Hello, I'm trying to sort out an Acer Aspire 5050 laptop with Vista Home Basic (not too impressed with Vista so far).

The Internet was working ok for the end-user then stopped working for no reason.

I cannot ping external, internal or loopback addresses. Absolutely nothing, even when I have set it to a fixed IP address I still can't ping anything, even the loopback. A ping test gives a General failure response.

Also, it won't pick up a dynamic IP address. It only gets an autoconfig 169. address.

Any ideas anyone????

Wired, wireless, what?

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

I should have added, I cannot connect via the wired or wireless connection. Do an ipconfig and you can only pick up a 169. address. Give it a static IP and you still can't connect.

I'm still waiting to see the output I asked for.

I think to get to the proper command prompt in Vista it's Start Orb-->All Programs-->Accessories-->right click on Command Prompt-->choose Administrator mode. At least if you try to do an ipconfig/release ipconfig/renew you have to have administrator privileges in Vista.

[computertechie]

Thanks for your response lymponus. I've already tried that more than once in Admin mode.

It simply won't pick up a dynamic address.

I've tried the diagnose option many times now.

I've tried using the netsh int ip reset command to see if that fixed anything. No luck.

I plugged my laptop into the same port and that was fine.

Are there any addresses available from you DHCP scope???

I change the wired adapter to a static IP and here's the result. If I was to disable the wireless connector it makes no difference.

Yes, there are available addresses from our DHCP range. We've just plugged a brand new Windows Vista PC into the network and that picked up an address.

[crimsonnblue]

Try restarting the dhcp client service. Also another way to figure out wether or not this is a server issue or a desktop issue is to try pulgging it in to another network.

[computertechie]

I've tried the DHCP service restart 2 or 3 times already. Just done it again. No luck.

There's no server on this network, it's just a Netgear router with a DHCP range so we can update computers for customers.

It stopped working on the customers home network.

[computertechie]

I've also plugged it into our corporate network, makes no difference.

[computertechie]

There must be some clever person out there who has a solution :-)

I've also removed the adapters from Device Manager, which were automatically re-installed.

I've disabled the Windows firewall and the Symantec security software.

I've given it a static IP address again and in Network Connections it has changed to Netgear underneath the Local Area Connection, so it must be seeing our router by some means. Try and ping the router or the loopback and you get a General failure message.

Network discovery is turned on?
