Wifi connection cutting off every 20 minutes

My internet is turning itself off about every 20 minutes, and I have to go to the network and sharing center and run troubleshoot wifi connection 3 a several times before it goes back to normal.

What I've checked:

• The internet works without fail on my phone. The problem is surely on this device.
  
• The wifi connection 3 thing on network and sharing center is the thing that always goes offline (has a red cross next to it)
  
• My intelligence... I'm pretty bad at computing so please explain this in steps.
  

I'd really appreciate it if someone could tell me how to stop this inconvenience from occurring every 10-20 minutes, its really frustrating. I need to answer questions and get more reputation on writers SE .

Thanks. By the way, I ran a scan. Its not a virus or malware, whatever else it could be.

How to get damn DISM to work?

Thx guys, I'll compress this data into a blog post. For all the so called guides I've read, not a single one mentioned it has to be WIM file (some listed even ESD which clearly doesn't work) or that certain ISO images don't work with DISM.

After I've done DISM thingie, SFC also managed to repair stuff. Which is what I've needed here.
