Help internet connection

[desvest]

Good evening, I am telling you about a problem that started today. The computer suddenly lost the connection and every time I want to enter a website, it sends me to the IP address of a Huawei router 192.168.1.8, when I have a Sagecomm that is obviously on the 192.168.1.1. The gateways are on 192.168.1.1 and obviously I can not navigate with any browser, pardon the redundancy and I can only access with Tor, but according to Windows, I do not have access to the web. I restart and for a few minutes I have connection, that's why I installed Malwarebyts, but there is nothing wrong. Does anyone have an idea of how it could be solved?

Hello,

Do you connect via cable or WiFi?
Have you tried restarting the router?
Have you tried resetting the network configuration? (Disable and enable network card, CMD > ipconfig /renew, etc)
Have you tried booting into Safe Mode with Networking?

Best regards

Hello @sylver, thanks for responding. I only have my computer wired, I don't have a WiFi antenna (the problem appeared suddenly), when I restart the computer it works fine for a few minutes and then it starts with the errors.
I tried restarting the router too and then it does the same thing to me.
I disabled the card and re-enabled it and nothing, but I haven't tried the renew, I'll keep that in mind.
I haven't done the last query, but I'll see if I can do it then to see if it works.
I leave some images that the browsers also throw up:

@desvest The thing with the Youtube certificate smells like a scam. Set up a manual DNS in Windows, restart the browser and try again. IBM's DNS (9.9.9.9) is a good option.

I know it sounds strange, but the simplest solutions often get overlooked. Have you correctly set the date and time on Windows? If it's not set correctly, browsers will throw certificate errors.

Thanks cobito and Yorus. The YouTube thing is because I was entering that page at random. As of today, the problem has not happened again. The date and time are correct. The problem was solved by itself, which leaves me more uneasy jajaja

Good afternoon everyone, I have finally discovered what the problem is. I share my connection with a neighbor, and we run an ethernet cable through the balconies. He has a Huawei router in his apartment, which is why he tries to access my settings. I don't know why this happens, even though I have already assigned myself a static IP. The router that my neighbor has apparently does not have bridge mode, is there a solution?

[Sylver]

@desvest Although any router can act as a switch, some are stubborn enough to want to control the entire connection above the main router, no matter how hard you try to configure them.

Ideally, your neighbor should use another type of neutral router, or a switch if they only use cable.

Best regards

Vale @sylver, I'll tell him to make an investment. It just so happens that he uses that router to get WiFi in his house. We'll have to put in a wireless switch or something like that. What makes me angry is that this didn't happen before, overnight it started to go to hell... Thanks for the response!

[Sylver]

@desvest De nada. I assumed you were using it over WiFi, so another router, even if it was from another company before, is also something you can try.
The old ones usually work very well and don't cause any problems as they are basic, although they usually have the limitation of ports at 100 Mbps.
