Hello @RobBR ,

Welcome to our community.

 

After restarting the device, how long did you wait before the severe Ethernet Backhaul failure occurred?

If using one RE705X, can the connection be automatically restored after a restart?

  @Joseph-TP 

If i RE705x lose connection with router it doesnt matter after reboot or i unplug eth cable and plug it back it lost connection to Internet, local networks works. When connection to internet is lost after i reboot RE705x if ethernet cable is plugged in it will never get internet connection. Only walkaround i found is that if i reboot RE705x i unplug eth cable, and when all starts up and internet is available, i plug back eth cable and everything work, till next reboot or unplug. If i reboot router it acts the same. When router is started no internet connection from RE705x. I tried to unplug eth cable without reboot and plug it back, on RE705x, it works as wifi repeater but when i plug back eth cable it stops immediately.

Hello @RobBR ,

Thanks for getting back to us.

 

It seems that your network topology is as follows:

 

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

Archer AXE75 — switch — RE705X)))((( client devices

               └───RE705X

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

 

What model is your switch? Please temporarily remove the switch and test the Ethernet Backhaul again.

 Hello @Joseph-TP 

 

Lower added my topology. It does not matter if there is switch between or not they act the same, i tried. 
Basically if ethernet connection is lost for any reason RE705x don't have access to internet after that.
I tried to disconnect RE705x which is behind switch and left only that is connected directly to router result was the same. If it is working in ethernet backhaul mode and it lost connection after reboot it self or router reboot or unplug ethernet cable, it never gets back internet. After reboot without ethernet cable it connects to router mesh and get internet access, after that i plug back ethernet cable and everything works like charm. Till next interruption.

Hi.

 

I live in EU and will have similar setup soon.

 

AXE75 > wired through gigabit switch or wireless connection to RE705X > wireless connection to RE365 in the garage. Everything over Easymesh to have a seamless connection for my lawn mower close to the garage.

 

The extenders are ordered but still not delivered, so i assume they will be of the later/latest EU-versions.

 

I've found mixed information if this will work or not, but I would like to know if ethernet backhaul is supported now for later EU-model RE705X or if any new software/firmware supporting this is expected to roll out soon?

 

Problem is that my AXE75 is not sending a strong enough signal to reach the garage, so I need a link between (RE705X) and still want to benefit from Easymesh seamless switching between signals.

 

BR.

Hi,

 

Both existing versions of the RE705X have received firmware updates that add support for EasyMesh Ethernet backhaul.

https://www.tp-link.com/en/support/download/re705x/v1/#Firmware

https://www.tp-link.com/en/support/download/re705x/v2/#Firmware

 

The user who started this thread was just reporting that the Ethernet backhaul of the RE705X V1 doesn't work properly after rebooting the router or extender.

Hi.

 

Thank you for the information. Now I'll sleep better, at least until my hardware arrives. 😀
