I am not getting far with my provider so thought I'd try other routes to fixing my problem.
My new Huawei 5372s and unlimited contract will not connect reliably to the internet.
The connection is made initially but after a few minutes can no longer access the web.
It seems there is a connection to internet but this gets choked or cut off.
I thought maybe the DNS may need changing so if you have something that works let me know.
