How does one turn off WiFi on a 272

OK, same question about 272 Bluetooth.

Setting the Bluetooth input <Enabled> setting to 'No' does NOT turn off Bluetooth.

How about doing a power cycle after turning wireless off and before reconnecting the LAN?

I never put the aerials onto my 272: that is another way of making sure there isn't a signal being broadcast from your 272.

Hi David, I tried both of those!

Even without the antennae, both Bluetooth and WiFi are generating enough signal strength to achieve device connection!
The WiFi signal (Naim.a) varies from about -40dBm to -30dBm.

Ok so my conclusion is that your 272 isn't behaving itself properly and when that happens, a reset to factory settings usually sorts it out. It's a bit of a fag, because you will have to set everything how you want it, but I guarantee the wifi and BT will be off!

good luck

OK, thanks I'll try that (as you say, a nuisance which is why I asked first in case anyone had any bright ideas or knew that this was normal).

Didn't work

Bluetooth <Enabled> is set to Off, but it's still available on the list of available devices - ergo the Bluetooth transceiver is still active.

Network connection is set to wired, but it still creates a WiFi hot-spot called Naim.a.

What WiFi signal monitor are you using ??   I scan my wifi & can see my NDX ethernet connected & wifi off.     Is it just broadcasting as available - like 'hi'  'bonjour'  'I'm here'.    Does 272 need to talk to the wireless world to play with Naim app

It shouldn't be putting out an independent WiFi side channel to talk to the Naim app, it should use the WAP on the wireless network.  The NDX shouldn't be doing it either - the bonjour message should go via the wired connection.

What WiFi signal monitor are you using ??   

I should have a chat with Phil at Naim because I don't understand why it's doing that at all.

I'm using the WiFi adapters built into my tablet and my 'phones (two different ones, 3 different manufacturers).

Relax and play some music, life's too short to bother 

Apart from the fact that I'm trying to trace the source of 2.4GHz interference that keeps re-starting my PC up to 10 times a day as it's costing me by increasing my electricity bill and killing my PC.

It's worth a chat with Phil, the classic streamers switch off the wifi radio when the Ethernet link comes up.. I'd be rather surprised if the N272 isn't supposed to do the same

If that is so Simon,  what am I seeing on my wifi scan ??  I see what I would expect to see but I also see my NDX ethernet connected & not doing anything & also NAS & its hibernating.     I've alsways assumed its broadcasting a 'bonjour' type message

Mike for the wifi and the Ethernet link to be on at the same time, they would need different IP4 addresses, and careful design with most likely  the use of Spanning Tree Protocol to stop network loops.  I have not seen such capability from the NDX.

On my NDX my wifi is disabled as my Ethernet link is active, and all responses to Bonjour and UPnP discovery messages are via the Ethernet MAC address and associated IP address .

if I log into my streamer I see the following which confirms my radio is disabled

Connection Status: connected, BSS
Signal Strength: not available
Wireless Channel: not available
Firmware Date: 2016-03-15

What are you looking at on the Wifi? Possibly the Naim app responding to the media streamer and streamer multicast discovery responses?

Simon

I see the same Simon,  same IP4 address & naim log.  thats why I asked & is Huge seeing the same.

Mike indeed.

Huge can you expand further what you mean by

>Look at my WiFi signal monitor and Naim.a is still being broadcast.

What signal are you looking at? Is it an SSID beacon? How do you know its coming from the streamer. Are you seeing two IP addresses and/or Mac addresses from the streamer? What does the streamer say when you connect using a web browser.. does it indicate the wireless radio is active?

That should help narrow it down

If you mean it's waking up from sleep then you can override the cause, use powercfg command to configure the relevant override

I doubt it's adding much to your electricity bill nor will it harm to your PC, perhaps worth stopping the unnecessary restarts though

Yes it's waking from sleep.

powercfg is totally useless,  powercfg reports a zero length list of devices that woke the computer!   i.e the OS doesn't know what woke it!

If I remove the 2.4GHz wireless receiver it doesn't wake inappropriately (and I've tried 4 different ones - so the cause is RF interference.  The mouse receivers are all ridiculously over sensitive: With the receiver(s) wrapped in aluminium foil the mouse still works from 4m away.  One receiver was immune, unfortunately that one permanently lost connection with the mouse on 30% of restarts (needed reboot).

If I use a wired mouse the wire keeps getting hung up on things on my desk and that makes is pretty much useless for controlling the computer.

The constant restarts and shutdowns are killing the fan on the graphics card - when that fails the likely current surge will sometimes take out the motherboard and quite possibly also the power supply (in the worst case, that can then cascade on to other devices).

What's the use of LED lamps when 30% (about 50% at night) of the time the computer is doing nothing and taking 220W.
Most of the restarts are at night (but not always).

I've tried switching off all the 2.4GHz devices in the house except the 272, so it's either that or aliens using high powered transceivers on their flying saucers!

Why not just turn the computer off at night if you're not using it ?

Because it's set for hybrid sleep, so I can continue working in the morning.

Simon,

I also get

But there's also a wireless SSID called Naim.a with a MAC different address (one that I can't find elsewhere on the network).  Curiously this one disappears when I turn on the network WAP.

The Bluetooth is also still transmitting at 2.4GHz even when the input is not enabled.

And this all disappears if you turn off the 272?

You don't have a neighbour with Naim do you?......

David

Neighbours don't have any Naims and I can see their WAP at -60dBm (30dB below mine which is itself set to -20dB).

According to powercfg, the ONLY thing witch supports waking the computer from sleep is the mouse.  As the mouse it turned off (physically) it must be interference being picked up at the wireless transceiver.

As it seems to be impossible to turn WiFi and Bluetooth off on the 272 I'm going to fit the antennae - that way the transceivers will have the correct load and this should reduce distortion (and hence reduce output crap modulating the 2.4GHz band).
