===== What? =====
My notes for the Buffalo WZR-HP-G300NH wireless router, using it together with the Speedport 201 adsl2+ modem. The WZR-HP-G300NH can not work as a dsl modem itself.
  * specs: 400Mhz Atheros AR9132 rev 2 (0xb9) cpu, 64MB ram, 32MB flash, B/G/N wlan, 4x gbit ethernet, usb
  * shipped OS: DD-WRT v24SP2-EU-US (08/19/10) std - build 14998
  * pppoe login: zugangsnummeranschussnummer#0001@t-online.de

===== alternative firmware =====
  * OpenWRT: https://oldwiki.archive.openwrt.org/toh/buffalo/wzr-hp-g300h

===== using OpenWRT =====
OpenWRT is an alternative system. The webinterface has less options than DD-WRT, but on the commandline a package system is available. 
  * openwrt image exists
    * with attitude_adjustment/12.09 and trunk as of 04-Jan-2014 I run into the network taking more than 2 minutes to come up, and seeing this: "ar71xx: pll_reg 0xb8050018: 0x13000a44".
