Hi Farshid99,
Welcome to Microsoft Community.
I'm Hahn and I'm here to help you with your concern.
The number after your network name in Windows represents an incremental count of how many times your computer has identified and connected to a network with the same name (SSID). This usually happens when the network profile is saved multiple times, possibly due to different configurations, changes in network hardware, or connecting to networks with the same name but different credentials or locations.
For example, if your network name is "POCO F5" and you see "POCO F5 53", it indicates that Windows has saved multiple profiles for networks named "POCO F5".
Why This Happens:
- Duplicate Network Profiles: Every time Windows detects a network with the same SSID but different settings, it creates a new profile.
- Changes in Network Configuration: Changes in your network settings, such as a different router or new security settings, might cause Windows to create a new profile.
- Reconnecting After Network Issues: Sometimes after network troubleshooting or resetting your router, Windows may create a new profile.
Method 1: Using Settings App
- Open the Settings app.
- Go to Network & Internet.
- Select Wi-Fi from the sidebar.
- Click on Manage known networks.
- You will see a list of all the saved networks. Find the duplicate or unwanted profiles and click Forget.
Method 2: Using Command Prompt
- Open Command Prompt as Administrator.
- Type the following command to show all saved wireless profiles:
netsh wlan show profiles
- Note down the names of the profiles you want to delete.
- Delete the unwanted profiles by using the following command:
netsh wlan delete profile name="ProfileName"
Replace "ProfileName" with the name of the profile you want to delete.
Preventing Future Issues:
- Ensure that your router's SSID and settings are consistent.
- Avoid creating multiple network profiles for the same SSID.
By managing your network profiles, you can prevent Windows from adding incremental numbers to your network name.
Your Sincerely
