Model: Archer AX55  
Hardware Version: V1
Firmware Version: 1.3.5

I foolishly accepted an AX55 firmware update yesterday to v1.3.5, and most of my RE200's went offline.

 

I have 6 RE200's, 5* V5 Easymesh, and 1* V3 Onemesh.

 

No amount of rebooting, resetting or reconnecting brought them back

The AX55 also became quite laggy.

 

I've rolled back to v1.3.3 and evertything is working again.

Hello@wrighar ,

Thank you for contacting our community.

Could you provide us with a backup file and system log to reproduce this problem? This is a very strange situation, and we hope to locate the problem.

 

Please refer to the FAQs below to collect system logs and backup files of the router:

How to view and save System Log of TP-Link wireless router

How to create and restore from a backup file on your TP-Link Router

Then email the logs and backup files to support.forum@tp-link.com, attaching [Forum ID 833830] and details, and we will have a dedicated person to assist in analysis and follow-up.

Hi @Adrian94 ,

Have you downgrade the firmware for a try?

@Joseph-TP  Yes, I downgrade firmware from 1.3.5 to 1.3.3 and TetherApp and works fine with this router ..

Hi @Adrian94 ,

Thanks for getting back to me.

 

May I know if your network topology diagram is as follows:

ISP modem—AX55 )))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

 

Does the Tether App disconnection occur when you are locally connected to the AX55 WiFi or when the Tether App is remotely accessing the router? Or does it happen regardless of whether it is connected to the AX55 WiFi or not?

Confirming this information is to help us reproduce your scenario and locate the problem.

@Joseph-TP  Connection: Fiber -> ONT Device (Converter from fiber to ethernet) -> Ethernet RJ45 -> Archer AX55 (with public IP on WAN and PPPoE)

Problem is when I use TetherApp with the same wi-fi (network). When I use mobile transmission there works fine.. I select "Cloud Device", not "Local Device"

 

Also I have more routers in app, not mash e.g. :)

Hello @Adrian94 ,

Thank you for your reply.

 

Please check the firmware of the three routers. Logically, the two online units should be using version 1.3.5.

If so, please make sure the firmware of the offline units is consistent. Then restart the entire network system and check whether all devices are back online.

  @Joseph-TP Sorry but you didn't read my message. I have routers AX55 in different houses, not mash. They are independent of each other. In fact, they even have different internet providers.

In new firmware 1.3.5 for AX55, TP-Link broke management in TetherApp. 

I'm able to send more details for analysis (login attempts, IP address, router MAC) and I would expect a fix.

Unfortunately, I joined this thread instead of creating a new one to draw attention to the problem with firmware 1.3.5

Hi @Adrian94 ,

Thanks for your reply.

 

So that these three routers are independent, is it true that the network disconnection problem occurred after updating to 1.3.5?
Is it a specific AX55 unit that has the disconnection problem? If so, please check the firmware version now. 

If all three routers experience a network disconnection, please provide the network topology diagram of AX55.

For example,ISP modem—router)))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

 

Please refer to the FAQs below to collect system logs and backup files of the router:

How to view and save System Log of TP-Link wireless router

How to create and restore from a backup file on your TP-Link Router

 

Then email the logs and backup files to support.forum@tp-link.com, attaching [Forum ID 833830] and details, and we will have a dedicated person to assist in analysis and follow-up.
