On 3 modems and with firmware (3.100 through to 3.211) I get the message
“No Internet” on the LED Display and also “No Internet Connection! Find new networks to reconnect.” within the LUCI web GUI, however LTE connectivity works and I can surf the web. This does not occur when the router is in repeater mode, just on cellular.
This occurs with the following devices Mudi (GL-E750)
This happens on various carriers and with firmware (3.100 through to 3.211) only on LTE.
