Connecting To Two V4 Ezb'S

First question and problem: I think the intent is to be able to connect up to 5 EZB's through ARC. However I've hit a wall trying to connect ARC to two V4 EZB's when they are in AP (Access Point) mode. Using my laptop I've followed directions and connected ARC to the first V4 after establishing a wireless connection through the "Wireless Network Connection" icon on my Win 7 Taskbar. Then when I try to connect wirelessly to the second V4 EZB I lose the wireless connection to the first. My laptop will only let me have more then one wireless connection at a time. What am I missing here?

Second question and problem: With both V4's in Client mode and the Green light blinking (the voice says she's attached to my network), I can only have one EZB powered up at a time and have a successful search of my router for a IP address. If both are powered up and attached to the network ARC cant find an address. Is this normal? I've watched the tutorial several times.

Third Problem: For two nights now after the laptop and robot are powered down the second EZB entry in ARC will not connect to the second EZB board. I have to push the network reset button on EZB and redo the IP search in client mode.

Thanks for going through all the trouble Alan. Sadly though I already had the Never Forget function enabled and had confirmed that both EZB's have been in the DHCP Client List all along. However they both appear as "Unknown" but I can ID them by their Subnet addresses. Mainly because I saw them appear in the list and know what the other devices on the list are.

In ARC I can not manually enter the numbers. I have to run a scan from each EZB slot and click on the address it gives me. The odd thing is that they both show in the list and each tells me they are connected to my network with the green light flashing. The "ONLY" times I was able to get both to connect was after I'd reset them and rescan for them with EZB of when I moved the one to another room.

To manually enter the IP in the connection box;

  1. Click on the box with the IP address in, a blue backgrounded dropdown should appear
  2. Click in the same place you first clicked (i.e. don't select something from the dropdown)
  3. The IP address in the connection box should become highlighted in blue
  4. Type the IP you require.

It sounds to me like it is a signal strength issue. You could put a wireless repeater in the basement right below the router. Wireless signals like going through interior walls much more than floors. These signals travel in a straight line. Going straight through a floor is much easier for these signals than going at drastic angle through a floor. If you take into account the thickness of the floor you are going though when going at a 90 degree angle, instead of say a 45 degree angle, you will see that the signal it far more obstructed when taking the 45 degree angle. Also, then adding in any interior walls, the signal can be very obstructed. Along with this, there may be other things in the way like hvac plumbing or water pipes. This too will limit the available signal.

The way to solve this is either to place a second wired wap (wireless access point) in the basement or use a wireless repeater placed in the optimum location to limit the amount of material between the wireless router and the new wireless repeater. The repeater will then be able to provide adequate wireless signal to the basement because the angles that the signal will be going through the walls will be much closer to 90 degrees.

I will keep monitoring this thread incase you have any questions about this post.

A question I have is how strong is your wireless signal on a smart phone or other device when in different locations in you're basement? If the ez-b is as bandwidth hungry as DJ described, you will need pretty strong signal to get things to work right.

@d.cochran, That's awesome info. Thanks so much for sharing your knowledge. ;) One of my plans is to move the router closer to the robot. B9 being a few hundred pounds make it hard to move the robot closer to the router. Whats that old biblical saying?; If Mohammed cant go to the mountain, bring the mountain to Mohammed?

Anyways, I've got a busy non-robot weekend coming up (Damm- it) so I'll have little time for the big guy and wrestling with this problem. But I'm sure I'll squeeze some in. I'll update with my progress as I move through this. :)

Fearing that the units are interfering with each other and thinking about what Jermie asked about the metal shelf the top EZB is mounted on I thought I'd post a pic of the center support system. As you can see it's made of aluminum plats topped by thick polycarbonate and held together by threaded rods.

So what do you all think? Could this be acting as a big antenna and overpowering the lower EZB?

anything that is metal and the correct length could act as an antenna. More likely though, it could be acting as a shield, blocking some of the signal. Here is an idea. You could place a wifi repeater in the robot and have an external antenna. This would depend on the type of signal you could get in the location of the robot.

Here is a test you could do.

  1. Take a smartphone and connect to your wifi.
  2. Note the signal level you are getting on the smartphone.
  3. Place the smartphone on the robot in the location that you are going to place the ez-b.
  4. Note the signal level you are getting on the smartphone.

Did the signal drop? if so, the structure is blocking the wifi signal. The way around this is to use an external antenna to get the radio to pickup wifi outside of the structure.

Excellent ideas @d.cochran

@Dave I forgot to ask you to try something, you could place a plastic spacer between the EZ-Bs and the shelf that they are mounted on in order to get them more in the air and further away from the aluminum plates.
