Windows 10: Precision M4800 Dell Laptop not able to find my wifi network but can see my neighbors

I recently moved and the computer was working before. I got a new xfinity router but my laptop cannot seem to find our new wifi network. This has been going on for a few months now and I just cant find a clear answer. I have tried updating drivers but Windows says they are all updated. Please help.

Dell Precision 5820 no network connection

Hello together,

we have some Dell Precision 5820 clients, that we must migrate to Windows 10.

We are installing our clients with a unattended.xml file and joining directly during the unattend phase to our domain. The Windows PE phase are working very fine, the Windows installation and Domain Join also. But when there is coming the first logon screen,
the client have no network connection.

We have also some other 1.000 Dell clients (other models), that have not the problem. This is only on all Dell Precision 5820 clients.

When is working:

• When we let the client join a workgroup, then the client have a network connection. When we switch to the domain, the network is working also. If we rebooting 3 -5 the client, we have again our problem.
• Reboot the client with no network cabel and plug in few seconds later, after the client is started, the cabel. The client will become a IP address.
• The IP address will receive from our DHCP server.

I have testet the following steps, but nothing from there fixed the problem.

• Testet the original Intel network driver
• The latest Dell network driver
• Domain Join to a extra OU in the AD, with block inheritance GPO
• Disabled some speed options in the BIOS for performance (only 1 core, disable Intel SpeedStep)
• Reservation on the DHCP server
• Fixed IP address
• Plugin the Client to a DSL AVM FritzBox, but the same problem to receive a address via DHCP.
• Analysed on the client via Wireshard, there is only a DHCP discover.

Any suggestions what we can analyse?

Best regards
