After my first attempt to configure my Buffalo WZR-HP-G300NH2, I lost ethernet access to it after I either Saved or Applied the configuration. Unconcerned, I simply reset the device using the Reset access hole. I have never gained config access to it since. During the initial config, I attempted to set the LAN IP to 192.168.0.1. Though not shown below, attempts to ping that address, while on that network, failed as well. I presume that a hard reset will take the device back to the initial config address of 192.168.11.1. I lost access to the device before I could discover the DD-RT Rev number. === Running Slackware on Acer Aspire One 722 root:~# uname -a Linux gaza 2.6.37.6 #13 SMP Tue Jan 31 22:31:22 CST 2012 i686 AMD C-60 APU with Radeon(tm) HD Graphics AuthenticAMD GNU/Linux Acer comes up on network 192.168.0.0 network: root:~# netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.0.7 0.0.0.0 UG 0 0 0 eth0 Re-config network to 192.168.11.0: root:~# ifconfig eth0 down root:~# netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo root:~# ifconfig eth0 192.168.11.7 netmask 255.255.255.0 root:~# netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.11.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo root:~# route add -net default gw 192.168.11.7 metric 1 root:~# netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.11.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.11.7 0.0.0.0 UG 0 0 0 eth0 Ping myself: root:~# ping 192.168.11.7 PING 192.168.11.7 (192.168.11.7) 56(84) bytes of data. 64 bytes from 192.168.11.7: icmp_req=1 ttl=64 time=0.127 ms 64 bytes from 192.168.11.7: icmp_req=2 ttl=64 time=0.093 ms ^C --- 192.168.11.7 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 0.093/0.110/0.127/0.017 ms Ping Buffalo WZR-HP-G300NH2: root:~# ping 192.168.11.1 PING 192.168.11.1 (192.168.11.1) 56(84) bytes of data. ^C --- 192.168.11.1 ping statistics --- 105 packets transmitted, 0 received, 100% packet loss, time 103999ms No answer.

I put two laptops on the same network, and conducted a bidirectional ping over the same cable. Any ideas how I can regain access to this little jewel? Thanks.
