I have a tough one. I have a WHR-HP-G300N. I was noticing speed issues with my Internet connection, but when connected directly to the cable modem, they went away. I said, let's try upgrading the firmware from Buffalo version 1.7 to DD-WRT WHR-HP-G300N Professional Firmware V24-SP2 build 19154. The firmware seemed to flash correctly, but there is no response from 192.168.11.1. More correctly described, Chrome returns this response: Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
Command line request to 192.168.11.1 also fails to get a response.
I am using a wired connection to a LAN port on the router.
I have a new IP lease 192.168.11.146, and the default gateway and DHCP servers show as 192.168.11.1.
I don't think that it died during the firmware upgrade because the box is routing and I can connect to the Internet. A factory reset only reset my IP address and the network name.
Any Idea how I can get to the configuration / log in screen?
