Can't connect with dongle

Asked by bamber

I have a T-Mobile 1750 dongle.I have added a rule as per forums for this dongle. Made no different with or without. Mostly it works without problems.However, sometimes, I get a dialog box in which a password is requested. If I enter the password in the Connection Details or sudo password that fails. This line appears in the system logs:
get_secret.flags: 'assertion is_secret_prop(setting,secret_name error) failed'
 Sometimes deleting the connection and starting with a new connection works. Sometimes removing the dongle and replacing works. Sometimes nothing works but then it starts working again. This is a recurrent problem from 2009 onwards.

Thank you. I have installed modeswitch. I shall download the suggested link and study it later.So the following migh duplicate that advice
After some digging around I found the following might be a solution.However, I have not tried it out because I have to wait for the problem to recur.
sudo rfkill list all # checking if blocked
sudo rfkill list all # unblock
sudo service network-manager restart # some report this works even if not blocked

Can you help with this problem?
