GL-MT3000 cannot access admin

Trying to set up this router following instructions, which do not reflect what happens after each action, but I have tried chrome to access the admin panel and set up the modem. The modem is connected by wifi and cable so should be no problem but of course there is a problem. This is almost like dealing with a Microsoft product.

Any help would be greatly appreciated. Thank you in advance.

What exactly did you do and what step did not work?
