Raspberry PI 3 Dead

As per Shabaz's comment  you will definately need the latest release of  Rasbian (Download it and check the checksum!!) , program this onto a known good SDcard then verify the contents.

I realise it's frustrating and boring but unfortunately it's the only way to reasonably check each part of the overall system rather than just switching it on and the thing not working .

As usual More questions than answers... lets here back from you when you have done that ...Cheers

Well guys,  I've got it running somewhat.  Here are the issues I have found.

the wi-fi is flakey.  Pings from my Mac to the Pi3 are all over the place from 5 ms to 125 ms.   and it drops out often, meaning I have to sign back in to the router.

trying use Tightvncserver is also problematic.  Sometimes trying to connect will cause the wi-fi on the PI3 to  drop out.

None of my other PI's are like this.

What happens if you ping from the Pi to the router, does that temporarily fix the problem?

i.e. when you observe that the pi is no longer pingable from the Mac, then if you ping from the pi to the router, are you then able to ping from the Mac to the Pi again?

Try this to update firmware to latest level:

1. sudo apt-get install rpi-update     (Maybe already there)
2. sudo rpi-update

I've done all this and I'm still having issues with the wi-fi dropping out.

I've tried pinging both ways to and from the Mac and the PI3.  Still get way too large of times.

Also, when I try to ping from the PI3 I get the following:

ping:  icmp open socket:  Operation not permitted

I have to go to sudo ping to make it work.  I've never seen this before on any of my other PI's.

It is difficult to help if you are you not more precise with your problem description unfortunately. You have mentioned WiFi 'dropping out' what does this mean? Lost packets? Is it intermittent, and once packets begin to be dropped are all packets dropped or does it recover? You also mention round trip times being high. Is that a separate issue, or is this what you meant by 'dropping out'?

Sorry that we don't speak the same dialect of English.  By dropping out, meaning, that the WI-FI connection is lost.  It will do this for several seconds at a time.  Sometimes requiring to reconnect the wi-fi at the panel in the top left of the screen.

There is some sort of issue here, as the ping times should be less than 10 mS and no packet loss.

One question I would ask... do you folks replying to this post have a PI 3 running.  If not say so.  I have several PI 2's and do not have such issues.

The environment is very important. how far are the machine and router? walls in between. The power of the radio signal? Do you have many other AP's nearby? I know how to try some things.
