Thanks, but if Ethernet means a wired connection then it's a no go.  This application has to be wireless.

Nobody mentioned anything about wires ...

When it shows the list of Networks, the MiFi shows the signal strength bars, and the Yun shows the same signal strength bars but with a little shield with a ! in the shield above the bars.  Is that an indicator?  This is on Windows 8.0.

I don't run MS Windows 8, but that shield icon must be there for some reason; does any text pop up when you hover over it? Can you right-click on the network line and get its properties?

kind regards,

When you're working with Yun's own wifi, your mifi router or whatever other thing is around you has nothing to do with you. It's only your laptop and your yun

That's the reason why I suggested to switch the entire thing off; I don't believe that a fresh out of th e box Yun (or decently reset) can cause so much trouble; it has to have something to do with the laptop.

kind regards,

On my work laptop I got different responses when I ping'ed.  Usually just a "general failure" or "Request Timed Out", but one time I got a "Destination Host Unreachable" 3 times, then a "Request Timed Out" the 4th time.  It doesn't seem to matter if I've got my MiFi connected or not.

That's one of the lower OSI layers, i.e. depending on, say, humidity, the radio transmission/receiving layer might be goofy; it has nothing to do with your problem.

At my work laptop with the MiFi off I did a diagnostic on the Connection and got a message that said: "Wireless Network Connection" doesn't have a valid IP configuration. It also said that my laptop had a proper configuration.  It also said it detected my Yun.   

Hm, to me it looks like your company is trying to block other networks from being connected; what should be invalid about the IPv4 192.168.240.1? If this happened to me I'd feel the irresistable urge to completely reinstall the OS on that laptop; but your company probably wouldn't like it ;-)

A silly idea: after the Yun has booted, switch off your 'Mifi' network/router; now it's only your laptop and that Yun network with the Yun itself as an access point; can you connect to it now? If so, switch on your router again and see if the connection stays alive.

kind regards,

After you made a connection (with that other laptop), can you open its web interface (http://192.168.240.1) with a browser?

Doing a laptop Restart didn't help either. 

I'm sure it's something basic on my laptop, but I haven't a clue what.  Some configuration issue?

Strange ... so your laptop can 'see' the Arduino network but can't connect to it; the encryption used on other networks have nothing to do with it (WPA, WEP etc.) and the Arduino network is completely 'open'; the IPv4 address is 192.168.240.1 (after a reset); the silly thing is that it works for me without problems (using url http://192.168.240.1 in my browser after connecting to that network). My guess would also be that it's something in your laptop that forbids a connection (one way or another). Can you ping it from your laptop? (open a command line interface and issue a 'ping 192.168.240.1')

kind regards,

I don't know anything about Kaspersky but I do know that I only trust that stuff as far as I can throw a rock at it; can you (temporalily) switch that thing off and see what happens? (you won't be swamped with viruses and spam all of a sudden because you also have a firewall in your router ;-)

kind regards,

This is a very simple view of it all (at least, this is the way I did it) - when your Yun has booted for the first time (and it has booted, because you saw that large 'Linino' logo), it has created its own network. From your MS Windows box you should see it in a list of available networks. Click it and make your box connect to it; next point your browser to the url http://192.168.240.1; can you make it that far?

It's an old fashioned hacking session ;-)

I simply love it.

one comment (not important) :

"/dev/mtdbblock3" is in jffs2 format and jffs2 is compressed, then dumpfile is no longer readable text.


Can it be gunzipped? If so, a line as:

dd if=/dev/mtdbblock3 | zcat > /mnt/sda1/dumpfile

might do the trick. (I know next to nothing about OpenWRT's filing systems trickery)

kind regards,

You could try this:

dd if=/dev/mtdbblock3 of=/mnt/sda1/dumpfile

This'll create a file named 'dumpfile'. Although it'd contain a lot of binary rubbish, the vi editor can still handle it; you'll spot the readable text parts in it and you have to remove the rest of it (using vi). It's an old fashioned hacking session ;-)

kind regards,

Jos

If all else fails, you might try a dd from that partition and write it somewhere else (on /mnt/sda1 perhaps?) You can easily recognize that python text among all the binary gibberish and if your original filing system wasn't too fragmented, you'd be able to retrieve your file (or most of it).

Ok, don't use the -Xmx flag to make the heap larger then, but your Yun won't hit the swap space unless you fill it up with other memory consuming processes ... (-Xmx32M makes your heap large enough for substantial Java programs while it still doesn't need that (slow) swap space).

Jos

Trying to turn on swap space is useless, because by default jamvm claims only 1MB for its maximum heap size (see the -X option for details), while (normally) Linux doesn't hit its swap space with that small amount of memory; that bus error has another cause (I run jamvm with 40MB heap space fine).

kind regards,

Jos

ps. it -Xmx, not -Xms (that's the stack size limit)
