Ez-B V4 Won't Connect To Wifi

Really hope someone can help.

I am trying to connect my EZ-B v4 to my laptop but having no luck so far. In brief, the v4 is found on my available network list, but when I click "connect" it comes up with the following...

In addition to the post above, I had a look at the windows network diagnostics.

I also forgot to mention, I have reset the v4, and restarted the laptop too, but to no avail.
your ip address looks wierd. the last should be one.one but in numbers. it looks like it is lower case L.lower case L, or upper case i.upper case i.

sorry, I see that you saw that already. I will step out again.
When I tried on my android ... my android gave me the address for my ezb4 not Check your connection on your iPhone to see if the address is different....

Ok, tried again and finally got it to work on my android using was able to bring up the ezb4 webserver on my Android Galaxy s3
Just wanted to mention that it works on my iPhone5s

Edit: just in case my response wasn't seen, please change the colon location
Cycle the power on your ezb and connect again to your ezb4 with your iPhone. Keep trying using It took a couple of times but I finally was able to bring up the ezb4 webserver via my Galaxy S3 web browser....
Now use the server to flip the ezb4 into client mode... It will reboot and the led will start flashing green... Congrats you are in client mode... Now open ARC and use the scan tool in the connection control (looks like a mini cell tower) to locate your ezb....

Richard my friend, you have saved me from a nervous breakdown.

Thank you so much for your help with this, and thanks to the others too. If I'm ever across the pond, I owe you a few beers.

Steve. ;)
@Steve.... Awesome.... Enjoy.... Now maybe you can help Nomad... he has the same problem you had.... One of these days I will eventually head across the pond to see England and France.... I will take you up on your offer... Once we get good and wrecked we can head over to Rich's house and pee in his garden...:P

:P Sounds like a plan Richard.

I have to ask though for future reference, any thoughts to why the laptop and v4 wouldn't connect ad-hoc? I'm not to bothered for now as I wanted it in client mode anyway for Pandorabots, but it would be nice to know why I had the problems that I did?
@Steve.gibb5 we have had a few people unable to connect with HP computers in particular, we are still investigating the issue. It looks like it might be that a WiFi driver update is required. Some users have got around it with a $10-$15 USB WiFi dongle.
Jeremie, forgive me if this is in the spec sheet, but I am posting from my phone. What protocol is the EZ-B? G, N, ac? 2.4ghz or 5ghz?

My work laptop (a fairly new HP laptop) has trouble with 2.4 ghz when there is a 5ghz signal visible. I haven't spent much time investigating it, but noticed it when I got a new 5ghz rrouter but wanted to test my 2.4ghz ghz guest network.

No prob, the EZ-Bv4 WiFi is 2.402GHz to 2480GHz b/g/n.

Ok, good to know Jeremie.

Funnily enough, throughout my problem solving today, one of the things I tried was updating my wireless driver, but had a message back saying it was already up to date. Now I know how to set it up now I might try connecting ad-hoc again to see if it works. I might consider a cheap wifi dongle for scripting, testing ect for the time being.

FYI for your investigation, my laptop as mentioned before is a HP650 business end notebook which is coming up to 2 years old now, and has a Ralink RT5390R 802.11b/g/n 1x1 Wi-Fi network adapter. I got to the point where all my firewalls were disabled and anti virus uninstalled as you suggested. I hope this info helps you guys and hope you manage to find a solution.

Thanks for your help.

Steve ;)
Thank you very much Steve, we appreciate the info!
Hi all. I have a similar challenge, except I want to stay in ad hoc mode! We want to take the bots out of the lab and onto the streets, ala Spider Dog (check out the YouTube video), so we want to control the bots without routers i.e. ad hoc.

We have 2 laptops that connect ad hoc and 3 desktops that will not. Yeah, so laptops; what's the problem? Well, we'd like to know what causes the issue so we know we could use any laptop to control the bots.

If the bot's wifi circuitry is not responding to all ad hoc requests, is there a possibility other circuitry might resolve this random issue? If it's the wifi dongle, what's a make/model that people know work that we might use as the main connection point for any laptop? I'm also wondering if there could be a problem with Windows security settings or some other configuration issue that's causing this to happen.

We taking to the streets! Any help figuring this one out will be appreciated.
