(reinforced cement wall ). We know that in order to reduce the radiation to the human body, the power of the wireless router is generally not large, so the capacity is subject to interference from nearby electronic devices during use, therefore, when setting the placement of wireless routers, we must remember to stay away from microwave ovens, refrigerators, and other household appliances. A good antenna is also an effective way to ensure the wireles

transmission distance is not a problem. But the family environment has brought a new problem, that is the family space is more crowded, the space is not open, in which the walls of the room is the main obstacle. Because Wireless LAN uses the wireless microwave frequency band. The most characteristic of microwaves is that it is almost linear and the diffraction ability is very weak, so the wireless receiving device behind the obstacle receives a faint signal or does not receive a signal. What ab

). Troubleshooting: When mixing IEEE 802.11b and IEEE 802.11g wireless devices, be sure to set the wireless AP into a mixed (MIXED) mode, which can be compatible with both IEEE 802.11b and 802.11g two modes. Wireless network connection is not 2: The wireless client is not receiving a signal failure phenomenon: After building a wireless LAN, the client is found not to receive the wireless AP signal. The wireless network has no signal. Failure Analysis: There are several possible causes fo

NW335 150M Wireless USB card NW335 is a cost-effective 150Mbps removable antenna USB card, it is widely used in the environment than ordinary USB card wider, product performance is better, is the formation of wireless LAN and extended wireless signal coverage of the excellent terminal equipment. NW352 150M 11N Wireless PCI network card (for desktop exclusive) NW352 is a high specification, strong performance of th
suspected that pilot contamination may exist, the first possibility is that there is not enough protection in pilot planning, and the other may be that the time tolerance of pilot channel of some base stations has a large deviation. For the latter, a transmitter tester can be used to test the potential base station. (Computer science) The user complained to the warning and network management reports that there is a problem with the call, and has ruled out base station and base station day feed
of wireless networks is much more difficult than ensuring the security of wired networks. Because the wired network only has a limited number of fixed access points, and the wireless network can be connected from any point in the range permitted by the antenna. Design antenna placement The first step to keep the Wireless Access Point Closed is to place the antenna

points or wireless routers as wireless base stations, basically not involving bridges. How wide is the coverage of common Wireless AP? According to the protocol standard, the coverage of IEEE 802.11b and IEEE 802.11g is: 100 indoors and 300 outdoors. This value is only a theoretical value. In practical application, in addition to signal connection, it also has the value of speed. Therefore, the actual use range of Wi-Fi wireless products is: 30 meters indoors and 100 meters outdoors (no obstacl
sometimes called space diversity because it uses multi-space channels to transmit and receive data. MIMO can be deployed only when the site mobile devices) or access point AP (AP) Support MIMO. MIMO can increase the wireless range and improve the performance. The 802.11n site connected to the old 802.11g access point can connect to farther distances at a higher speed. For example, if you use an old site, the connection speed from 25 feet to the access point is 1 Mbps, and the site speed is 2 Mb
, this naturally slows down the WLAN transmission speed. In addition, the wireless network transmission distance is limited, although the average wireless router nominal transmission distance can reach 100 ~ 300 meters, but in actual use, if there is a barrier, this distance will be sharply shortened and will cause data transmission to slow down. Knowing the cause of slow transmission speed, we can solve this problem in a targeted manner. First of all, we need to grasp the layout. It is best to
Many of you are not quite familiar with the linksys Wireless Route Test content. So here we have compiled a blog article to share with you, hoping to help you. The following is the specific content: Yu Xin Computer Co., Ltd., a merchant that has been discussed on the internet, purchased the protagonist WRT54GC for today's test at a price of 369. Take it home with excitement and tension, skillfully connect the cables, and put the CD into the optical drive. According to the wizard prompts, all the

, or when there is an obstacle, the distance should not be too long. If you really need it, you can set up a relay station in the middle to bypass the obstacle. During WLAN close-range transmission, in order to obtain the maximum bandwidth, you can connect the wireless bridge to a router that supports redundant channels, so that three wireless bridges can be integrated together, in addition, the antenna height is basically unaffected. Most WLAN device
