Microsoft says computers running Qualcomm wireless network adapters may suffer sporadic loss of Wi-Fi after Windows 10 May 2019 has been installed as a result of out – of-date network drivers.
Windows users wishing to update version 1903 of Windows 10 may download and use the current WLAN driver available on their device manufacturer’s (OEM) drivers to install the latest driver version of their Qualcomm Wi-Fi network card.
Block added to prevent users from updating the computers affected
Microsoft also says in the support document that an update block was put in place to block the Windows 10 May 2019 Update from being offered until a compatible Wi-Fi driver is installed to prevent any issues arising from incompatible out – of-date Qualcomm drivers.
“We’ve used this Qualcomm driver to protect your upgrades from Windows 10 releases, version 1903, until the updated driver is installed,” says Microsoft.
In addition, Redmond recommends to affected windows users that they do not manually “use the Update Now button or the Media Creation Tool” to update and update their Qualcomm Wi-Fi drivers system.
This prevents intermittent network connectivity loss caused by the old network drivers and enables a stable network connection to be provided by affected Windows machines until the latest Windows 10 update is applied.
Alerts for insecure wireless networks
Users who have upgraded their Windows 10 version of 1903 computers are alerted in this news about insecure Wi-Fi networks using the older Temporary Key Integrity Protocol (TKIP) or Wired Equivalent Privacy (WEP).
These two safety protocols have faults that allow potential attackers to decrypt traffic and not as safe as WPA2 or WPA3.
According to Microsoft support website, in the future it is recommended that any connection to a Wi-Fi network with these ancient cipher is not permitted, and that Wi-Fi routers should be updated to use WPA2 or WPA3 available AES-cipher. Utiliers should disconnect the TKIP or WEP-secured Wi-Fi networks if they are alerted, connect and install a secure WPA2 or WPA3 connection to a wireless network as well as upgrade their Wi-Fi network.
