That is, why the dongle on the router?

if it has native Wifi, dongle isn't needed.

The router has native 5G wifi .. if you can reconnect to the AP at some point(maybe after a rebot/reset), try switching to 5G connection mode(not forgetting to also set it to Client Mode).

Going by the screengrab you got there, there's an Android device at 10...01
** (I thought that 10.0.0.1 was an address always reserved for the DHCP device, but I haven't personally ever owned a device that defaults to that internal address range)

Then you have a device (wireless) at 10.0.0.15? What device is this? Could that be the IP address of the AP?
Telstra TV is obvious.

The dongle is temporary internet---
10.0.0.15,, I would ASSUME is the dongle
bit hard to test--------

that 10.0.0.1 would be the missus's tablet,,,

thats was the question about two wifi connections at the router for the two wifi ranges,,

but even if you say "yes" or no!
why do they show up different on that screen grab?

and what is a D4-6E etc??

The same 3 cables have been used all the time,
hmm (bloody formating!)anyway the switch tests 3 ways when cycled,, and has been green across the board all the time
so maybe the cables are ok,,,




this from the switch manual--
Cable Diagnostic
−
LED Indications
When the Switch is booted up (when the Switch is fi
rst powered on), the Cable Diagnostic function is
initialized and run. The Cable Diagnostic function will detect three common faults in an Ethernet cable
connecting the Switch to a remote network device: an open circuit (a lack of continuity between the pins at
each end of the Ethernet cable or
a disconnected cable), a short circ
uit (two or more conductors short-
circuited), and improper termination (a termination re
sistance greater than the sp
ecified 100 ohms). Any of
these common cable faults will be detected by the Ca
ble Diagnostic function and the LEDs will display the

results of the Cable Diagnostic function as follows:

Open, Short, or Improper Termination

−

Speed

LED: Amber

−

Link/Act

LED: Off

Cable connection good

−

Speed

LED: Green

−
Link/Act

LED: Off
The Cable Diagnostic function operates only during the Switch boot up (when the Switch is first powered on).

The Cable Diagnostic first scans the five Ethernet ports

to determine if the Ethernet cable is in good working
order. This process is indicated by the

Speed

LED blinking green for each of the five ports, sequentially. The
initial port scan takes about 10 seconds. If a cable fault is detected, it is indicated by the corresponding port’s

Speed
LED glowing amber for 5 seconds, after the initial port scan. The Switch is then reset for normal

operation. It takes about 2 seconds for the Switch to re

set. The entire Cable Diagnostic process takes about 17
seconds from the time the Switch is booted. So, from the time power is first applied to the Switch, about 17

seconds is required before the Switch will begin normal operation.
Note: There is no display of cable faults detected by

the Cable Diagnostic during the normal operation of the

Switch, only when the Switch is booted up or power-cycled.

Ah, OK! re the dongle thing(I was thinking a wifi dongle for comms to the wifi devices in the home).
Makes sense now.

D4:6E... info is the IPv4 mac address system.
it uses single digit numbers and letters(up to F), in a system of two values per separator, with 6 separated values. separator is usually marked as not -), but that's not important.
Two random examples of IPv4 mac addresses are 6F:44:3D:1A:4BD, or 61:3AE:0B:9E:00.
There's a way to convert them to IPv6, can't remember now, and there's some added padding from IPv4 to IPv6 .. or something like that.

When I set my devices up in my router, I always look for their IPv4 addresses.

IPv6(as shown in the same info box) has that mac address type you see.
Same thing, same function.
(for curiosity sake) IPv6 mac address system allows billions/trillions more devices do to it's larger value range.

So, with the knowledge that you've temporarily using a dongle for internet access now, I'd say more likely this could be the culprit.

But as before, in terms of importance, I'd be trying to connect from PC to AP admin/setup webpage, and going on from there.
Can we assume that the other devices(eg. wife's tablet) have net access?

yes the wifes tablet has access,, but its connected directly to the home router, just like my temp wifi dongle.

OK, so net access has been 'confirmed'.

Next setp is to determine connectivity from PC to NAS.
Log into the admin webpage for the NAS.

Assuming that you're PC can log into the NAS admin page, look for the Newtork Access area in Control Panel.
In the Network Access page, look for the DDNS tab on the main page of that tool.
Don't make changes you're not sure of, but in there, under the DDNS config area, there is one small bit of info that shows you your current WAN IP address.

That is the internet IP address you're router/wifi dongle has achieved from Telstra.

No idea what type of IP address range Telstra uses, but to confirm that It's correct, you can just use a net service like "My IP address" via a google search.
Any device in your home network will show the same WAN IP address. So no matter how you search for this info, it'll be the same fro your router/Wifi dongle for that moment in time(it can change tho!)

So with the above, if your NAS shows the same WAN IP address as what your router or searching has shown up, then you can be sure that the NAS will be connected to the internet.
With the NAS conencted via vire from switch to AP, then AP must have net connection to allow it to give net connection to the NAS

Simple process of elimination type stuff.

So, if cables come up good, and PC to NAS connection comes up OK ... and NAS can connect to net .. then PC to AP must be bung(more likely a PC issue).

That's my usual method for tracking down errant devices ... find the devices that do work first ... then start concocting evil ways to violently dispose of the errant stuff!

All working,

In the end I had to change all the ip addys to the same range as the router, [It took two weeks of emails with telstra just to find out you cant change the router IP...]
AND reserve those numbers. sounds simple when you say it like that..

A HUGE thankyou to Sean Mark Dave and AK..

Good to hear of your success!

....

Telstra will say that(and it may well be true) .. but I'm thinking with a small hack(on the router) it probably can be changed ... BUT!!

Note tho, you have to specify which IP address you want changed too!
You can't change the WAN(internet side of the router) IP address .. this one is definitely a Telstra setting, which the router will pickup.

But internally, if it has routing capability, then almost certainly it'll have some way to have it's internal network address range configurable.
(don't know this, as I don't have anyone that uses Telstra, so I have zero experience with their gear).
You need to know the router model number, and a quick search online(usually some of the best info will come from somewhere like Whirlpool).

When I changed my Optus(cable) connection to a new Optus cable connection, they sent me a new modem/router to replace my old one.
*side note: I changed from Optus cable to Optus cable .. because my old modem was only capable of up to 30Mbps .. on a 100Mbps capable connection .. and I wanted a new modem, and they wouldn't give me one, and I had plans to mutilate the old one .. but stopped short and I relented and updated my cable plan .. new router.

So anyhow, when I was talking to the Optus sales person, I specifically asked that they send me a Netgear modem router, and not the crappy Linksys model they also send out(bad experiences with brothers) .. and of course they sent me the Linksys modem/router
So my thoughts returned on how to mutilate this modem/router .. thinking .. maybe a few excessive voltages may fry it a little
So onto google, and found a hack to disable the routing function, and turn it into a modem only (which makes the Linksys thing less unpalatable).
Even tho the 'hack' seems a bit daunting, it's actually pretty harmless, and all it does, is that it reveals a button box on the admin page to allow the ability to set [bridge mode].
This setting is disabled with the default Optus firmware, and whilst in the browser you open the source of the html code for that main admin page and change a few bits. close the page and reopen it, and bingo! .. the setting is revealed.
It only stays 'hacked' for as long as the modem router is powered on, or not rebooted. you can turn it off at it's on off switch and it's stays hacked, but remove the power cord, or reboot it and it returns to the Optus default .. which is bad, and I then have to redo the 'hack' all over again.

Note that some hacks involve loading a totally new firmware .. which of course involves risk.
But some hacks are psuedo, and only remain active as long as the device is running.

The modem/router Telstra send you won't be unique as a device, but will run a unique Telstra firmware.
I'd dare say that they would have had it setup to not allow access to the bit setting for IP addresses or something. I doubt that any router would be built that didn't allow the ability to set IP address range(s).
