Cannot Connect

Hi all,

I hope anyone can help us ...:)

My 8 yo and I are trying to connect our so much expected EZ-B v4 but haven't succeeded so far.

When looking at the connection script we get the following:

connection failed: system.net.sockets.socketexception (0x80004005): No connection could be made because the target machine actively refused it 192.168.1.1:23.

I haven't found another available port apart from this one, and don't know if I need to change the wifi configuration to enable this one?

Any help will be very much appreciated!

Thank you,

Julian and Sofia

Is that your IP when you have connected to the "EZ-B v4 xx" wireless network? It shouldn't be. The EZ-B should assign the PC an IP address within the 192.168.1.x range. If it isn't you need to check the properties and settings of the PCs WiFi NIC and make sure it is set to Obtain an IP address automatically

Just to add to this conversation I had some trouble initially getting connected to the v4 board when it was configured to connect as a client to my home wifi network

I had initially managed to connect when the board was acting as an AP (the default) but I struggled to find the devices IP when it connected as a client - the device announced it had managed to connect to my network but I couldn't find it to connect - couple of lessons I learned

My pc's are .net developer win8 machines - both had either virtual network adaptors for vms and also for windows phone emulators - the impact here is they appeared first in the list of network adaptors and so when I tried to scan for the ezb the scan dialog the IP range defaults to one if my virtual adaptors ranges and there seems to be no way to change it ?

I had to disable the other adaptors before the scan would start on the correct range

The other thing I din't spot was that I needed to include the ":23" port parameter in the connect box - might need to highlight that in a tutorial?

One thing that would help is when the board boots up and connects as a client it could announce its IP address?

Hope that helps

Make sure your computer doesn't have a static ip setup for it. My ez-b wouldn't work when I had it on.

@Technopro, Not sure if that's good advice on a permanent level. Perhaps for troubleshooting it's a very good idea. I like to remove everything form the system but what I'm trying to get to work when having problems. However Static IP's should make it easier for the router to find and connect to computers and devices. I'm no network guru by a long shot and I do know all computers and OP systems are different. On my setup assigning static IP's to all computers and devices that are associated with my robot and ARC made things run smoother and with quicker start up. Of course you cant assign Static IP's to the EZB until it connects to ARC.

I was having a lot of trouble connecting to two EZB V4's when I first received them. Here's the thread and what I did to get everything working nicely:

@Dave, you are absolutely correct that setting static (or really dhcp permanently assigned) ip addresses to the EZ-B v4 is tje way to go in infrastructure mode long term, but the original poster is still trying to get an initial connection to the ez-b, where a static IP on the laptop in the wrong subnet will make the connection impossible.

I am having the same problem with connecting the ez-b v4 like sofia. boot up, chime, message, and blue light blinks like it should. it shows up on my network tab on my asus windows 8 laptop. refuses to connect. I don't have a static ip setting for the ez-b, and my ipconfig is saying its 192.168.1.1 like normal. firewalls disabled, no antivirus running, just says "cannot connect to this network" everytime i try. i also tried this with my desktop with wireless dongle to no avail. I've read the tutorial on how to connect and browsed most, if not, all of the forum posts that talk about this, as well as watched all of the tutorial videos regarding connetion. none have been able to steer me in the right direction. everything assumes I am able to connect to the ez-b normally.

has someone figured this out? Is there something in my network settings (on both computers) that I haven't disabled/enabled?

thank you. confused confused confused

Can you provide me with a diagnostic report?

Report Link

Additionally, can you answer these questions...

  1. How are you getting an IP address if the wifi is not connecting?

  2. Do you have static IP Addresses set on your network adapters?

  3. By "just says cannot connect to this network", are you referring to the WIFI connection in windows or the EZ-B is verbally telling you?

  4. You are certain AVAST is not installed?

Hi OakMot,

Pitifully I have tried everything that the nice guys here suggested, unsuccessfully. The next step I think (and given you're experiencing the same problem, both Windows 8) I would suggest that we talk to EZ-Robot because it looks like they don't look at this forum at all.

I've sort of given up for now (it's been 4 months since we started trying with my son) but I would love to see this working.

Maybe anyone at EZ-Robot around and eager to help?

Thanks!

Sofia
