WRT54G 1.0 Dead-No Power - Repair Ideas?

    Hi all,

    Anyone have any links or info on what tends to die in a WRWT54G v1.0 and/or how to repair said parts?

    I was using my 3yr-old one late last night and right in the middle of some serious file transferage, lost my net connection. I stumbled through the dark apartment (stepped on the damn cat, barefoot. Ouch?) and went to the room where the router & modem is, muttering not-so-silent curses at my cable provider, then I notice something disturbing: the cable modem's happily blinking, but the WRT, alas, was 100% dark. No LEDs. Nothing. Not even slightly warm.

    I checked the power supply which shows (5.17v at the plug), then continuity and voltages (~3.8v, I think) across every component inside I could, (I must admit, my circuit board repair skills aren't so great) and saw nothing out of the ordinary. How does one verify a bad capacitor with a multimeter anyway? :confused:

    I'm pretty sure this thing didn't get fried by a power spike, as everything's on a good UPS with line conditioner, and other devices on the same UPS showed no ill efects. The only thing I can think of is, a few months ago, I did install a HyperWRT 1.5c and upped the Tx power a notch (Next higher setting above the default) and since the thing's *completely* dead, not justthe wireless, I don't think that's the problem. So, I dunno. Ordinarily, I'd bin it and buy something newer, but this year, my normally tight funds are completely nonexistent, as I am now amazingly poor. So, I refuse to scrap it if I can help it. Fortunately(?) I had an old 802.11B BEFW11S4 that I was planning to sell, so I'm not completely out of luck, but might as well be, cos without the QOS, my activities (24x7x365 maxing out the connection) slightly interfere with the point-&-click activities of said connection's owner. So, the sooner I get a working WRT54G with QOS, the less griping and passive-aggressiveness I'll have to endure. :eek:

    Any ideas?

    Co-incidentally, my 35 months old WRT54G v1.0 died this morning. I do not know if it has any warranty or was it in 3-yr warranty term though. I gotta check it in the morning though...

    Could it be a dead power adapter?

    It very well could be, I don't have another 5V adapter, or even one near 5V with that kind of plug to test :frown: . I did order a universal adapter yesterday, so that's the first thing i'm going to use it for whenit arrives in 5-6 days.

    However - When I checked continuity & voltage on the original AC adapter, I was seeing a steady 5.18V at the plug, and was getting the same voltage inside the router to the capacitors, so unless something weird's going on with that adapter, I'm pretty sure it's just a fried component in the router. Just don't know which part! :)

    I also managed to negotiate myself a new WRT54GL from buy.com with the $30 checkout/rebate discount (found in link 3 days ago in these forums. Thanks to that poster, btw) so, I'll have that in 8-10 days. I still want to fix this one, though, either to mod or sell cheap to some other needy soul.

    kelaniz, how long from the date you purchased the router? It's completed 36 months period from day one you bought? Mine died, you know, in 35 months of service, and I called up Linksys yesterday and customer service said it's a defective model and I am getting a replacement.

    Hurry up...

    I know this post does not help fix your problem, but a friend just gave me a dead WRT54G v1.0 to play with after he bought a new wrt300n. When I took it home, I was hoping to reset it and load a newer firmware. However, when I powered it up it was also dead (no lights at all). I did not have a 5V power supply either so I was stuck and called it quits since I already a few other newer varieties working fine. I had seen in another thread at one point that there was an internal G wireless card so I wanted to stress that if you throw in the towel that only this particular router has removable G wireless card that fits some of the older laptops that have old internal B wireless cards. I just yesterday replaced the wireless card in my laptop (IBM T23) and it works like a champ (this was at the expense of the modem, but this was of no concern to me). Also, I was pleased to find out that the internal card was a WPC54GS v2 card which is probably more expensive than the price of the router alone if you were to buy a G wireless card for the older laptop. Point is you might be able to ebay that wireless card alone to defray the cost of a inexpensive new WRT54GL router. If I were in your shoes I would want to find a 5V power supply first to rule this out, but it that doesn't work or you can't find one then I would consider my alternative.

    That's a good point about the card. I did try the router with my universal power supply, and it powered on, but went into red-light diag mode. I figure it was either broken, or I killed it for good when I replaced the capacitors, since 2 other known-good 5V power supplies also didn't power it on. I've got it on my desk in as #2 in my to-do pile, (moving 750GB of data acquired over 16 years to a non-dying HD is first in line) I hadn't thought of ebaying the card, but that's an excellent idea. If it's still dead when I work on it, that's exactly what I'm going to do. (unless a laptop requiring one suddenly falls into my possession) :) Thanks for the post.

    Does anyone know of a service that repairs these routers?

    Why bother for a ver.1? Find a GL or buy new one.
