backup file with the login password so that I can check the settings for you.

@Fae 

I'm sorry to reply so late.

In fact I was not authorized by the confidentiality rules from the client end user to give you those information.

 

I'm surprised that some administrator add removed my post from the community forum.

 

 

may I know why this post was intended as defraying some of the rules of the forum ?
