Hi everyone. I have an new HP laptop that came with Vista and am running
into a problem. I am finding that when I make the computer sleep or
hibernate, that I can no longer connect to my wireless router (D-link 524).
When I try to connect, it tells me that it cannot connect to my router and to
physically connect my laptop via ethernet cable. If I try to repair it using
the right-click option that does not help. So far, the only solution has been
to restart the machine (some times multiple times). I know that the network
connection is fine since my XP machine can connect.

I went in and changed the power management settings as was recommended here,
but that has not fixed the problem.

What other steps should I try?

P.S. I am using WPA / TKI for my router security.

Many people including me have been tearing their hair out trying to
resolve this problem with Vista.

The error occurs when entering sleep mode on Vista 64bit OS, upon
resume the network card is powered and appears to be active, however no
network or internet connection is available.

The various fixes I tried which did nothing included:

1. Running MS update for patches (none found)
2. Updating NIC drivers (NVidia nforce)
3. Updating MOBO BIOS
4. Disabling IPv6 for all network adapters, including disabling IPv6 in
the registry
5. Every conceivable combination of settings for power options in the
OS and on the NIC, both hardware (e.g. WOL) and software (allow windows
to control...)
6. Reviewed output of ipconfig /all both before and after sleep (no
changes)
7. Locking IPs, subnet, default gateways on the NIC
8. Praying, voodoo, runes, etc.

In the end, the simplest of fixes sorted this out. I disabled and
uninstalled the NVidia NIC via control panelsystemdevice manager, then
rebooted.

Vista loaded up the original MS drivers for the card, and bizarrely it
works perfectly now, instantly reconnecting after sleep.

Hope it works for you as well.
