[開箱]Buffalo WZR-HP-G300NH無線IP分享器

筆者以前十分重視無線IP分享器的Router機能,總是堅持使用連線數高、記憶體大、能自行微調Firewall和QoS、能支援各家Dynamic DNS服務、能自行加載VPN Server和SSH Server等其他多樣化服務的IP分享器,因此當時選擇了這台便宜、改造空間極大的Linksys WRT54G-TM無線IP分享器。只是,WRT54G-TM的無線規格畢竟是IEEE 802.11g,對於現代的無線AP來說,WRT54G-TM的無線傳輸已略顯老態。正好,最近擔任家中區網Switch、傳輸速度為1Gbps的Linksys SD2008出了問題,有線網路的訊號有時會抓不到,想送修又覺得不划算,於是就想找台無線傳輸速度300Mbps、有線傳輸速度1Gbps的無線IP分享器,以取代現有Switch的有線通訊機能和無線IP分享器的無線通訊機能。

考究了一下市面上常見的無線IP分享器後,我敗了Buffalo WZR-HP-G300NH:

拆膜!

開箱!

說明書與光碟下面放的就是WZR-HP-G300NH本體:

水牛牌的無線IP分享器向來品質都夠穩定,不過這台WZR-HP-G300NH表現普普,在150Mbps傳輸模式下,每秒只能傳輸5MB/s左右,而且開機時間很長,分享器的設定頁面換頁速度也很慢。另外,這台有個致命傷,那就是不支援5GHz頻段的無線傳輸。由於一般筆電所使用的無線網路裝置,在硬體設計上大多只允許在5GHz頻段啟用300Mbps傳輸模式,這也就表示WZR-HP-G300NH沒什麼機會可以發揮300Mbps的傳輸速率,再加上2.4GHz頻段的干擾實在太多,就算無線網卡支援在2.4GHz頻段啟用300Mbps傳輸模式,也很少有機會可以在2.4GHz頻段維持300Mbps的傳輸速率,所以這台的300Mbps傳輸模式就形同虛設。還好它的有線網路傳輸效率不差,價格在支援1Gbps有線傳輸速率的無線IP分享器中算是很便宜的。再者這台有USB Port,要接硬碟當省電的File Server或BitTorrent下載機,還是接個3G Modem分享廣域無線網路資源給區網,都沒有問題。

總合來說,這台的特色就是"花小錢就能得到無線傳輸速度300Mbps、有線傳輸速度1Gbps的帳面性能"。如果想要一台實質傳輸效率比較威猛的無線IP分享器,我個人還是建議敗Buffalo另一款無線IP分享器:WZR-AGL300NH,畢竟這台才有支援5GHz頻段的無線傳輸,只是WZR-AGL300NH不支援USB裝置就是了。
