Windows 10: Home network - PCs unable to connect after the Win10 2004 update

I have a simple home network for my 2 PCs connected by CAT6 cable to the same router. File share for some folders is enabled and access to this has been working perfectly.

... Until the Version 2004 update was done last week on both PCs.

Now I get an error - it cant connect to that drive. None of my shortcuts work.
If I go to File Explorer and type the ip address it brings up a "Windows Security - Enter network credentials" box. No idea what these are - didnt think I had initially setup credentials.


Not even sure where to start troubleshooting.

I pinged each PC in a command prompt which works fine.

Any advice on where to start looking for the issue? What could this upgrade have done?

:)

 

Losing network connection

Hello Dear, if you have a laptop or a PC with a wireless network adapter, you can see a list of available wireless networks and then connect to one of those networks. The wireless networks will only appear if your PC has a wireless network adapter installed, the adapter is turned on, and the wireless access point is in range.

1. Click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections.

2. In the left pane, under Network Tasks, click View available wireless networks.
In case, If you don't see the network you want to connect to, click Refresh network list. If you see the network but the signal is weak, move the PC closer to the wireless router.

3. Click the network you want to connect to, and then click Connect.

4. If you're connecting to a secure network, type the security key, and then click OK.

I Hope you solve out your query soon.

 

Network Connectivity Issue

Hi,

The problem you've encountered with your network connection is most likely caused by an outdated network driver since this appeared after the recent update. We suggest updating the driver for your network adapter. Please follow the steps below:

• Right-click Windows key and click Device Manager.
• Expand the Network adapters category.
• Right-click the one that says Ethernet Connection, then click
  Update Driver.
• Select Search automatically for updated driver software.
• If Windows is unable to find a new driver for your network adapter, try checking its manufacturer's website.

If the above steps don't work, try reinstalling the driver. Here's how:

• Open Device Manager, right-click the name your network adapter, then select
  Uninstall.
• Restart your PC and Windows will attempt to reinstall the driver.
  

Update us with the result.

Regards.

 

2004 update and metered network connection

Thanks for the response. I knew the last on which you have mentioned. I am having wumt 2016 files. but did not use it as win update was showing the size for metered connection. As now it is not there, I have to use wumt.
I have already win10 2004 19041.329. But unfortunately wumt is showing many of that not shown by Win update. Further it shows 1903 update also.as below.
