Try one more time having Username:admin Password:adminorUsername:admin Password:rootorUsername:root Password:adminIf none work, there should be a reset button on the back up the router. That should reset username and password to deafult.(One above or the one from post from before.)
Try going to your control panel, and then clicking on "Windows Firewall". After that, click on the bar at the top that says "Exceptions", next, you should see a list. Check the tick box on everything that says "Blockland"
None of them worked...:/
