Windows 10: Can't get two ethernet networked computers to communicate

I'm trying to set up a home network consisting of a desktop and a laptop, both connected to a wifi router via ethernet cables. I have the router's wifi shut OFF.

The desktop shows the laptop under Network, but when I try to access it I get a message
"Windows cannot access \\Laptop. You do not have permission to access \\Laptop. Contact your network administrator to request access." (I am the "network administrator"). I have set drives and folders on the laptop to be Shared by Everyone.

The laptop shows the desktop under Network, but when I try to access it I get a message "Enter network credentials. Enter your credentials to connect to Desktop." and asks for a password. I didn't think I needed a password to connect, but in any case I don't know what it is. (I've tried the password to the router, but that didn't work.)

How can I proceed with both problems?

Windows v. 1909

Network Communication problem with multiple computers

Hi Jay,

Thank you for responding.

I suggest you to try the below troubleshooting steps and check if it helps.

Method 1: Network discovery might be blocking you from seeing other computers and devices on the network. Check if the Network discovery is turned on. If the network discovery setting on your computer is set to off, you
won't see other computers and devices on the network.

Steps to Turn on network discovery.

• Press Windows key, type sharing and click on
  Manage advanced sharing settings.
• Under Private, Network discovery, check mark the option
  Turn on network discovery.
• Try the same on all the computers connected to the network.

Method 2: If the issue still persists, run
HomeGroup troubleshooter and check.

HomeGroup troubleshooter finds and fix problems with viewing computers or shared folders in a HomeGroup.

• Press Windows key, type troubleshooting
  and select it.
• Click on View all in the left pane and click on
  HomeGroup.
• Follow the on-screen instructions.

Hope it helps. Kindly update the status of this issue for further assistance.

 

Ethernet Light Orange/ "Local Area Network" Not in Network List

Last night I noticed my ethernet light on the back of my computer was orange. I did some research to find the reason. Some websites said it was an increased connection speed. Others said a problem with the connection.
The local area network is no longer in the list of network connections and the other computer in my house has a green light on the ethernet port.
I've used all the cmd.exe ipconfig steps suggested by websites. Flush dns, reset dns, etc. I've also used the network troubleshooter in windows10 which told me a problem was not found.
Nothing seems to change the light back to green. Can someone help me find the problem so I can fix it?

 

IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.



Solution 2: No Internet Access In Windows 8.1,windows10

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs
