most of the time my Belkin mouse will work great, today it won't do anything, i do not think it is the batteries. what do you think the problem can be?

Your wireless mouse is likely using Bluetooth in the 2.4 GHz industrial band which is shared with other wireless technologies such as cordless phones and 2.4 GHz WiFi. The Bluetooth protocol was designed to minimize likelihood of it interfering with anything else in the band in that it will refrain or back-off from transmitting in the presence of other signals. Unfortunately, this means that often, bluetooth is at the lowest priority and devices using it will be slowed down or stop working in the presence of interference. Its signal also tends be the lower than the others as it was intended to connect nearby peripheral equipment such as a mouse, printer or scanner to a computer. WiFi and cordless phone signals are much stronger as their coverage is typically for a whole house. The congestion on the 2.4 GHz band is being relieved somewhat with the use of the 5 GHz band for newer wireless technology and you may want to take advantage of this by replacing existing 2.4 GHz equipment with newer cordless telephones and WiFi with 5 GHz capability. In the interim, if your problem is on a computer that is close to your wireless router, you may find some relief by using a direct ethernet connection using UTP cable with RJ-45 jacks on each end to go from the computer's 10/100 LAN port to one of the four LAN ports on your router. Also, if you have a 2.4 GHz cordless phone in close proximity, you may want to relocate your cordless phones away from your computer.

The quickest and easiest way i have found is to press the Fn button + the one that turns on your wireless networking if you have one.
