My www.mywifiext.net login is not working? Take an Ethernet cable and tuck it into the internet port of your orbi WIFI extender. The device will now go into the wall outlet of your house to supply electricity. Are you unable to see the power light on your Netgear WIFI extender? Then press the power button situated at the occiput of the WIFI extender. The power LED of your Orbi router will start pulsing and then will become stable. Then check all the slots on your range extender. You will find an internet slot.
