Slow Download Speed

When downloading new games and updates, Steam takes forever to do so. How do I make downloads faster?

Here are solutions I tried…

1. Ensure no limit to download speed
2. Ensure no throttle to download speed
3. Cleared cache
4. Try different server regions
5. Verify Network Adapters updated in Device Manager
6. Verify Disk Drives updated in Device Manager
7. Set Steam.exe to “High” priority
8. Flush DNS in Command Prompt as Admin
9. Set DNS to 8.8.8.8 and 8.8.4.4 respectively
10. Verified using 5 GHz network band
11. Verified no other high network consuming processes

Other information which may be relevant…
* Router is in the same room as PC (owned by landlord/building owner)
* Internet speed is 400+ mbps for phone but about 3 mbps for PC (not sure why)
* Spouse’s gaming laptop in same room next to my gaming tower but we have different protocols and different download speeds while connected to the same Internet (also not sure why)
