Vista - Continual Networking Problems

oI have several gripes about networking issues with Vista. I'll list some
here in hopes that someone can help with any/all of them.

-After my laptop comes out of sleep, networking support is often completely
gone. I will get an IP address from my DHCP server, but I won't be able to
access any resources. A ping to the gateway results in an error message that
says General Failure. I must reboot to get it to work again.

-When I need to change the IP address of my network adapter, I try to open
the properties tab of my local network card. When I do, I always receive the
following message " Some of the controls on this property sheet are disabled
because one or more other Network property sheets are already open. To use
these controls, close all these property sheets and then reopen this one."
There are no other property sheets open. This message will appear anywhere
from 4 to 17 times before it actually allows me to edit the properties of the
network card. If I continue to retry, it will eventually work.

-Wireless networks will not automatically reconnect to networks that don't
broadcast their SSID. Yes, I select to reconnect them each time and it fails
every time. I have to go in manually and redifine the SSID and keys every
time I connect.
Previous versions of Windows did not behave like this.

Any feedback is welcome.
