Secure your wireless connectivity
Wifi stands for Wireless Fidelity. It is a very popular technology that allows an electronic device to exchange data wirelessly using radio waves over a computer network, including high-speed Internet connections.Most of the people rush through while setting up their wifi connection without thinking about the security of their wifi connection.It is quite understandable that they want to connect to Internet as quickly as possible and Moreover securing a wifi network is a bit tricky for most of the people so they give up their hopes quite early and leave their wifi network unsecured.

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.

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.

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.

Randomly all drivers stopped working
I have a Windows 7 Toshiba Satellite P505 2009 laptop. It was working fine until randomly all the drivers stopped working, besides graphics. The sound, Wi-fi, LAN, and USB drivers all have yellow exclamation points next to them in Device Manager.

I've tried updating them all, but they're all up to date. I even uninstalled them and restarted my computer but they still don't work.

I assume it's a problem in the operating system, and I'll probably have to take it in to repair it.

How to Disable Internet
Ok with XP I could enable/disable internet connection just from the system tray. Windows 7 does not have this feature is there anything quicker than opening network and sharing center then to local area connection and disabling it from there.

I really don't like leaving connection open all the time but surely there's got to be an easier/shortcut way.

Why can't I connect to the Internet?
Internet connection problems are most commonly caused by disconnected cables or by routers or modems that are not operating properly.

Internet connection problems
When I try and connect my Vista notebook, it can't find it, saying it's an "unknown network" though it identifies the adapter.

Network settings say it's a local area connection but it should say internet. I can't find where to change that on the adapter or the connection setting but it seems to think the adapter is lan only.

Computer shuts down randomly
I'll be on my browser, when suddenly my computer will start using quick find and typing in random stuff (most of the time its br/) or if I'm on google it'll type it into the search bar multiple times. If I'm not on my browser it just randomly moves between desktop icons.

Then firefox will crash. Sometimes it opens up the "do you really want to shut down" screen and I can cancel, but most of the time it just shuts down immediately.

When I try to turn it back on it'll take multiple tries because every time I get to the log in screen and try to type in my password it'll shut down.

I've dusted off the hardware, I've run multiple malware/virus scans but nothing has worked.
