My wireless mouse - cursor refuses to follow sometimes!

The new router could very well be causing wireless interference. Try moving the router away or turning it off and see if the mouse works. If it does, try changing the channel number on the router to see if that is causing the problem as it's possible both the mouse and router are using the same wireless channel and clashing. You can usually find the channel option in the Wireless Settings page of your router setup web interface.

Hello, hope this isn't a silly suggestion, but have you pressed the 'connect' buttons on the mouse and receiver so that the 2 devices can synchronize?

Sometimes on wireless mice the contacts get warped or bent, so when you move it or set it down the batteries are not making full contact on both ends and the mouse loses power.

You can try adjusting the contacts or using a conductive material to make the contact (like a staple or paperclip), but you're probably better off spending the $10 or $20 to get a new mouse.

Try cleaning the lazer on bottom with a q tip with some rubbing alcohol on it. Check to make sure the reciever for the mouse isn't too close to any wireless router,phone,or microwave. In the control panel there are mouse settings you can play with too to see if that makes a difference. Re-install any software for the mouse.

if its a wireless mouse, it sounds like it needs to be snyced, refer to your manual or the internet for extact instructions but the snyc method is usally as follows, press the sync button on the reciever then on the mouse, sometimes its vise-versa, and sometimes you have to hold the button then press the sync button on the other half

Wireless device like the mouse needs a wireless connectivity to a computer like a bluetooth or a wireless receiver. Make sure that your mouse batteries are all working and the wireless receiver is properly plug into the USB(Universal Serial Bus) port of the computer. The wireless receiver don't need battery so you don't have to worry about it. The two both have a push button, press both buttons to activate the connection. Wireless connections has limit in distance so make sure that you are not too far away from the receiver while using the mouse and that is 9 feet or 2.7 meters so keep that in mind. When the cursor moves when you move the mouse, you have connected the mouse properly. If the cursor doesn't move, try repositioning the receiver. If it still doesn't work, you may need to restart your computer (if you haven't already) or reconnect everything.

Hope this could help you a lot..:-) Thanks..

bad mouse action , no other words need be said just that.
NO OP SYS STATED BY YOU< XP?
if the mouse is a wireless mouse, the battery is dead.
if the 1 mouse is wired it is bad.
if there are 2 mice connected , shut one down 2mice not allowed.

if the mouse pad is enabled then that is 2 mice if usb mouse used.
and not ever good to do that,
disable one of the mice. (easy no? rules)
i disable my LT here, , in control panel, device manager , mouse pad synaptic or what ever it is.
RC right click disable, it , I hate mice pads././/

Dust has built up in and around the touch pad. Purchase a can of pc dust buster, and give it a blast in and around all keys and the touchpad. You may have one sticky key which is causing the pad to behave erratically.

try using the fn and f9 to enable or disable the touchpad.

It's not the K/M, there probably was a surge that went through, and effected the motherboard in the computer. so you can take it to your local computer shop. But, before you bring it there, back up your important files because they might have to format your HD.
