WRT54G AC adapter destroyed, need replacement

    Well, the topic title pretty much explains itself. My AC adapter has been destroyed, and now I am left with no router to use.

    Where can I acquire the least-expensive AC adapter that will work and get my router online again?

    I don't see why any generic 12VDC 1A adapter with the appropriate size connector wouldn't work. Of course, if it's a WRT54G v1.0, you'll need a 5VDC 2A adapter.

    Depending on where you live, it looks like Radio Shack 273-1776 (12VDC 1A) fits the bill, although I haven't verified this personally.

    Hmm...Would you happen to know how much mA the router can withstand before going kablooey? Because I've got a 1.25 A 12VDC adapter here that looks like it'd fit, but I don't want to mess up the router by overloading it.

    That should work fine

    The amp rating is strictly how much the router would be allowed to draw, not how much would be forced on it. As long as it is 12 v and greater than one amp there shouldn't be a problem with heating, etc. Check your other adapter to make sure the center post is also + like the Linksys adapter-there should be a picture on each.

    I had left my wall adapter at my parents place ( in a totally different state). I went to Wal-Mart a purchase a universal power supply with selectable voltages and had 1 am maximum output. It ran fine until I could get my adapter back (months later). Further more my router was tweaked (OC and xmit power boosted).

    Sded is right. The amp rating is the maximum the adapter will produce when needed. The router will not fry from the replacement power supply... Unless you mix your polarity or have it set to the wrong voltage itself.
