I have purchase a 3-pack Deco E4 recently and the hardware version is V2, it is quite difficult to reset them and sometimes took me over a few minutes to keep on pressing the reset button for it to reset eventually.  I have tried holding the button from 1 second to over 10 seconds, but still cannot find any reliable way to reset the Deco.  I wonder whether this is normal for this product or my units are defective.  Also does the Deco E4 still support entering the setup page through entering tplinkwifi.net in the web browser?  The usual TPLink default password, admin, is not able to log in and there is no password information in the manual.  The tplinkwifi.net page only allows 10 password retries and what'll happen after it all fail, will it cause the Deco to shutdown and prevent all further access?   Does TPlink only allow using the Deco APP to set up the units and obsolete the tplinkwifi.net approach?

Thanks,
