Laptop Connection Questions

I am on a hp laptop running windows 7 with avast disabled. When I turn on my EZB it says that it has successfully connected to my network and when i try to connect to my EZB in client mode it connects and then disconnects after a few seconds, I then get this message:

EZB 0: EZB 1: EZB 2: EZB 3: EZB 4: Attempting connection on 192.168.1.1:23 Connection Failed: System.TimeoutException: The operation has timed out. at EZ_B.EZB.Connect(String hostname, Int32 baudRate) Disconnected Attempting connection on 192.168.1.5:23 Comm Err: System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.IO.Stream.ReadByte() at EZ_B.EZB.drdP31fe7H(Int32 , Byte[] cmdData) BbytesToExpect: 1 U Received: Disconnected Connection Failed: System.Exception: Controller Not Responding at EZ_B.EZB.g0KPD37NHh() at EZ_B.EZB.Connect(String hostname, Int32 baudRate) Disconnected

The EZB can connect when I try it on my dad's computer.

Any help would be great.

If you are able, post all the specifications about your computer.

Follow the first method and post what step 3 shows(if your comfortable with what it shows) by pressing the print screen key on your keyboard, opening the program called paint, pasting the image into paint, and saving it to a location on your hard drive you will remember. Then post it here.

@Maze, pepper has submitted a diagnostic report, which we have already reviewed. Unless pepper wishes to post the diagnostic report public, it currently resides in a private repository.

Hi DJ ,

Any idea when you might be able to create the connection diagnostic tool, as i have tried all suggestions with no success.

Thanks.

There is an ARC update scheduled for tomorrow, which will include a connection diagnostic option.

Okay, thanks.

The issue is that the computer is not connected to the EZ-B v4 over WiFi. The computer appears to be connected to your local router WiFi. Ironically, the local router WiFi also has the ip address of 192.168.1.1, which isn't uncommon - as it's a common private ip address network.

What you will have to do is connect to the EZ-B v4 WiFi network. If you are indeed attempting a connection to the EZ-B v4 WiFi network, do you receive an error in the WiFi connection attempt? For example, does it read "Unable to connect to network"?

First, the diagnostic report does detail that your home network is 192.168.1.0/24...

[feature] ICMP Response Testing to see if the network is the same ip subnet as the ez-b. Ping 192.168.1.1 replied Success took 1 [/feature]

Also, the wifi interface also states this...

[feature] DefaultIPGateway = 192.168.1.1 Description = Broadcom 4313GN 802.11b/g/n 1x1 Wi-Fi Adapter IPAddress = 192.168.1.13 [/feature]

This is not an issue to have the same network - unless the WiFi connection attempt is being made on the second WiFi adapter, because your computer seems to have 2 wifi adapters.

[feature] D-Link DWA-140 RangeBooster N USB Adapter(rev.B2) and Broadcom 4313GN 802.11b/g/n 1x1 Wi-Fi Adapter [/feature]

What i recommend is either...

  1. disconnect the D-Link Range Booster USB Adapter and connect to the EZ-B with the built-in broadcom 4313

  2. or, if you prefer to use the D-Link, disable the Broadcom adapter. To disable an adapter, it can be done in the device manager or network control panel.

Your computer will be unable to connect to both your home network (192.168.1.0/24) and the EZ-B (192.168.1.0/24) at the same time. This is because they both have the same network address.

To dig deeper into what the diagnostic report demonstrates, we can examine the connection transaction details...

[feature] 15/12/2015 18:13:32 Attempting connection on 192.168.1.1:23 15/12/2015 18:13:35 Connection Failed: System.TimeoutException: The operation has timed out. at EZ_B.EZB.Connect(String hostname, Int32 baudRate) 15/12/2015 18:13:35 Disconnected 15/12/2015 18:13:53 Attempting connection on 192.168.1.1:23 15/12/2015 18:13:53 Sending: 85 15/12/2015 18:13:59 Comm Err: System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. 15/12/2015 18:13:59 BytesToExpect: 1 15/12/2015 18:13:59 U Received: 15/12/2015 18:13:59 Disconnected 15/12/2015 18:13:59 Connection Failed: System.Exception: Controller Not Responding [/feature]

Okay, so what is happening here? Well, what this shows is that there is indeed a network connection to 192.168.1.0/24 network, which is your home router. The router is accepting a TCP client connection on port 23 from the computer. At that time, ARC transmits the "Greeting" command, which is 0x55 (ascii: 85) character. Now ARC will wait for 5 seconds for a response. In this log above, the response is never received. This is because the device in which ARC is connected is not an EZ-B v4.

To ensure there is an understanding of how to connect to the EZ-B v4 over WiFi, and to report if any errors are displayed (such as Unable to connect to network). Please be reminded that the error I am referring to would be displayed in the WiFi Connection not the ARC Software.

Hi DJ,

I have sent 3 diagnostic reports:

  1. HP Pavilion dv6 Laptop (my laptop) with internal Wi-fi connection adapter

  2. HP Pavilion dv6 Laptop (my laptop) with external USB d-link adapter.

When I connect to the EZ-B from my HP Pavilion laptop with either Wi-Fi adapters I can log on to it's IP address and run the commands in the diagnostic tab (making the noises and centering the servos), but i can't connect to it through the ARC software.

  1. Acer Aspire E 15 with internal Wi-fi connection adapter.

The third was from my brother's Acer Aspire laptop which connects to the EZ-B with no problems as does my fathers desktop PC.
