Linksys WRT54G hissing fix

Linksys WRT54 Stock

One of my Linksys WRT54G routers started to emanate an annoying hissing sound.  I figured that some of the capacitors must have been dying so I opened up the router.

These two capacitors need to be replaced with some low esr capacitors.

I used some Panasonic FM 220uf 25v DIAMETER: ~8mm HEIGHT: ~8mm DIGIKEY PART NUMBER: P12383-ND

Once replaced the router was silent.
