Re: Using Both (eth0 & wlan0) Interfaces

Look at the top of the /etc/network/interfaces file and you'll see these instructions. # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' Negative. OP looks to be wheezy. OP, what do you mean simultaneously? You want it to ...

Re: rPi3 & hostapd

The monitor mode error is normal (no support for it "yet" with current drivers). With debugging (-d) enabled, you'd then see "nl80211: Driver does not support monitor interface type - try to run without it" Like you've noticed, the AP does come up. However, you run out of entropy for encryption, whi...

Re: Raspberry Pi 3 - AP/Client

pi3's wifi does ap and client simultaneously just fine. Can't speak about performance since I'm not using it in a bandwidth intensive application. However, if the client's ap changes channels, it's not easy to deal with.

Re: Micro SD: Speed vs. Size?

The evo and evo+ are the only cards to consider, and they're priced as cheap as any. Most benchmarks and all advertising showcase sequential performance, but the evo series are in a league of its own when it comes to 4k random read/writes (read: use as an OS medium). There are a few other cards that...

Re: Raspbian's new insanely bad design decision: DHCP Static

I'm running into at least two issues. 1. I have services that rely on a static ip. Unfortunately, dhcpcd does not provide this ip in time, and I'm not interested in going out of my way to better manage when these services are brought up / restarted. So I still need to define the iface as static and ...

Mine passed N=8000 with +1 (8-hour loop). However, just tested N=10000 and it locked up on the first pass. So far so good with +2. :roll:

Re: Pi 3 Overheating Issue?

1300 MHz . never hit 80C ( CPU throttling threshold), so never throttled down. 76C is as high as it went. It seems that you have a particularly lucky CPU in your Pi 3. Some seem to overheat and malfunction at stock frequencies so over clocking isn't possible. It would be very interesting if you cou...

Just use the dtparam:

Re: Pi3 incorrect results under load (possibly heat related)

Just tested 10 runs with +1. All passed. However, at stock voltage, the system locks up hard after about half a minute, so I'm tempted to run +2 just in case. Seeing a 4'c difference in load temps between +1 and +2.

Looks like mine is stable at stock voltage. -4 doesn't boot. -2 locks up after a second, and -1 after about a minute. With a small heatsink and fan, temps max out around 52'c.

Re: [RESOLVED] Pi3 WiFi stopped working

Thanks! Looks like sd_overclock is now supported on the rpi3.

With dtparam=sd_overclock=100, I'm seeing 40mb/s read, 20mb/s write :)

FWIW: looks like the samsung evo can handle 107 (core 425). 1:1 seq read gain with clock increase

Or 6 if 1.5x cores is optimal
