YANO's digital garage

1月に続いて、年度区切りのおさらい。

6月からの10ヶ月間通しで覧ると、消費電力は平均84.5W、ピーク時172W。

予てよりLinuxで使える鉄板なRT3070系USB-WiFiアダプタとして愛用していたBUFFALOのWLI-UC-GN。無改造のubuntu 14.04 desktopで試してみたところ、あっさり認識した。

…と喜んだのもつかの間、デバイス"wlan0"としては認識され、NetworkManagerが"CTRL-EVENT-SCAN-STARTED"しているものの、NetworkManagerがESSIDひとつ拾えていない有様。rt2800usbのドライバがエラーを吐いている形跡がある事から、「やっぱりチップベンダーのRalinkからダウンロードしたDPO_RT3070_LinuxSTA～じゃないとダメなのかな…、取り敢えずRalinkから最新版をダウンロードするか…」と思ったのだが、なんとhttp://www.ralinktech.com/が消滅していて驚いた。

調べてみたところ2011年春にMediaTekがRalinkを買収したらしく、MediaTekのサイトで引き続きダウンロード可能な事がわかったが、最新版でも2年以上前の2012年10月なので、ubuntu 14.04のkernel版数3.13でbuildを通すのも無駄に難儀しそうだ。

そんなわけで、最後にもう一度だけrebootしてやってみたところ、NetworkManagerでESSIDが拾えるようになり、パスフレーズを設定する事で接続OKとなった。

BUFFALO WLI-UC-GN

但し、BUFFALO WLI-UC-GNもすでに生産完了してしまったのもある意味潮時。zd1211rwな2007年以来愛用のPLANEX GW-US54GXSも時代遅れだし、そろそろ腹を据えて世代交代しないとダメみたいですね。

2009年発売WLI-UC-GNに代えて試したのが、2010年発売の後継品WLI-UC-GNM。

11n(150Mbps)対応ながら指先サイズにまで小型化されているものの、「親機子機同時モード」に対応した後継のWLI-UC-GNM2が出た事で実売価格1000円以下。Amazon.co.jpでも無線LAN子機の中で最も人気のある商品となっている、まさに今が旬の商品を無改造のubuntu 14.04 desktopで試してみたところ、これまたあっさり認識した。

BUFFALO WLI-UC-GNM

ドライバは同じrt2800usbのようだが、wpa_supplicantも難なくパスし、何の苦労も無くあっさりWPA-PSKで繋がった。

というわけで、新定番決定。

これも既に終息商品ですが、ついでに試したGW-USWExtremeもrtl8192cuドライバでイケましたよ。
