The RPi has a USB to Ethernet Adaptor on the board, so not feasible.http://www.microchip.com/wwwproducts/De ... ct=LAN9514sprudeldude wrote:Hi,
I recently bought a Raspberry Pi model B+.
I wanted to enable the Wake on lan function to it.
Can someone give me a tutorial how to install it and use it ?
Many thanks !
Which is not the reason it can't be done. That adaptor does have a WOL capability - however it is not enabled and as it is not connected to anything on the Pi, there is no point in enabling it.fruitoftheloom wrote: The RPi has a USB to Ethernet Adaptor on the board

Why leaving it on for 24 / 24 if there might be solution for turning it remotly on and off ?DougieLawson wrote:What's the problem with leaving your Raspberry Pis running 24*365? A RPi B+ uses 200mA while idle, an A+ uses 100mA while idle.

Or isn't there non solution for this ?
Code: Select all
I take it they aren't available on some headers, pads or pins either then?rpdom wrote:...

I'm on this side of the fence and just checking optionsDougieLawson wrote:.. trying to maximise battery power.
Right - a bare bone RPi won't ever have WOL - I'm with you, no worries.DougieLawson wrote:What part of "it can never work" are you struggling with?
A Pi power supply switched on by a WOL packet is entirely possible.JoanTheSpark wrote:Where is the problem with that solution?
JoanTheSpark wrote:Again, I'm on batteries somewhere outdoors (it might have slipped your observation, but I mentioned it up there) - I don't have the option of plentiful energy, 10W 24/7 is out of the question.
The RPi has the task of booting, doing some stuff and then going back to power off. A dual timer RTC is taking care of that (example: NXP PCF85263A).
As a future option I would like to be able to wake the RPi via Ethernet any time I want (thus the exploring I'm doing at the moment). The Ethernet might have PoE or not, but I can't run it 24/7 as the energy for that is not available - especially when you have a couple of these units running.
Is my position understood now?
Back on topic.. I think the solution up there with the additional PHY needs a LAN switcher, as you can't have 3 PHYs on the same 'cable'. There seem to be units made for such a purpose for notebook docks.
Example would be this one here http://www.ti.com/lit/ds/symlink/ts3l110.pdf
So I think I'm able to do this.
At the moment I'm just putting the circuit/hardware together.. software is another chapter I guess
Worst case power draw estimate for a strap-on-WoL at the moment (~ 80 mW):
- KSZ8091 in EEE mode 3.3 V / 23 mA
- TS3L110 3.3 V / 0.7 mA
PS: I know that the A+ uses 100 mA when idle (vs the 200 mA of the B+), but it doesn't come with Ethernet, so that is moot.

No. Well, they might have included it, but that seems unlikely as it's not needed in its primary educational role, the Pi is a product designed to keep its costs low, and it's not a necessary feature. That doesn't mean it wouldn't be a desirable feature for some people with some use cases.DougieLawson wrote:don't you think the RPF might have included it on some of the existing Raspberries.
Good for you. But sometimes Pi's do crash, or users do something which causes them to lock up, or shutdown, and having a remote means of wake-up or re-boot is handy to have.DougieLawson wrote:I have ten raspberries running 24/365.25 and they don't crash.
This would totally work. It's a small investment and you would make your ROI within 3 to 5 years.fruitoftheloom wrote:
