Just an update, I backed down my firmware to the latest 376 and the router is rock stable again. Also; I decided to open up my 87R and remove the heatsinks, the thermal tape they used is complete garbage.
I ripped it off and replaced it with thermal paste on all three heatsinks.
Just from the CPU, it was running at 84C normally and since I replaced the thermal tape it is now running at ~70C.
If anyone is running into a heat problem and dont want to go with laptop cooler fans, I recommend replacing the crappy thermal tape.
This is what I am getting with laptop cooler, I wonder if removing the tape would help me at all???
Is it hard to do? Can clips or ?? be broken? Or is it straight forward?
Also can you post a link to some great thermal paste (amazon?)
The only reason I am thinking about doing this, is heat in the summertime for me, and many others. I know once the firmware is great, this router will be the best of the best, now that we know heat with these is a major issue, maybe not at first but if not addressed the router will most likely prematurely fail. At this price we all paid at least for me, I can not throw that kind of money out every year. Especially if I can not sell it as used, in good working order.
admin@RT-AC87R:/tmp/home/root# qcsapi_sockrpc get_temperature
temperature_rfic_external = 0.0
temperature_rfic_internal = 44.7
temperature_bbic_internal = 50.0
admin@RT-AC87R:/tmp/home/root# cat /proc/dmu/temperature
CPU temperature : 57?C
To get this you telnet into the router (I use a mac, in mac open terminal, then type below)
But first you need to go into your router
"Administration"
"System"
"Enable Telnet" to "Yes"
"Apply"
Now commands on computer
telnet "your router ip" ie: telnet 192.168.1.1
when asked type your uses ie: admin
when asked type your router password
use these commands (provided by merlin and or ??, thank you)
For the Quantenna SoC:
qcsapi_sockrpc get_temperature
For the Broadcom CPU:
cat /proc/dmu/temperature
EDIT: My 87 is performing quite well now, for 3 days so far.
I am also leaving Lan 1 jack unused now, after reading about that, not a big deal to me anyway and MAYBE nothing at all.
