Hi. I have a ws 8 150 ac which likes to get stuck in a reboot loop without reason, I'm going to buy a serial cable to see if I can get output but I was also reading up on it and seems like there seems to be a 3.3v cap issue on these, I wanted to know how can I go about repairing that on my own? I have the skills to add a new cap, or replace the old.

no replies? thankfully I dug enough to figure it out. There are two capacitors,
C1 and C2, they're in parallel, so you can choose either to work on.
Throw on a bigger, badder cap. I threw on a 25v 680 uf I believe, it's what I had and it's working great. No bootloops. I have some others I can try out if this one doesn't result, but I salvaged this from an old motherboard, and since it's 25 volts only doing 3.3 volt it'll live quite the bit.
The side of C1 most towards the chasis is +
the side of c1 most towards the ethernet ports is -
Hope that helps anyone else! I couldn't resolve it for the life of me.
