I have a Tp-Link Wr741ND and my only problem is that I can not configure it correctly, I explain, after connecting the network cable to the LAN port of my tp link, being connected to my computer, I enter with the default ip: 192.168.0.1 This is where the problem comes from. since the username and password is: admin. After placing this automatically redirected to the router page but it remains white with certain divisions in the screen but I can not press any option, leave the boxes of the options but blank. the router of rest serves perfectly since I can place the direct cable of the modem and emit wiifi but without password, I want to configure it to place a password but it does not let me do it. please help
