Vista - Vista home premium sudden loss of network

I posted this message to forum sometime back -
have been using Vista home edition on a Toshiba laptop for almost 6
months now without any issues when suddenly since last couple of weeks
I am having networking problems.

Suddenly in the middle of work the connection would be lost. I am
using wireless adapter.

So I investigated the issue but could not find anything conclusive.

When this happens I am unable to ping my router. Initially I suspected
my cable modem / router but that is fine beceuase I have another
laptop that works fine when this happens.

I now suspect that it is to do with a problem for which a hotfix is
available. It is called http://support.microsoft.com/kb/937168/en-us KB
937168.
Unfortunatley when I filled out the form I received an email from MS support
that the hotfix is not available!!!
Not sure where to go from here. Why write a KB article with a dangling
carrot when it leads to a dead end :-)

Are you using ICS?

Hi
This patch relates to ICS, if you have a Router you do not need ICS.
Otherwise it might be a marginal connection with the Wireless.
Try another Wireless channel.

No I was not using ICS. I tried the patch anyway but it does not solve my
problem.
The connection intermittently fails and the only recourse is a reboot.

Is anyone aware of any other patch like this, the symptoms tha this patch
talked about (albeit ICS) looked remarkably similar to my problem.

I have been experiencing the exact same problem Nasir describes,
except with a wired connection and not a wireless one. My network
connection will be up and running just fine after I boot my computer,
but it will inevitably go down at some point - maybe after half an
hour of being online, maybe 3 hours. I have tried unbinding IPv6,
doing an ipconfig/release and /renew, an ipconfig/flushdns, I have
turned off the option in the Power Management tab of the Properties
window for my NIC driver in Device Manager so that the computer cannot
turn off the NIC to save power.......I even installed Vista SP 1 last
night since I had read that it made changes to the way IPv6 was
handled and to how/when NIC drivers themselves were allowed to go to
sleep, but the problem persists. As stated above, the only solution
is to restart when the connection drops. I am connected directly to
the net (ethernet cable out the back of my cable modem and into the
port on my laptop), so it's not a matter of a bad router. At this
point, I'm not sure what else to try, short of putting a new network
card in the computer. Ideas, anyone?

Thanks!
