WRT54G Version 2-4 Power Supply Question

    I have been running a WRT54G version 4 for about two years now. It has workked correctly until very recently. I started to get very poor response at times. Sometimes it was as slow as a 2400 buad modem.

    I moved from the standard software to DD-WRT 23 and it seemed to speed up for a while but by the next day it was slow again.

    I then decided to change the power supply. It is a 12V 1 Amp wall wart and I had another one with the same specs. I installed the new supply and things have been working great for about 3 days now.

    The large capacitor went bad in my 5 volt V1 power supply but there has not been much mention of problems with the 12V supplies that come with the version 2-4.

    Has any one else seen this problem?

    Never had this problem with a Linksys power supply unit, but with many other (driving different things). Capacitors don't like it hot, so after running hot for a while, they tend to "go bad". Even the insulation on transformers sometimes gets eroded away, resulting in shorts which takes your supply's output down a few volts, or makes it go smokey....

    I find it strange though that the PSU could be causing the router to slow down???

    It has now been about two weeks and the router is working fine. I think it may well be a capacitor that was allowing 60 cycle noise to get onto the 12V DC. This might have been causing it to do retries which would have slowed it down.

    The new power supply fixed the problem.
