It's the wrong icon because it has errors. The symbol it's showing is indicating a problem.

Without us knowing what that problem is we are unable to help you.

Clearing the problem will restore the icon you are trying to get. Try right clicking on it and going through the troubleshooting.

i did try that no errors.its a misterie.

Reboot the router (i.e. disconnect it from the mains for around a minute then connect it again)

Update the driver for the WiFi NIC along with any other driver updates available for the PC.

The icon is indicating a software issue, most likely the configuration of the router or of the NIC itself.

i think your wright. earlier first wifi was d-link whit some reciever.when they installed on my new adres,they didn use the reciever.dont know why.mybe i need to call them back.

OK it's saying that a network cable isn't connected... what network adapters are installed?

Post a screenshot of

Control Panel\Network and Internet\Network Connections

It may just be a case of disabling a network adapter that's not in use but is reporting an error because it's not plugged in.

Disable all network adapters which aren't being used, more specifically the two with the red crosses on them (not the bluetooth one though).

You should remove all adaptors really since it looks like there may be a few which aren't really there but for now just disable them and see if that solves it.

rich you have an amazing brain.problem solved. it was the first adapter from an old robot i had online.

thank you all .
