Hello Ray,

As suggested by a number of readers, I have gone back to basics and
tried the "simple" approach. I connected the Dlink 4G router direct to
an ethernet port on one of my machines, I simply disconnected the exist
cat5 connector too my hub/switch and connected the Dlink. I tested the
port prior to doing this and it worked OK and I still cannot get it (the
Dlink) to work. ON switching on the device the Docs say the led that
indicates a correct working Lan connction should come on steady and it
does not, its flashing. If its cat5 cable is disconnected this led goes
out and on reconnection comes back flashing. Three different cables were
tried all behaved the same.
Its unlikley that the DLink is faulty (allthough it cannot be completely
ruled out), so for a "Simple" install there still must be some kind of
custom config required.

>From the foregoing, I would suspect the Dlink 4G router. I would get
the supplier to demonstrate that it is working, going in to a Telstra
shop or whomever the supplier is. That will establish a basic working
state from which to get it working the way you want. As to ethernet
cables, try a known straight through, and crossover cable. Both exist,
and they are different. Most modern equipment is supposed to autosene
and configure itself, but that too is a failure point.

I have tried both straight and crossover cables and yes the Dlink is
supposed to detect wha tthe cable is.

What actually is required for a simple direct on PC install, it appears
standard eth0 setup does not work. Unfortunately when I restored the sim
to my dongle and atarted windows I could NOT get an internet connection.
After transfering the sim I tried my spare dongle this behaved the same
way but worked correctly after it was "rebooted", what ever that does.
Note: powering everything down did no good. I may get a router that will
take dongles directly and see if a can get any more success.

The USB dongles are yet another can of worms, one that I do not wish
to chase down a rabbit hole.

Yes USB dongles can be a problem, but one can usually come up with some kind
of solution. A problem I have found with mobile broadband is I have found is that
some providers DO NOT like sims being swapped between devices, with a 4G USB dongle
router, I can safely swap the dongle between a USB port on WIndows and the router
on Linux and not have the service locked out.

I may say this is P.....g me off no end currently particularly this
comming directly after my main machines mother board failed.
Note: I spent 30 years as a complex systems technician and such problems
do not usually bother me but this is getting ....................... And
not having a decent working internet connection is NOT helping AT ALL
(as I cannot easily search for help).

I have been having trouble getting photos off SD cards, I had a device
to plug them into, then a USB port. That died, and the replacement I
bought appeared to not work. Now it looks like the otherwise working
powered 7 port USB hub is flaky. I now have two ways to read the
cards, and a couple that do not work. Why? i would like to know, but
do not expect any answers.

Yes it can be a pain. I have 2 SD card readers, one is an external reader, the other
occupies a 5 inch drive bay, I have never had any problems with either. A significant
issue here is that USB while simple to use is VERY complex under the hood and the
more complex something is the more problems one has in the end.
