Wireless network connection hangs up every couple of minutes

[Andy Piper]

I have a Vaio laptop connected to the home network
through a built in wireless LAN. The home network is D
Link connected to broadband.

When I use this computer on the internet then the network
connection hangs up every couple of minutes. I lose
connection, a few seconds later it reports no signal and
then I have to wait 15 seconds for it to reset and report
a 'very good'signal.

It hasn't always done this - but I don't know what has
changed.

My other Vaio with a PCMCIA wireless card works fine.

When I look in the event manager then I see "QoS [Adapter
%2]:
The netcard driver failed the query for
OID_GEN_LINK_SPEED."

Can anyone help - I am lost.

Thanks,

Andy

Hi try disabling the 802.1x authentication on your wireless network card
properties.
If 802.1x authentication is enabled on your wireless network card and your
access point doesn't support this authentication the connection will be
disconnected after a few minutes.

To disable 802.1x authenication over your wireless network card...

1.. Click Start, point to Connect To, click Show all connections, and then
double-click your wireless network adapter.
2.. On the General tab, click Properties.
3.. Click the Wireless Networks tab.
4.. Under Preferred Networks, click your home network, and then click
Properties.
5.. Click Data encryption (WEP enabled).
6.. Click the Association tab, and then click to clear the Network
Authentication (Shared mode) check box and the The key is provided for me
automatically check box, if they are selected.
7.. Click the Authentication tab, and then click to clear the Enable IEEE
802.1x authentication for this network check box, if it is selected.
8.. Click OK two times to accept the changes.
