Slow Wi-Fi access with Pulse Secure VPN Client

This problem affects both network file transfer and internet access speeds but most particularly, the download side, when Pulse Secure VPN client is running.

I have summarised one of the two solutions (simpler one, less technical) that can be found here: https://kb.pulsesecure.net/articles/Pulse_Secure_Article/KB43833
and attributed to Lokesh T K.


  • Although disputed by some(vendors and users), the most probable cause in lite of our experience, relates to either or both the Windows 10 1809 and the 1903 updates and how they may have affected specific wireless adapter driver files

  1. Press the Windows Start key and type 'Control Panelselect Network and Sharing Centre and then select Change Adapter Settings to open Network Connections
  2. Locate and right-click the Wireless network adapter, select Properties
  3. From the list, uncheck the checkbox for Juniper Network Service 

  4. Start Pulse Secure and connect as per usual
  5. Returning to Network Connections, select Pulse Secure virtual adapter

  6. Right-click the adapter and select Properties
  7. From the list, uncheck the checkbox for Juniper Network Service
