Internet suddenly not working?

I was on my laptop, happily playing gmod. I decide that I'm bored and decide to go play some Minecraft. This is where I first noticed some issues with my internet. Minecraft would not let me update to version 1.7.4, and so I just restarted it, it started downloading but It was very slow. I thought that maybe because of Australia's 500kpbs internet speed it was just slow because it was slow, but it was happening with facebook aswell; I was not able to view any photos or videos and profile pictures had the red cross in the box. I thought that I'd probably try to see if any other websites were doing the same thing, so I went onto google, searched up something random, went onto the site and it just displayed the 'ERR_CONNECTION_FAILED' message when I went onto the website. This was not for the certain website only, I tried other searches and still the same result. I tried going back to facebook and just displayed the 'ERR_CONNECTION_FAILED' message and wouldnt let me onto the site. I restarted my internet browser, and this time it wouldnt even let me connect to Google itself. It doesn't even display the internet image. I attempted changing my DNS to googles basic dns which is 8.8.8.8, and restarted my internet but still the same result in internet search. I'm currently running scans on Malwarebytes and windows defender but if there's anything that I should do please tell me straight away.

Am i ready for the nether? Minecraft?

I'm wondering if I'm ready to go through the nether. Or if I need more. My goal is to get a blaze rod and Scotland and nether wart.

Should I change my YouTube content?

I have been doing YouTube For a year now and I only have 37 subscribers. I use an elgato and I put as much effort as I can in each video. I go trolling/glitches. I have been thinking of removing all my videos and doing daily minecraft videos. What do you think I should do?
