hey.. i used the luci software installer to instal the manager

4

i was watching this video

and everybody using this device doesent use the modemmanager for connection. but NCM!

that is ok.. but i want to have the "MODEM" in LUCI like in the video and my GUI is missing that tab.. what should i do.

Are you sure you have all required packages installed? The post above that I deleted went into this direction and the other deleted post as well.
Double-check if you have the luci-proto-3g and/or luci-proto-modemmanager packages installed.

OK, I just found your other post here: Modem Tab missing - internet working
Please do not post the same question in two different threads! As you've noticed, it's the same people answering anyway! And having to read the same question several times is really annoying.

I suppose, this thread is now actually solved and can be closed?
