Windows 10: 1 Wifi bar on every network on PC, but full bars on mobile phone

I recently got an OLED monitor, and everything was working fine until my wifi went from 4 —> 1 bar of wifi. Now, the speed is extremely slow and I can’t load anything. I’ve tried restarting the router, resetting internet options, basically everything—even moving the router closer. I don’t know what I can do.

Only 1 WiFi network


My network list on my phone:

Error "The wifi network .... didn't respond" when using PC as mobile hotspot

Original title:- Use my PC as a mobile hotspot

When my PC has a cellular data connection, I want to turn it into a mobile hotspot to share my connection with other devices.

To do this I follow these steps.

• 
  Select the Start button, then select Settings > Network & Internet
  > Mobile hotspot.
  
• 
  Select Edit, enter a new network name and password, and then select
  Save.
  
• 
  Turn on the control under Mobile hotspot to share your cellular data connection.
  

After that I enter my Password to my nokia lumia 925 phone and try to connect to my new wifi network.

But it says "The wifi network .... didn't respond"

• I enter my password correctly.
• Turn of my wifi in pc
  

 

Sound Bar Needed

That one has rear speakers also. I swear that bar alone sounded like it was all around me.

FYI I aint arguing. I'm just trying to educate myself. What would you suggest?
