Is there any way I can use wireless keyboard and mouse without inserting its USB stick into the USB port? By just using the WiFi available on the laptop.

With the current keyboard/mouse that you have, probably not unless some networking/programming guru can strike me down and tell me otherwise. With that said, if a WiFi (802.11x) keyboard/mouse combo ever came to market then I would imagine that it's battery life would be dreadful. –  MonkeyZeus May 3 at 12:30

Are you asking if it is possible to make a mouse that works that way, or if it's possible to take a mouse that uses a USB stick and use it without the stick? –  user2357112 May 3 at 20:03
    
My intention is to ask both ways. Any way, I want that I don't insert anything into my USB Port and still I get wireless mouse and keyboard that will work. –  teenup May 3 at 20:28

No. A wireless mouse/keyboard does not use regular WiFi (i.e. 802.11x) and can only bind with the receiver it came with. (An exception may be the Logitech Unifying receiver, which allows connecting every Logitech device that supports it, to a single receiver - but still, it will take one USB port.)

If you do not want to use a receiver, consider using a Bluetooth mouse and/or keyboard.

Bluetooth is probably the way to go. Many laptops now-a-days have an internal Bluetooth receiver built in that you can take advantage of with Bluetooth keyboards, mice, headphones, speakers, microphones, etc. If your laptop doesn't already have one, depending on the laptop you may be able to install your own (card slot?). –  Doc May 4 at 19:33

Yes and no. Yes, this is possible. No, it doesn’t work with WiFi (802.11).

Instead, this can be accomplished with Bluetooth, another wireless technology built into most modern notebooks. If yours is equipped with it, you can use Bluetooth mice and keyboards. There’s plenty available.

That would require a different mouse or keyboard though. –  Arjan May 3 at 11:11
    
Well, he didn’t exactly say he already had some. –  Daniel B May 3 at 11:41

True, but I think that the bold "Yes, this is possible" or using bluetooth does not match "Can a wireless keyboard mouse work with laptop's wifi rather than inserting its own usb stick?" and "use wireless keyboard and mouse without inserting its USB stick". –  Arjan May 3 at 11:51

To fill in a bit more explanation to some of the great answers already given:

The WiFi (802.11 a/b/g/n) requires having some kind of a central authority to pass data around -- called an access point.[1]

Your computer connects to an access point as a client... often having to enter some kind of authentication -- WEP key/WPA Key/etc.

Imagine if you had to enter this key into your keyboard or your mouse before they could connect to the access point and then connect to your computer.

In reality, this just doesn't work -- so alternative methods of connecting from device to computer were invented. Simpler protocols such as bluetooth and whatever else is out there.

[1] For the moment, I am skipping adhoc networks, but those are rare.

Actually, HP makes a Wifi Mouse. I have one and it works most of the time. It is called the "Wi-Fi Mobile Mouse". http://www.hp.com/go/wifimouse

As others have mentioned, Bluetooth is a better way to go.

Yes, this is possible, in theory, but the chances of it being possible with the keyboard you already have, or with any keyboard that is likely to exist COTS, are pretty much zero.

Data radios come in many different types and variations, and they are not interchangeable. For this to work, would require that the radio built into the keyboard be built to operate on the Wifi band, using the Wifi protocols. In practice, people who design and make wireless keyboards do not usually choose this band or this protocol, for a variety of technical reasons, most notably that Wifi radios tend to be very power-hungry, negatively impacting battery life.

Most wireless keyboards instead use a Bluetooth radio, with a significant minority using some other band that I don't know the identity of, but do know that it is neither Bluetooth nor Wifi. The closest things I know of to any existent Wifi-using wireless keyboard are a few tablet/smartphone apps which turn those devices into wireless keyboards, and which use Wifi because the radio is already there in pretty much all such devices.

Although possible in theory, you would find that it would drain the battery of the mouse very quickly (i.e. in a matter of days). WiFi is extremely power hungry, and low power solutions such as BlueTooth or ZigBee are far better suited.

In addition, WiFi is difficult to set up without some sort of visible console to select the the WiFi password, encryption type, etc, which creates a bit of a catch-22 - how do you enter the password for WiFi if you don't have a keyboard set up yet?

Thus, the market has moved towards efficient, low-power, low range devices to transmitting keystrokes and mouse movements to a laptop.
