Hi there, 

I have just installed a EB810v EB22000 router from the service provider in a bundle contract. The technician set up the wifi network for me very quickly and only asked me to key in my preferred SSID and password in his tablet using the Aginet app (i think). He did not show me how to go into the device management page on how to modify or manage the device.

I am thinking of adding in a wifi range extender RE505X to the EB810v. I am not sure if this require me to login to the device configuration page. I have already set up an account but when I am prompted to key in the device password to access the EB810v page, I tried the default password indicated on the device label at the bottom, but it prompted me incorrect password. 

i have tried to contact my service provider to check if the technician did change the device password when setting it up for me, they informed me they are unable to do so, and directed me to check with TP Link instead.

My question is: do I need to login to the EB810v device configuration page in order to add in a range extender? Or don't need to? I am trying to avoid resetting the network as I am not quite sure how to set it up on my own.

Please advise me. Thank you.
