In new NetworkManager has a regressio, which does not allow to choose network type. Anyway network type can set by editing /etc/NetworkManager/system-connections/your_connection
file. An example:
sudo nano /etc/NetworkManager/system-connections/"Sonera Oletus 1"
…. add a line under apn-line
network-type=5
…… save and quit
Ctrl o
Ctrl x
Different connection types:
network-type=0 = 3G
network-type=1 = 2G
network-type=2 = preferred 3G
network-type=3 = preferred 2G
network-type=4 = preferred 4G
network-type=5 = 4G
