Problem Accessing MyWifiext.net and http://192.168.1.250/

Additional info to the above post...

Hi folks.

I have a Netgear DGN2200v2 DSL Router and a WN3000RP range extender.

Everything worked fine until I altered the DNS server addresses on the router in order to access Netflix US from the UK.

After that screwed everything up, I put the DNS server addresses back to that of Google > 8.8.8.8 and 8.8.4.4

The range extender is connected to the router and the home network - and all 4 LEDs on the front of the unit are GREEN.

I can connect to the range extender OK but cannot access the internet through it.

I have been onto the extender's web page "MyWiFiExt.net" ONCE and connected the extender to the network - but since then, I cannot access it subsequently. Browser
is Firefox 33.1.1

Typing http://www.mywifiext.net, www.mywifiext.net (no http) or
mywifiext.net (no www) makes no difference, nor does typing in the URL
http://192.168.1.250

I have also tried using both Opera and Chrome. Nothing I enter in my browser's address bar makes any difference.

So, can anyone help?

I have flushed the browser cache and restarted the browser and the wireless laptop is obtaining an IP via DHCP - all to no avail.

Not tried a "factory reset" yet - could this work?

Also not tried a direct connection via Ethernet cable from laptop to extender. Again, could this help?

Thanks in advance,
