I have been using a TP-Link Extender (EAP120) for some years now and for the past months there have been incidents of network time delay when there should not be. So I suspected changing the Extender network name might solve this (I was using the same name for router and Extender). However I was not able to access my Extender configuration page.
I reset the Extender, I used the Windows command prompt to find default gateway and ip adress, but I am not able to access the configuration page with either ethernet or wi-fi. I tried what guidelines I could find online, but none seems to work.
The Extender is wired by ethernet cable to my router so I have Internet access via wi-fi in my computer, but since resetting I am unable to assign a password to protect my network, which is really important to me.
Thank you for your assistance!
