I have Windows 7.
When I plug in the network cable the internet works fast, but when I use WiFi it's extremely slow.
Please help me fix this problem and also mention if the problem is with my WiFi device or with Windows itself (or other software).

Many possibilities exists.
What type of Wifi are you using 802.11 a/b/g/n or etc If you got "a" there is your problem right there.
How strong does Windows report the signal strength? If the distance is <10ft as mentioned you should have full bars.
How many other wifi networks exist that overlap yours? If another wifi router device is using the same channel as yours they will fight each other. Depending on how close the other wifi router is it will reduce your reception quality significantly.
You could be using a USB wifi adapter. If the usb port were 1.0 or 1.1 or running at that version of usb there is your problem.
You wifi router could be malfunctioning. How old is it? Has the firmware been upgraded?
Go to the store with a friendly return policy buy a new one try it for a day and if it sucks also take it back for a refund. If the new one is awesome problem solved.
