question

I have no solution, but nearly the same problem by a customer. I found out, that the time he is offline, the surfstik we are using gives no gateway in his WiFi Settings. We are always connected, but have no full access. The short times we have a gateway in the settings (without changing anything) we also have full access. Have you maybe recognized something like this?

Saldly no chance. The cerbo does not safe any manuell gateway input. And this seems to be the problem. Sometimes (extreme rarely & without any changes bevor) I see the wifi symbol upper left beside the clock and then I see also the gateway adress.

This is a customer configuration. My own cerbo with really the same surfstick makes no problems and is always online.

Hi, I will suggest to make a reset of the CERBO and retry. Eventually add manually the gateway as 192.168.01 (usually, gateway and DNS are the same in this kind of configuration, LTE modems provide such data, but it can also be disabled into the modem parameters).

Hi all,

Can you try with v2.60 and let me know if that works better for you? We have made various improvements in v2.60, released on Monday this week, wrt WiFi stability. More precisely they are improvements concerning recovery from errors.

We're using a network connection manager (Connman) that was very persistent in giving up to reconnect after a while. We worked on it before, but that wasn't enough. And what we did this time is go all the way and remove all definitive error states from the source code, completely. It can no longer give up - never.

For those into the details, here are the changes: https://github.com/victronenergy/meta-victronenergy/commits/master/meta-venus/recipes-connectivity/connman/connman. (the two from 2020 are new in v2.60)

For any issue reporting, please include Venus OS firmware version used.

We're all for and ready to make WiFi as stable as possible. It shouldn't be that all devices in your house work well, but the Victron one doesn't! :-)

Best regards, Matthijs

Just hoocked up a Touch 50 to the cerbo.
and lost my wifi. Also serious problems with cable.
loosing ip adress. Will not update ipadress. No connection to vrm.

if i disconnect the touch restart cerbo. Everything works really good. Both wifi and using ethernet.

my guess is that tje touch is messing up the ip of the cerbo in any way.

also a wild guess. Is that touch is running somekind of software to be able to be functional. This software is doing something to the cerbo.

updated cerbo to latest software. Still NoGo

update to latest release candidate yesterday. Till NoGo

i guess Victron is aware of this and are working their but of to fix it.

happy days folks.

I also have the same issue,

I have an easy solar 2 gx.

The wifi is terrible, its disconnects all the time. The signal shows 45% and the router is like 4m away. Im using ubiquity wifi which works 100%

I have been reading online and there clearly seems to be a big issue with the wifi that Victron is simply not dealing with, Yes we all know wifi is not ethernet. But it should still work. If there is the noise it should re-connect. Mine disconnects and then just doesn't connect again.

One of the big sales points of choosing this unit was the wifi. The modern world is moving towards wifi only setups. We can't run an ethernet cable to this unit.

I would expect better from a high end product and company like Victron.

Just my 2 cents.

I had a similar issue, where the remote console was really slow in scrolling through the menu's and screen refresh was terrible. Sometimes for hours. Even after reboot.

Non of my other devices on the same wifi network where affected, just the victron remote console in my browser.

Other applications running in the same browser were just fine.

Now, I noticed, the wifi network on my router was under heavy load. I reset the Channel occupancy on the router, wifi load dropped, and now victron remote console is running as it should.
