So last night, I decided to get overly brave and do an SD card mod to my old WRT54G v2 router. I ended up toasting off RP3 with trying to solder the wires to it. After that, my LAN+WAN ports have stopped working. On the brighter side, my wireless is still working.
What I'd really like to do is to replace the component I damaged. The component was labeled "301" and is exactly the same as RP4 and RP5. If someone could help me locate this part or help repair it; I'd be very thankful.
A little more info on my router: it is a WRT54G v2 that has 32 MB of RAM. Printed on the board, it states that it is a WRT54GS REV:XB.
For some reference to where and what I was attempting to solder:
