Random Eradic Behavior

You may experience random connectivity issues when you connect a Windows-based mobile PC to certain Wi-Fi "hot spots." These connectivity issues include the following:

• The wireless network connection is dropped.
• You experience poor performance.

You experience these issues if the computer is running on battery power.

Note You may also experience these issues when you connect a Windows-based mobile PC to a wireless access point (AP) in a small office/home office (SOHO) environment or in an enterprise environment. Cause This issue occurs if the Wi-Fi hot spot uses wireless APs or routers that do not support the 802.11 power save protocol.

This issue occurs because of the power saving features that are included in Windows. The default power plan that Windows uses for a mobile PC is the Balanced power plan. The following is true for mobile PCs that are configured to use the Balanced power plan:

• When the mobile PC is plugged into a power source, the wireless network adapter is configured to use Maximum Performance mode. This turns off 802.11 power save mode.
• When the mobile PC is running on battery power, the wireless network adapter is configured to use Medium Power Saving mode. This uses the 802.11 power save mode.

When an 802.11 wireless network adapter that is set to use power save mode wants to enter a sleep state, the adapter indicates this intention to the wireless AP. The adapter does this by setting the power save option in its packets or in the 802.11 frames that it sends to the wireless AP. In this scenario, the following behavior should occur:

1. When the wireless AP receives the frames that have the power save option set, the wireless AP determines that the client network adapter that sent the frames wants to enter a power saving state.
2. The wireless AP then buffers packets that are destined for the client network adapter.
3. When the radio of the client network adapter turns on, the client network adapter then communicates with the AP to retrieve the buffered packets.

This behavior enables the wireless network adapter to use less power and to wake up periodically at the correct time to receive network traffic from the AP.

If the wireless AP does not support this feature correctly, the wireless AP continues to send packets to the client network adapter even if the client network adapter radio is turned off. Therefore, these packets are lost. In this scenario, the symptoms that you experience may vary depending on the phase of the wireless connection in which these packets are lost.

most likley a loose cable or "ghosting" go to your local pc shop for help

the first thing that I would recommend is making sure that it is clean underneath since it is optical debri on the laser area can cause eradic behavior. My second suggestion would be to uninstall the software that came with it and just use the standard controller. I had to do that with a trackball that I was using because the software that came with the trackball wasnt playing nice with the operating system but once I removed that software the unit worked fine.

Hello Glennfulcher,
The Adesso WKB-4000US wireless keyboard is a great one! I use to have one. What problems are you having with the keyboard? If you are having issues connecting it to the transmitter I would first suggest you check any cordless phones you have around the house. As the WKB series operates at 2.4GHZ so do most cordless phones. This can cause a transmission error with your keyboard. Try these steps if you are having connectivity problems. Because this is the most common connection problem with wireless keyboards and mice.
1. Check all cordless phones for frequency range. 2. If you find a close 2.4 GHZ cordless phone unplug it. 3. Attempt to reconnect the keyboard to the transmitter.
As I am not 100% sure what your question is I'll just give a quick summary of links that may help you get started.

Thanks always, Vex

You have to download the software from Logitech.com and install it. The software will help you encrypt a connection and make it start working again. The software will prompt you to type in a set of numbers and the connection will be there again. Don't worry... your mouse and keyboard are not broken. This happens quite frequently.

I Belive this is the link you need.... according to the picture...

Sounds like your keyboard has died...Try to perform a reboot, and make sure the battery is seated correctly. You will most likely have to get it replaced. I recommend going with a Microsoft wireless keyboard and mouse. Its a lot better than Logitech!!

possible driver problem, try re-installing the driver with cd that should have come provided with it, if the keyboard is wireless check the batteries and make sure your within range of the reciever

If you know the batteries are good, then turn the keyboard over and find the small reset/connect button and press it. This resets /connects the board to the receiver. If it still doesn work, press the button on the receiver and then the mouse. Hope this is of help to you. Bud

Does this happen always or only in this game? If it is only in this game, then you may want to consult the game manual. If not, then it could be interference that may be causing the problem.

Any electrical device, such as the computer monitor, Zip drives, speakers, etc., can cause interference with cordless products. Most likely, this will effect tracking of pointing devices or the range of the device. Also, using cordless devices on a metal desk or a desk with a metal frame can cause problems with pointing device behavior and range. To resolve these types of issues, try moving the receiver at least 8 inches away from other electrical devices. Interference issues can also be resolved by moving the mouse closer to the receiver. You may also want to experiment with different locations and positions for the receiver, including moving the receiver to an upright/vertical position or rotated to a different angle. Another alternate solution is to elevate the receiver by placing it on a CD ROM case or other item.

Please let me know if this helped..
