Reddit reviews Buffalo Aoss2 11n/a/g/b 300 Plus 300mbps Wireless Lan Base Unit Wzr-600dhp2

Wow, handy! But my BUFFALO router is a Japan only model...

And I somehow get more than the "300Mbps" with a LAN cable...

I got that router cos I originally was gonna go on a 100Mbps or 200Mbps plan with eo net, but then they had a campaign for the 1Gbps plan.

Edit: it is supposed to be a giga wired, 300Mbps wireless. Bought it more than 2 years ago so I didn't remember and just reread the Amazon page.

I got the Buffalo WZR-HP-AG300H while in Japan

Looks like there is support for https://wiki.openwrt.org/toh/buffalo/wzr-600dhp2
Amazon still sell it https://www.amazon.co.jp/BUFFALO-AOSS2-300%E3%83%97%E3%83%A9%E3%82%B9300Mbps-%E7%84%A1%E7%B7%9ALAN%E8%A6%AA%E6%A9%9F-WZR-600DHP2/dp/B00CDJNMRY/ref=sr_1_1?ie=UTF8&qid=1504983015&sr=8-1&keywords=WZR-600DHP2

Edit: Looks like you have to flash it through serial or tftp according to forum posts
