Issues with apps when using router WIFI

  1. Testing packets
    • Open command prompt (cmd)

    • send a ping to any server using the flags -f and -l <size>

       ping google.com.br -f -l 1480
 :: where 1480 is the value in bytes

 :: RESPONSE
 Pinging google.com.br [142.250.79.3] with 1480 bytes of data:
 Packet needs to be fragmented but DF set.
 Packet needs to be fragmented but DF set.
 Packet needs to be fragmented but DF set.
 Packet needs to be fragmented but DF set.
    • make this test decreasing the bytes size until the replies return TTL.
    • Take the value found and add + 28 bytes to it (8 from ICMP packets and 20 used by the IP).
  2. Change the MTU value (maximum transmission unit)
    • Access your router admin panel.
    • Find the location of MTU configuration - in my case was inside port config.
    • Change the value in bytes accordingdly to the result obtained in the test.
::Verify interfaces MTU values
netsh interface ipv4 show subinterfaces
::Change the MTU from the interfaces
netsh interface ipv4 set subinterface <interface_indexmtu=<new_MTU_size> store=persistent

  2. Look for Win8DpiScaling and change it’s value to 1. 3.Create a DWORD32 named LogPixels (if it doesn’t already exists) and set the value to DECIMAL=120 DEFAULT DECIMAL=125.

Method 3: Individual setting for apps

  1. Right click on the executable file from the application being blurred and go to properties.
  2. Navigate to tab Compability.
  3. In the Settings section, choose: Change high DPI settings.

Run the System File Checker tool (SFC.exe)

To do this, follow these steps:

Open an elevated command prompt. To do this, do the following as your appropriate:

If you are running Windows 10, Windows 8.1 or Windows 8, first run the inbox Deployment Image Servicing and Management (DISM) tool prior to running the System File Checker. (If you are running Windows 7 or Windows Vista, skip to Step 3).

Type the following command, and then press Enter. It may take several minutes for the command operation to be completed.

DISM.exe /Online /Cleanup-image /Restorehealth

Important: When you run this command, DISM uses Windows Update to provide the files that are required to fix corruptions. However, if your Windows Update client is already broken, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. To do this, run the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess

Note: Replace the C:\RepairSource\Windows placeholder with the location of your repair source. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image.

At the command prompt, type the following command, and then press ENTER:

sfc /scannow
