Hello,
After unsuccessfully trying the UART WIFI suggested by this website, mainly because of power issues though I could have it to work and run for a little while, I tried another UART WIFI which seems much, much, much more reliable and user friendly since it has its own AP mode which allows you to configure it through web interface directly (you do not need to connect it to USB TTL module) and a quite efficient factory restoration process in case you input the wrong settings.
The model hardware name on Amazon is "Embedded Wifi To Serial Module RS232UART WIFI Board Module External Antenna"
I can get a connexion to EZB using both methods : typing directly the IP address + port into EZBuilder's connection or through serial emulation.
However, when I use serial emulation (HW virtual serial port) I get a repeating message such as : "Disgard incoming buffer (This should never happen)"
And if I connect through IP address directly I get something really weird : it says that I have to upgrade the EZBoard firmware and, most of all, it shows different versions numbers : 24.x , 14, 17...
Here is the full debug report in cas God (DJ) took a look at it. I remember someone had ordered the same device so I'm posting this in case he found the proper settings. I set the module to 9600 bauds, TCP server mode. Let me know if you need more details.
Here is the debug report.

For some reason that I still have to find out (and thanks to you I got that there's something to find out) my current network config doesn't allow me to do it that way. However the fact that I can connect through WAN IP with HW from outside is a sign that I might have had two problems, and one fixed for now, one on my network config and one coming from my ARC installation. I remembered messing up some days ago with some windows services and this could also be the cause of my other pb (JPEG stream error message that we discussed recently). On the other hand I also think it's actually more likely to be another network / router issue since this happens on all my computers. I'll look into once I have the time to do so.
@Alan : at least you know that you can connect with the module we had gotten from Amazon, now.
Thanks for your help, again;
I'd say it's a network issue, no doubt something to do with the router (it usually is, routers can be a nightmare depending on what it is). With the cameras do you use UPNP or have you manually set up the port forwarding?
Networking can be an absolute nightmare on some hardware. I made a point of changing the router my ISP gave me for something much better (I highly recommend something that can run DD-WRT firmware - Buffalo routers now come with this as standard). That said, it may be due to a VPN, I tend to avoid VPNs when possible
Based on this discussion, I uninstalled Hamachi VPN (which I virtually never use anymore anyway), and it appears to have resolved a problem I have been having on my Windows 2003 server where any internet downloads were acting like it is on dial-up speeds even though I have 25 mbs FIOS. Other things besides downloads worked fine. I could even stream decent video over RDP from it.

@Alan : Have you tried to hard reset it ? I personally did it by hooking it up to an arduino board with ethernet shield and an I/O switch program accessed in browser. I could not hard reset it using logical signal from EZBoard. If my memory is good it worked only while I sent low signal for little more than 1 second to the nload pin DURING BOOT UP and then returned to high signal. But I also remember having to mess up a little bit with it before it kicked in. one Other thing (I need to double check on that but I'm almost sure) : the connection worked only by connecting TXD to TXD and RXD to RXD on the EZBoard...

I have tried setting the IP on the computer but could not make any connection.
I would really appreciate a full set of screenshots so that I might easily and quickly find the issue.
Use the doc named USR-WIFI232-X-V4-en.pdf in the cd-rom provided with the device. It shows all the screenshots you need.
Best,

I did miss something... I neglected to change mode to STA.
I can confirm it works perfectly.
I think I am the 3rd person to confirm that this UART WIFI module works with the EZB.
I have purchased this unit from EBAY for $32:

Thanks elfege! and thank you Robot-Doc for the HW serial port settings.
But that was not my issue. I could not connect to the unit once it was connected to my network... and the issue was that I did not switch it to STA and kept it on AP.
Once it was on STA I could easily connect to it. When I saw an error I tried switching between the RX and TX.
