TP-LINK Router Connected to CM900 Modem: Orange LED Online, Fast Blinking, No Internet

And how do I connect what should I do?

I wrote - screen ipconfig / all or trying to configure http://192.168.1.1 as long as you have the addressing from the router.

Okay, give you screenshots

Buddy, read my posts back again. I am not interested in your modem, only the tp-link router with which you have problems.

Well, but when I connect the router to the network card, it only shows.

At the moment you are connected to the modem from the provider, at least that's what screen looks like.

I connected as you ordered and somehow managed to install correctly, there is internet, thanks for everything.

So the modem cable in one of the LAN sockets is the same as the computer? This is not the correct connection, you will have a problem anyway

I also connected the modem to the router after that and the internet and wifi work fine.

To the WAN port (blue) in tp-link?

That's what he writes from the tablet.

This last screen is from this configuration? Because somehow I don't think so, but it's okay if it works well. Greetings.

Before installation, I checked ipconfig again and the ip from the router showed up, then I tried to install and it worked, thanks for the help.

Do you not realize that you did not do anything right and only reset the router helped? You did not read with understanding and did not do what was written to you - you had a modem connected to your computer, not a router, and you "configured" the modem and you wanted to log in to the modem. Finally, you showed data from the modem, not the router. Error on error. Besides, no installation of anything is needed for this and other router to work properly! Nothing installs, the router works from the moment it is plugged in. Like a light bulb. A configures only and exclusively via a web browser - entering the data received from the operator in the WAN section and individually, according to his own settings, configures the WIFI section and other sections (depending on the needs).

I wrote this post for readers who are trying to solve their problems, not to offend you. To read and follow advice.

From what I understood, there is internet after connecting the modem to the computer with a cable. If so, do you sometimes need to clone the MAC address of the network card in the router? After this treatment, you will be able to access the Internet via a router.

I do not know how it is in Vectra, it can use MAC address protection. For me, at least in the cable TV from the housing association, in order to be able to divide the Internet through a router, I had to clone the MAC address in the router.
