question

@PaddyGlenny, without being in front of the unit it's a bit hard to tell, but failure to connect to WiFi (barring a non-compatible wifi dongle, which it sounds like is not the case) is most commonly caused by an incorrect password being entered into the CCGX; since it finds the networks, the dongle is ruled out as the cause of the problem, which largely narrows down the problem to an incorrect wifi password.

I know how aggravating it can be to enter a complex wifi password into the CCGX using its buttons; please be advised that you can connect a USB keyboard to the CCGX to make this process easier.

Please see the CCGX manual, and particularly section 1.6, for more information on internet connectivity.

Once the wifi is successfully connected, you will of course need to manually "add installation" to the client's VRM portal to be able to access the device, but naturally the wifi connection must be correctly established first.

There isn't a factory reset option in the CCGX, but the "reboot" option in Menu>Settings>General>Reboot? may be of assistance; I'd recommend rebooting the device and then, after connecting a USB keyboard if desired, and then re-entering the wifi password for your selected network and I feel certain that you'll be successful in achieving connection.

Justin, whereas I appreciate your taking the time and trouble to answer, the password is not the issue. You are right that it's a pain in the ass entering a password, especially a long one such as both these networks have, but I have tried over and over and even had the client enter it and had him watch over my shoulder while I did it for the hundredth time and confirm it was entered correctly. I re-entered it on my phone to confirm and the phone gets connected immediately. And you know why I've done it so many times? Because the device won't remember the password.

I select IP configuration: automatic (although I've entered the ip address manually as well).

Then I enter the password.

Then I select "save changes" by pressing the centre button.

Then, but only if I have rebooted the unit, it briefly shows "connecting" before showing "disconnected".

If I didn't reboot, it doesn't even try to reconnect, just stays at "disconnected".

If I exit the screen and come back, the "ip configuration" is back at "unknown" and the password has disappeared.

And I can find no way to get it to forget the networks, to allow me to re-enter the info...but you might be onto something inasmuch as the first time I entered the password, I entered it incorrectly.....is it possible it is refusing to forget that initial password, I wonder?

Whatever, it is a bloody unsatisfactory piece of kit. The client has bought almost €10,000 worth of Victron components, all let down by a distributor who takes 72 hrs to answer an email and a ten cent item like this ccgx that amazingly cost €525!!! That's about $700, and far off the price of an i-phone 10.....but at least with a smart phone you get the option to do a factory reset.

Hi @PaddyGlenny Sorry to see you are still having an issue. In your other post on the same issue, the many walls and distance from router was a possible limiting factor. Another possible way of testing the device's signal strength is plugging it into a laptop at the same location and check it's signal strength. As a last resort powerline plugs may be a way to offer a quick reliable wired connection.

Hi @PaddyGlenny

You're getting good answers from the community here, so I saw no reason to chime in.

I'm sorry that your distributor is non-responsive, I hope you have another distributor you can choose to go to that does give the mandatory support. For complaints about distributors you can go to the Victron sales agent for your regio:

As an installer I assume you've had training?

In any Victron training it is emphasized that for a reliable and stable connection, a network cable is -always- the first choice. Using wifi leads to exactly the problems you describe here.
