Hello there!

I'm having for several days a sudden problem - I can not run lots of websites on Windows 10 without a reason. After plugging my smartphone to a computer I have changed in Windows to its internet and then I could open them, but problem still occurs on my main internet that computer is plugged to by RJ-45 port.

I thought it can be a problem with Windows so I downloaded Ubuntu and made a live version on pendrive. The same thing is happening on completely different system but same PC.

I took ethernet cable and plugged it into different device (laptop) and it worked normally.

Do you know what can it be? First time I reached this kind of ridiculous problem I can not figure out what can cause it.

I have forgotten to mention that I can not also log into Origin and Steam on main internet on PC.

Thanks in advance for response.

these are some of the things that effect web access, so check them out for all your devices.

router/modem firewall
PC firewall
security programs, eg: anti-virus software, malwarebytes program
an ad-blocker browser add-on
modified HOSTS file
malware infection

because your issue is happening on different systems, it would indicate the problem is with your internet hardware, so look on your modem/router for a blacklist or firewall or MAC address filtering that could be denying you access.
