Connect to netgear Genie

Hello everyone,

I just set up the wireless range extender and configured it to extend the wifi of my router (and DHCP server) using another SSID.
But now i can't figure out a way to go back to the netgear genie page on my browser.

The 2 "url", 192.168.1.250 and mywifiext, doesn't work. So I tried setting up my IP address manually but it doesn't work either.

Any idea how to resolve that issue?

Thanks already.
