LAN problem

  Sheila-Jo 00:36 20 Sep 2007


I'm unable to connect to LAN as I did before. I used to click on 'Local Area Connection' to connect to the internet but now receive the message 'Connection failed'.

I'm able to connect by going into 'Device Manager' but this is longwinded.

On connection, if I try to disconnect by clicking the icon near the clock, I receive the message 'It is not possible to disable the connection at this time. This connection may be using one or more protocols that do not support Plug-and-Play, or it may have been initiated by another user or the system account.'

I therefore have to disconnect via Device Manager also.

Can anyone help me please?

Thanks in advance,

If the network card is disabled it will cause this problem. check this in device manager. If its reporting to work correctly then uninstall it and reinstall the drivers. Next, check that the connection is using the network card by looking at the properties in network connections from control panel.

Thanks Streetwork and apologies for my late reply.

I have un- and re-installed the device and installed latest drivers but still no go.

Incidentally, the '1394 Connection' and the 'Wireless Network Connection' have the same problem also.

The only ways I can enable connections are: a) via 'Device Manager' or b) 'Network Connections/(X) Connection/Properties/Configure'

Any other ideas to fix the problem?

Just for the record I've fixed this now.

I did this by uninstalling a modem installed which I wasn't using any more.
