How to set up Internet access if it says "no Internet access"?

Question

Computer networks

provider - viltel
router - tp-link tl-wr741nd
lan plugged into the router, from it another lan to the computer
History: forgot the password from the router, reset to the factory button on the router, network without access to net. I remembered then that on the site you need to configure the router. I went to the site / quick setup, chose the ip speaker and did it to the end, the router rebooted. still no internet access. I tried to directly connect lan to my computer - similarly. I went into network connections, checked there, as it should be - get ip automatically. called those. support, they said that everything is fine in network connections, but let's try to enter ip ourselves, entered it - in vain.
What else can be done to have access to the Internet?

Answer 1

First you need to log into the router. To do this, go to the web interface of the router by clicking here and enter the default username and password.
Next we need a quick setup item. There, of course, further and try, follow his instructions to configure again
