WiFi dropping out if not use for an hour

Windows 7 Home Premium SP1, 64bit, Outlook 2003 SP3, IE9.

On boot-up my WiFi connects fine, and remains connected as long as I am working on the Internet.

Once I leave the PC for any length of time, (less than an hour), or work for a while on a document with no need to access the web, my WiFi connection drops out.

The BT Internet application then wants to fix the connection and takes me through a long involved process where I have to identify my router, which connection I want to use, and often I need to enter the wireless key and sometimes the admin password.

If, however, I simply restart Windows, the connection is just made for me. It's not really mission critical, only taking a couple of minutes to restart, but I just think it shouldn't be this way.

Is there a setting somewhere I should select/deselect?

Improving Reliability of Your WiFi Signal Strength

Before we begin please note that this is about improving reliability of your wireless connection, not security. However following these tips are also good security aides. While it may seem counter intuitive ideally you have just enough WiFi signal being transmitted from your Wireless Access Point (WAP) to reach the desired area. Cranking up your Wifi signal strength to maximum just because you have it increases the likelihood of interference. Specifically it is called co-channel interference.

Windows 7 losing internet connection

Is anyone else having Windows suddenly announce "Lost internet connection" then shutting down the program you are on? At best, the "lost internet connection" seems to have lasted less than a few seconds.

Red X icon when connected via WiFi

When my laptop is connected to a wireless network I get an icon on the system tray with a red X like it's not connected as in the second image. Yet when I look in at "Control Panel\All Control Panel Items\Network and Sharing Center" it shows the correct icon as in the third image.

When I turn off the WiFi the icon does not change and when I turn it back on I get the searching icon as in the first image and then it goes to the red X again but I am connected to the internet.
Have search the MS site and tried a few things like deleting the connection and reestablishing and did a few registry editing no help. Did a Google search and there was a few more things to try including registry editing to no avail.

Losing details view

I've been using an install of Win7 home prem for 7 months. About every month a feature fails.

This month the 'details view' in windows explorer randomly changes to big non-discript icons. It undoes the general purpose and apply to subfolders on some, seemingly the most used folders.
anyway to regedit this permanently for all?

Computer randomly shuts itself off

My Windows Vista Desktop Computer will randomly shut itself off for no reason whatsoever. It is at a point now where it is expected it will do it because of how frequently it occurs. When it happens, my screen will read no signal, and the computer does nothing.

Then after roughly 10 minutes the computer reboots and asks if I would like to reboot normally or with the "safe" options.

I am not sure where to go from here or what action is necessary to resolve this issue.

Internet connection disappears

I have Windows 7 on both my desktop and laptop. Only on my desktop does this happen: After connecting to the internet several times (the number and time intervals vary randomly) I lose the ability to connect -- either via Firefox or IE.

I restart my computer and I can connect. This does not affect email or other connections to my isp. Since this never happens on my laptop(using the same router), I have ruled out an isp or router problem.
