First, wireless network connectivity failure is the main change is broken, more time is a wireless network connection will be disconnected for a while, for wireless router troubleshooting, wireless network card is much simpler, deal with this problem, our network will be restored as ever.
Second, wireless network connection when the first time to see the environmental impact, wireless card for the internal chassis radiated electromagnetic interference is more sensitive to HomeRF format led, 802.11b second. HomeRF and 802.11b are used in the frequency band of 2.4GMz, so the interference between each other is more serious, when both HomeRF and 802.11b at the same time network transmission, the two network data transmission speed will be greatly reduced, BER improved.
Third, if the 802.11B network using the NIC to the network card point-to-point mode transmission, it is likely that HomeRF and 802.11b can not work properly. All, must as far as possible avoid the multiple specification wireless network coexistence situation, separately uses separately. If they are 802.11b, it is best to set the same mode, to avoid mutual interference, but note that although the same set can still use the same frequency band, so how much still will be subject to some interference.
Four, there is in the installation of USB wireless network card requires a certain skill, it is in the traditional hardware installation sequence is the opposite, to install the network card driver, and then install the network card hardware, in line with the IEEE 802.11B specifications of the equipment are based on the signal strength automatically adjust the speed of the function, If the maximum data transfer rate is 11Mbps, but also can be based on strong and weak transmission rate adjusted to 5.5Mbps, 2Mbps and 1Mbps. To achieve its maximum rate, you can consider adjusting the AP installation location and antenna direction, if necessary, can also external antenna.
Five, 802.11b to join the network terminal number has a certain limit. For now, theoretically 128 are the largest simultaneous wireless network connections, but because the wireless access point background bandwidth is not high, so the wireless network connection to 30 users are more difficult, if the increase in user capacity, it may lead to signal quality decline, slow speed, the emergence of intermittent time, Even some user networking failed.
