content: First post.My Linksys wrt610v1 router has failed on me. On opening it up I can see that a crystal with the following markings "NSK 8D 25.000 ALG" looks like (see attachment) it has leaked something.I don't know enough to know whether this is a symptom or cause of the failure. All I can try is replacing the part. The crystal is 3.5Hx10Lx3.6W, thru pin 4.7mm apart.Can you help me identifying a suitable replacement part (I live in the UK) and how I might do it myself in the future. I have of course tried Google etc but I've only got close.Any other suggestions welcomed.Isihac

content: You can replace it with almost any 25 MHz crystal. But I can guarantee you, that is not going to be the broken part. Crystals are hermetically sealed, so nothing gets in or out of them. Look for broken capacitors or firmware that is way more likely to fail.

content: I see 26.000 on the picture, not 25.000, but crystal haven't leaked anything. Actually there is nothing to leak in it. These are just flux residues because there is a solder blob on the left side. And 100% the fault is not because of the crystal.

content: Hmm, get a linksys WRT54GL instead. Then you can add an SD card, extra ports, linux distro, use it to control a robot, lots of hacks. You can reflash the wrt610v1 as well though. Do fancy stuff with it.

content: Check if capacitors are not of some crap brand. I've seen linksys routers with crap Su'scon capacitors inside, almost all of them were dead.Quote from: TheElectricChicken on August 16, 2015, 11:11:38 amYeah, really "nice" idea get that prehistoric junk.

content: Quote from: TheElectricChicken on August 16, 2015, 11:21:27 amYeah, as if this prehistoric router which isn't even of 802.11n standard is the only router which can be hacked. They are so old that are dying because of the crap capacitors used in them. I can flash DD-WRT on my 5 months old router supporting 802.11AC too BTW.

We have terrible conditions here in Nigeria, we get our feathers clipped so that we can't fly out of the factory and we have to use windows 10 all day long and for just no reason at all they play bieber through the public announcement system sometimes.

content: Quote from: TheElectricChicken on August 16, 2015, 02:12:38 pmWhy to make useless posts in the first place? Op asked how to fix the router, not how to buy another junk which is older than his own. That comment was already based on the fact that you make such useless posts over many treads. Like yeah, another piece of garbage.
