Re: ZyXel Router



Yeah, I think I'm giving up on it. I don't really feel like doing as much work as it seems like I need to do, just to find out the CPU is dead.
I've gone back to the auction site and entered a complaint. We will see if that does anything... Doubtful! If not, I really didn't pay all that much for it so I'm not out a lot.



That's cool. I actually went and started searching the fcc site and was noticing that it seemed to all be wifi related items.

Thanks for all the help! I really appreciate...

Agent24, Thanks again for your help!

I probed the heat sink and within about 1-2min it was over 100C. Yeah, HOT...

U43 appears to be fine. Probably just the pic.

Yes, those are the WAN ports (there are 2).

When I attach my...

Thanks for the replies!

Agent24; the model is SyWall USG 50

Agent24/stj; I have attached some larger pics of the whole board and a more zoomed out of the specific area.

Thanks again!...

Hi all! This is my first real post here (besides my hello post).

I'm not sure if this is the right place to post this or not, but its not really a mother board but kinda is a mother board. Anyway....

I just purchased this off an auction site that will remain nameless... When I got it, it was DOA. So, I pulled it apart to find a bad Cap and resistor. Now I just need to figure out what they are so I can replace them and hopefully get this thing running again.

The parts in question are C9 and R27. C5 is right next to C9 but it does not appear there was...
