Unable To Access Router Page

Last week I got a new router and switched to a different ISP, but for some reason I am unable to get to the router login.

 

I have tried www.routerlogin.net and my Default Gateway

My router is a WNDR4300 or a N750.

Please help. -.-

 

LINK TO TEH TROUBLESHOOTING

If the troubleshooting doesn't work, carefully follow the quick start guides that the isp sent (hopefully sent) if it doesn't work. reset the router

if you hate to call your ISP try the steps below
Steps to try

First of all use a network cable if you aren't already to connect to router (lol) 

if you've got vista or w7. type "network" into the start menu search to find the the network page. if you're lucky your router will be found there ( network discovery must be turned on, it's on by default). Right click the router and click "display device in web browser" or whatever it's called.

When i experimented with my router and turned it into an access point i couldn't find it either at all, but internet connection remained. I had to reset it :/ then i could find it at the standard ip adress of 192.168.0.1

If you haven't got an internet connection at all follow step below. if you do have connection, don't follow it :P

 make sure your network card is set to DHCP (automatic IP adress) Now i assume you're not a complete scrub given the forum we're on. So get to this page through the network and sharing centre.

Network

 Select the IPv4 as the image shows and select properties. Now you should see ip adress mac adress default gateway dns etc etc. if they're not already automatic, change them to automatic but write down any adress that might be there before you do so :>.

If your internet doesn't work, while still at the LAN properties window, press the configure button. Go to the tab "advaced" and find "Link speed & Duples" change it from automatic to 10 mb full duplex or try a different one if that works. If this doesn't change anything. Just turn it to whatever it was to begin with (probably automatic)
