有幾個可能的原因,第一接收器位置,第二無線 IP 干擾。 以第一點來說,有時候接收器的位置會影響到接收距離以及效果,雖然說無線是沒方向性(實際上還是有),但是有看過天線場強圖的人都知道,天線端發射出的無線信號在各個角度是有不同強度的,所以可以把接收器移到 PC 前端試試。 第二點,無線IP分享的確定會影響,尤其在接收器的位置和無線分享器離的比較近特別明顯,可以考慮把兩者距離離開一點。另外就是可以調整無線分享器的通道,避開你鍵盤使用的頻道。
Any electrical device, such as the computer monitor, Zip drives, speakers, etc., can cause interference with Logitech cordless products. Most likely, this will effect tracking of pointing devices or the range of the device. Also, using Logitech 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.
NOTE: You should always get at least a 4 foot range. If you find that your cordless device gets less than a 4 foot range, please replace the batteries with a fresh set, perform the synchronization procedure for the mouse and/or keyboard and test the range again. If the range is still below 4 feet, please test your device on another system, preferably in a different environment. If you find it gets the same range on another system, please contact Logitech Support to obtain information about a warranty replacement. However, if the range improves on another system, then it may be an environmental variable. Use the suggestions above to resolve the environmental interference issue.
