I have re-install the network adapters,it is work
but when I reboot the computer , it can not access the network

what should i do?

 

[Ztruker]

Open Device Manager and see if any areas (Network Adapter or Unknown Devices) has a yellow mark by it.

When you say you re-install the network adapters, do you mean you downloaded and installed the driver?

What is the make and model number of your computer.
Laptop or Desktop?
How do you normally connect to the internet?

Go to network center (type start) --> edit adapter settings --> select your adapter and choose settings
check of IPV4 and IPV6 stand automatic. (sorry picture is dutch)

If that is correct, check that your workgroup settings are the same like the network.
question: witch operating system are the PC in the network?

windows 7

oh, you does not have a connection at all. Are you sure that al drivers are installed?

 

[wonglaiyin]

yes,but i must re-install the driver when i open the computer,because if i do not re-install the network adapter driver , i will can't connect the network

I think I would start by disabling or uninstalling all those virtual network adaptors.

 

[wonglaiyin]

is the problem is multiple network?

 

[chev65]

Yes those virtual adaptors are all active, you need to disable them or uninstall them if you aren't using them. This network is a mess for sure.

 

[wonglaiyin]

I hope it can work.
But before that there is no problem when i using

 

[wonglaiyin]
