I've got this router running w0 in repeater mode, but NOT bridged. So using w0 to connect to WAN through another network and w0.1 and w1 to provide access to client devices.

I just pulled the latest build and it's been a bit unstable (crashes on applying wifi settings changes sometimes) and now, although it's working, it's capped out the CPU and got it running hot.

My questions are
1. Can you recommend a change of settings?
2. Can you recommend a more stable build?
3. Is there anything I should do before working around this to help devs diagnose it?

Thanks!

Update: top disagrees with the status panel, but /proc/dmu/temperature reports 902 / 90.2 C which seems way too hot?

Router is sitting on a flat surface in a cool room.

I did a 30-30-30 reset and things seem to be running better at the moment. Was still running CPU temps in the 80s but it sounds like maybe the heatsink on the R6700v3 just isn't that good and it does that. Putting a fan under it brought the temp down into the 50s.

I had formerly done a simple 7-second reset after installing DD-WRT because I read somewhere a warning against the 30-30-30 on some Netgears but I didn't find any such warning on the Peacock sticky so I gave it a shot. Putting "Resolved" in the title for now and will post back if problems recur.
