Hi,everybody. My router is WRT54G V1.0. I used it for a time.It works fine.But now it doesn't work. I think the power part on the mainbord is wrong. When I plug the external power.The power led and diag led is on。But even I plug the net line，the lan led is off. And when be close to the router,I can hear some fizzle from the power part of the mainbord. So I wonder if anyone can give me the circuit diagram about the power part or the whole mainbord. Or anybody can help me about this. Thanks a lot.
