WiFi dropping connection every few minutes

Hello,

Your issue might be related to a variety of factors. Let's try to troubleshoot it step-by-step:

1. **Reset Your Network:**
- Open the 'Settings' application (or press Windows Key+I)
- Navigate to 'Network & Internet' > 'Status'
- Scroll down and click on 'Network Reset'
This will reinstall your network adapters and set your networking components back to their default settings. Your computer will restart after this process.

2. **Update Network Adapter Drivers:**
- Right-click the Windows key and select 'Device Manager'
- expand 'Network adapters'
- right-click on the wifi adapter and select 'Update driver'
If the problem persists after this, try downloading the latest drivers from the manufacturer's website.

3. **Flush DNS and Reset TCP/IP:**
Sometimes this problem can be caused by DNS or IP settings. Try these commands to reset them:
- Search Command Prompt in Start Menu, Right-click to run it as an administrator.
- Type the following commands one by one and press Enter after each:
`ipconfig /release`
`ipconfig /flushdns`
`ipconfig /renew`
`netsh int ip set dns`
`netsh winsock reset`
- Restart your computer

4. **Configure your wireless adapter settings:**
- Open the 'Settings' app
- Navigate to 'Network & Internet' > 'WiFi' > 'Hardware properties'
- Write down the name and manufacturer of your adapter
- Open the 'Power Options' from Control Panel
- Find your power plan and click on 'Change plan settings'
- Click on 'Change advanced power settings'
- Locate your wireless adapter in the list and set it to 'Maximum Performance'

5. **Change the WiFi channel:**
If you have a lot of devices connected to the same WiFi channel, it can cause problems with your connection. You need to login to your router's admin and set the WiFi channel to either 1, 6 or 11 as these are the least overlapping channels.
Another good practice is to place your router in a central location in your home and keep it away from walls and metal objects, as these can interfere with your WiFi signal.

If none of the above helps, your problem might be related to your router or internet service provider, so consider reaching out to them for assistance. Let us know if the issue remains, we are here to help.

Possible Underlying Issues:​

1. Interference or Signal Issues:
   • Crowded WiFi Band: If you're on a busy 2.4 GHz frequency in a neighborhood with other routers, interference could frequently disrupt your connection.
   • Distance or Obstacles: Are you far from your router, or are there lots of walls/metal objects hindering the signal?
2. Router Problems:
   • Overheating or Overloading: If your router is old or overworked, it might be struggling to maintain stable connections.
   • Firmware Issues: Outdated router firmware can cause odd connectivity problems.
3. Device-Specific Issue:
   • Your WiFi adapter or network interface card (NIC) may be faulty, have outdated drivers, or be configured incorrectly.
4. DHCP or IP Lease Expiration:
   • If your DHCP server (on the router) is reassigning IP addresses, it can cause frequent disruptions.
5. ISP Service Drops:
   • As a last possibility, the actual problem might reside in your internet service provider having intermittent disruptions.

Advanced Steps to Fix:​

1. Manually Set a Static IP:
   • Sometimes, DHCP reassignments can lead to your device being kicked off the network. Assigning a static IP to your computer can prevent this.
   • Go to your WiFi settings > Adapter Options > Right-click your network > Properties > IPv4 > Set your IP manually (use something like 192.168.1.150 with a gateway of 192.168.1.1 if that matches your router's IP range).
2. Adjust Router Channel Width & Band Selection:
   • In your router’s admin dashboard:
     • Select 20 or 40 MHz for the 2.4 GHz band.
     • If using 5 GHz, try different channel settings or bandwidth limits to see if stability improves.
3. Perform a Factory Reset of Your Router:
   • If the router has retained corrupted settings, performing a reset and reconfiguring it might help eliminate glitches.
4. Replace or Upgrade Router/Adapter:
   • If the router is more than 4-5 years old and you're still facing issues despite attempts to fix it, consider upgrading to a dual-band or tri-band model.
   • Similarly, test your computer with a different external USB WiFi adapter to see if the built-in NIC is causing problems.
5. Run a Ping Test:
   • Open Command Prompt and type: ping -t 8.8.8.8 to monitor connection quality over time. If there are widespread packet losses, this indicates instability either from the router, your connection to it, or the ISP.

As a Temporary Measure:​

• Go to Device Manager > Network Adapters > Right-click your WiFi adapter > Properties > Power Management tab > Uncheck "Allow the computer to turn off this device to save power."
