That's what would be interesting here, since the time between the connection request (21:39:40) and the "network timeout" (21:39:41) is only one second, which is pretty odd. Lets see what MM is doing once it gets the Simple Connect request. </blockquote><div> </div><div>Hmm, when trying to do that, it then worked to connect... :/ Anyway, I then get this using mmcli: Bands | supported: 'cdma-bc15-aws, dcs, egsm, pcs, u2100, u900, eutran-i, eutran-iii, eutran-vii, eutran-viii, eutran-xx' | current: 'cdma-bc15-aws, dcs, egsm, pcs, u2100, u900, eutran-i, eutran-iii, eutran-vii, eutran-viii, eutran-xx' </div><div>Isn't that just listing all enabled bands, not what is currently in use? </div></div></div></div>
