fujitsu notebook  無線上網問題 (用線上網完全冇問題--經router)

現象 1.

Fujitsu notebook + netgear wnr2000 wireless router

nb detect 到個netgear 但連唔到internet


現象 2.  

fujitsu notebook + pci 11b wireless router

nb detect 到個pci router 同埋連到pci router 但上唔到internet

pc ---- v (ok)------pci router (wireless) ------- x (not ok)------ internet

又係fujitsu~
fujitsu嘅原有wireless lan 一定要用返部機本來有嘅無線連線軟件先可以連到架~
同埋有陣本身自帶嘅軟件有問題,要自己上返官網度dl~

亦有可能係有部份router係wireless果一part度有20Mhz或40Mhz~
多數啲較舊嘅wireless lan card都連唔到呢個option~
要set死做20Mhz~先可以畀啲較舊嘅wireless lan連唔到~
你睇下有冇呢option??
linksys wrt行802.11n系列就有呢個啦~

同埋你部router嘅說明書都有提過~

Mode. This field determines which data communications protocol is used. You can choose
from:
– Up To 54 Mbps. Legacy mode, for compatibility with the slower 802.11b and 802.11g
wireless devices.
– Up To 145 Mbps. Neighbor Friendly mode, for reduced interference with neighboring
wireless networks. Provides two transmission streams with different data on the same
channel at the same time, but also allows 802.11b and 802.11g wireless devices. This is
the default mode.
– Up To 300 Mbps. Performance mode, using channel expansion to achieve the 300 Mbps
data rate. The WNR2000 router will use the channel you selected as the primary channel
and expand to the secondary channel (primary channel +4 or –4) to achieve a 40 MHz
frame-by-frame bandwidth. The WNR2000 router will detect channel usage and will
disable frame-by-frame expansion if the expansion would result in interference with the
data transmission of other access points or clients

仲有note~

Note: The maximum wireless signal rate is derived from the IEEE Standard 802.11
specifications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building materials
and construction, and network overhead, lower actual data throughput rate.

有無upgarde 最新driver?
因為都有可能唔夠新~
