Wi-Fi problem

Earlier this week when starting my Inspiron 3721 running Windows 10 Prof it could not connect to my wireless router: Running the diagnostics the following message was obtained:

  • Problem with the wireless card or accesspoint
  • WiFi misses a valid IP-configuration

How do I solve this problem?

I have other Windows 10 machines on the network as well as a printer and an internet radio and they all work fine

Looking forward to help

Best regards

Christian

RE: Wi-Fi problem

Does the WiFi device appear in the Device Manager under network adapters?

* Press Windows Key + R
* Type devmgmt.msc
* Click OK

When I run devmgmt.msc you see the networkcard containing: Broadcom 802,11nNetwork Adapter, PPoP WAN adapter, Realtek PCle FE Family Controller, a number of WAN Miniports. I can supply the result of the Windows' network diagnostics if you want.

RE: Wi-Fi problem

It will not restart the network automatically. When you try to do it manually you are back to where you started; the networkcard sees the network but cannot connect to it

RE: Wi-Fi problem

I doubt that the hardware has failed. Perhaps it is time to do an operating system reinstall. Have you backed up your data to USB key or USB hard disk drive? Did you make the operating system backup DVDs?

Hi,

Please check whether is it possible to connect another laptop with this network and check is it possible to connect this laptop with another wifi network.
