Internet Wifi Doesn't Work/Disconnects

I'm in an apartment that has cable internet and i use the wifi. The first 2 months, i rarely had any issues besides a few random disconnects where i connect back and its working perfectly.


Few days ago, the electricity went out for close to 2 days. Then once electricity came back, internet worked as well but the thing is the wifi seems to have lot of issues. Some times it would work but then many hours it wouldn't so i have to connect to the internet using my iphone by tethering it as a hot spot. Im also out of the usa at the moment so data here is very expensive so i dont watch youtube or anything like that when tethering the internet.


Is there a way to find out why my internet wifi is behaving like this? The thing is i'm wondering could it be something with my laptop itself because i have had issues with it last few days. I also seen the so called blue screen... i had never seen that before with this laptop ever. Had this happen multiple times as well. Each time it does, i let it load then i restart it to safe mode... then restart it to regular mode.


The thing is i connect to the router by wired internet at the moment so i only use the wifi. However right now im not sure 100 percent if this is an internet problem or it could possibly be my laptop but i lean heavily for it to my cable internet. Is there a way to find out? Also i can connect to the wifi and it will show the 5 bars even when i can't visit sites etc.

Anyone?

I was told this doesn't do anything. I can also tlel you my ip address is not the same as well...

I thought about another thing. My computer has crashed many times within the last few days. It had the blue screen of death many times. So i would just restart it each time. I also have the looking for available socket many times as well.


On my iphone, the wifi seems to be better than on my laptop though but i definitely notice it still is slow just not as slow as laptop. Could the blue screen of death be a factor in this or not? The thing is when i used my data plan on my iphone, the internet was very fast so that means this isn't the issue then?

Okay so internet didn't work most of the day. I had to use my data internet on laptop. However... i then tried to use the wifi on my iphone and it worked without any issue at all. Does that mean this is my laptop then?


Earlier both the wifi didn't work on laptop and my iphone. The thing is i don't really mind about the wifi on iphone since most of the things i do is on laptop. So right now im thinking its something with my laptop now.


What can i do now then to confirm its my laptop?
