WiFi speed drops to ZERO

The WiFi speed suddenly drops to ZERO. It fluctuates between the maximum speed and zero, and then finally sticks to ZERO. I have tried almost everything like troubleshooting, Re-installing the WiFi driver, Disabling & Enabling the WiFi driver, etc. I have
also tried to connect the same network with the Ethernet and it worked fine. Is this the software issue or some hardware issue?

 

WiFi LAN speed drops to zero for 2-4 seconds every 20-60 seconds. Effectively killing the connection

My machine specs:

• HP Envy 15'' Laptop
  
• Windows 10
  
• 8GB Ram, Inte Core i7-4700MQ 2.40GHz, 64 bit system
  
• WiFi adapter: Ralink RT3290 802.11bgn
  

Issue

My laptop's WiFi LAN download and upload speeds drop to zero frequently(every 20-60 seconds) for about 2-4 seconds and then they go back up again. This is not a big issue when downloading stuff or watching series online but it is so incredibly frustrating when skyping, playing online videogames etc. This is not specific to Windows 10 as it begun when I was running windows 7 or 8, can't remember.

What I've tried:

• Other computers on the same WiFi: No other of my machines have this
  problem and neither do any of my 5 flatmates.
  
• Other WiFi networks: This does indeed happen when connected to any other
  WiFi routers (so my laptop is the problem)
  
• Uninstalling the WiFi Driver and installing again. Tried thrice, did
  not solve the issue (maybe I did it wrong?)
  
• I even used that Windows 8 option to restore the laptop to factory
  settings while keeping only files, did not work.
  
• Lots of other random things that did not work either.
  

I need to be able to Skype but as of now it's such a painful experience every time. Normally, I can fix most of the problems on my PC by myself but this one will make me go mad.

 

Case fan speed drops to zero for just 1 SECOND then returns to normal

Here's a weird one that seems to happen at random times, maybe twice a day or so:

According to my Argus Monitor fan monitoring/control software, my computer's front case fan (PWM) is spinning along at a proper speed of about 340 rpm. Then Argus Monitor reports that fan rpm suddenly drops to ZERO in just ONE SECOND, and then fan speed is back to 340 rpm in the very next second. I caught this behavior in the act and looked at the fan, but the fan was spinning normally (I didn't see it slow down, let alone drop to zero). Besides, how can a spinning fan slow down to zero and spin back up to normal in just two seconds anyway?)

Could this be a problem with the fan, the motherboard, Windows 10, or Argus Monitor?
