question

Hi @Jack Beach

What you may be up against here is the one-at-a-time ethernet/wifi access. Usually possible to connect concurrently, but ethernet gets priority and wifi only kicks in when ethernet is down. (This may have changed a little in the detail over the years.)

Try pulling the cable, and see if you can connect wifi then. Be patient, it may take a few minutes to sort itself.

If that doesn't work, try rebooting the GX. If you need the cable to do that, pull it as soon as it accepts the reboot instruction. It should awaken eager for a connection.

If that doesn't work, then it may be the signal strength, 54% isn't really that great. But let's see..

I have the same problem with MultiPlus-II GX. If your multi managed to connect via wifi at least once then your wifi settings have been saved. While multi is on, push the reset button to restart the GX. This will clear a stuck wifi loop and connect once restarted. I have to do the reset at least once a day to fix the wifi connection.

Planning to update firmware to 501 soon, hope that fixes it.

I have an easysolar 2 and I have the same problem. I do not think it has anything to do with multiplus firmware, I have 501 and latest GX firmware. In the end I got a tp-link re605x wifi repeater and connected the ethernet of the repeater to the ethernet of the easysolar 2. The repeater is connected by wifi 5ghz to the rest of the wifi network. I had no issues with it connected this way.

The wifi in the GX devices is just so bad....

Please forgive the potential silliness of this answer, but do make sure the separate WiFi antenna is screwed into the top left corner of the MPii - they can connect (albeit rather poorly) to strong WiFi networks without this, so it is easy to forget. The GX on an MPii is a real pig to configure on a remote terminal if the WiFi signal is weak, which may lead to the kids learning some new curse-words at home.

Also have a look on your router (or range extender) whether perhaps the access point's range setting is not at maximum strength. If you don't already have one, consider adding a WiFi range extender (on a backed-up supply) - it can be an easier solution than running ethernet cables everywhere.

In general, the WiFi setup on Venus is not brilliant, the ppl at @Victron may wish to take note of. One particular clanger is that the WiFi password field is rather short, so one might end up having to change one's WiFi network password (an awkward piglet) to accommodate Victron's laziest programmer or set up a second (guest) SSID on the home network just for the MPii.
