When an Ewon is using a worldwide provider SIM card (Like 1nce for example) or using roaming because it is installed in a foreign country, you may have to select the right local operator to make the connection work.
For this, use the Operator selection combo box in the Ewon Web interface to select the Operator (with better bandwidth or lower costs).
This option is located in the Modem page (Setup→System→Communication→Networking→Internet Connection→Modem →Interface), you can choose the Operator among the list of operators found by the modem.
In case of connection instability, it may help to force the network mode on 2G, 3G or 4G.
In the Modem page (Setup→System→Communication→Networking→Internet Connection→Modem →Interface), you can select the Wireless Network among the list of 2G, 3G or 4G if available.
With the Cosy, it is a little more complex to select the operator, as you firstly need to retrieve the list of available operator. They are several ways to do this, but here I will explain how to do this without usage of additional software.
To retrieve the list of operator, use this URL and replace the IP by the IP of your Cosy:
http://192.168.120.233/rcgi.bin/ParamForm?AST_Param=$dtES$ftH$fn
So, you will have the sysinfo list, in this list find the GSM information
Especially the GsmOperList
In this example, we have 3 operators available, and you can see their id
When you have selected the operator, let's imagine this
Go in (Setup→System→Storage→Edit COM)
In search field, set GSM
when you see GsmOpid, set the previously retrieved value
save
Reboot the Cosy
Depending on the modem, the parameter WirelessNet could take the value:
Go in (Setup→System→Storage→Edit COM)
In search field, set Wireless
when you see WirelessNet, set the mode 0, 1, 2 or 3
Save
Reboot the Cosy
