HI, i have a buffalo WHR-G125, flashed using ddwrtv24sp1

Problem details
First occurence of problem: 24/11/08
Problem description:
All my router's back light lighted up... it happends just around 2 months after i flash my router to ddwrt...


And even i connect LAN cable to the port, and to my PC, window will just treat it as unplugged... .

I also tried to hold reset button for near a minute... unplug... hold reset... plug in... still the same, not working....

Usually the DIAG light will blink during boot up... but now it won't

I don't think it's the firmware's fault... but anyway... any body here can help?
