I will try and stay calm and coherent, but I have been working on this for over 12 hours straight now. I had been having issues getting my "guest network" to function properly and followed the lead of a thread found hereand flashed to a community dd-wrt build. When that didn't solve my issue I decided to revert back to facotry Buffalo firmware. I didn't realize, however, that the biggest difference with the WZR-HP-G300NH2 revision is that the normal "flash to 1.65 via dd-wrt webgui" method for the WZR-HP-G300NH doesn't work, and I was left staring at the constant red glow of the Diag icon on a bricked router.
I did manage to follow the steps found here to TFTP (via PumpKIN) an OpenWRT build successfully onto the router and I can access it via Telnet, but there's no webgui and I've never even heard of telnet before so I'm at a complete loss.
I just need to get this router from it's current utterly useless state of telnet-only openwrt to some form of dd-wrt or factory firmware that has a webgui I can work with. I've currently got my PC hooked up and online with my old Linksys WRT54GSv7.2 on it's own DD-WRT firmware via USB wifi adapter (to save my one LAN port for connecting to the Buffalo if necessary, but I can easily switch) but I really need the Buffalo router up and running as my main gateway (Linksys was a client bridge on another PC) and I've only had the thing for 6 days.
I did see something about flashing DD-WRT through the OpenWRT telnet by setting up an ftp server on another computer, but I have no idea how to do that, or how to even plug all the necessary PCs into one/both of the routers so that I can use said ftp server. Since I managed to get it as far as telnet access with minimally functional firmware I can't believe that it's completely bricked (or that I spent $65 on a router that's not even a week old and is completely FUBAR) Please, someone, anyone, help me, I can't bang my head against the wall anymore.
