El Capitan Network Prefs reports that my internet dongle (Huawei HiLinkE3131) is not connected, see the note by Status in the following screenshot. The device is mounted on the desktop and the LED on it is lit so it has made a connection with the ISP. Network preferences are all the same as Yosemite and mavericks which are still on this mac. has anybody got any experience with this configuration or any hints or tips as to resolving this situation. Thanks.
