Firstly please note that the Huqwei (Broadcom) modem is working perfectly. It connects to the Internet which can be reached by any PC or mobile phone which is WiFi-enable (i.e. has an inbuilt WiFi module or a USB WiFi adaptor). My problem is that I can't wire-connect my desktop PC to the modem. The modem has three sockets on the back: one USB and two LAN. These are primarily intended for other peripheral devices. These should include my desktop computer. Wired-connections should happen automatically; these days there is no need for device names, passwords, etc. On my Ubuntu 16.04 the connection icon window shows "Automatic Ethernet". Clicking on that makes the connection. thereafter connection is automatic. Im situation that is not happening. Maybe Ubuntu 1604 does not have the driver for the modem in its library of drivers. Daniel: The above preamble is my response to you remarks. In sort, it all automatic or should be. Chris: Thank you for the ubuntu support URL. I will definitely consult through it. Terrance: Yes, clicking "Automatic Ethernet" enables a wired connection. With my previous Telstra modem I deleted all connection information such as Mobile Broadband, Ethernet and then the "Automatic Ethernet" line appeared in the connection window. No need to configure any more. Lindsay: Interesting - you have made a wired connection using the USB socket. I have tried that without success. Question: Which version of Ubuntu are you using? My Huawei modem has two antenna sockets behind a plastic cover which is swivelled out of the way. I have plugged in my external patch antenna via these sockets. Of course there is an alternative to wired-connection - WiFi. My desktop PC is not WiFi-enabled, however I have a 802.11n USB (WiFi) adaptor. I'm told that they work with Linux OSs but no luck so far with it on my PC. Thanks again, Geoffrey </body> </html>
