The DNS server is not responding

[Pedro_The_Swift]

is there supposed to be something in here?

[Mick_Marsh]

Not if it's auto detect.

Having interweb problems? so am I.

Must be Christmas.

[Tins]

Hmm. Depends on you ISP. Mine autodetects when I am not using my various VPNs, but it populates that field:

ISP is iinet.

We had the same issue , DNS with the connection crashing out sometime around midnight on Xmas eve. We were told that it was a Telstra problem based in the chermside exchange. It took us all day to get back on line as the telephone tech staff couldn't get us sorted until resetting all our passwords . But they couldn't tell us exactly why it crashed out.
Felt isolated without being able to connect at will. To make matters further complicated for some reason I couldn't get my phone to send texts but with the settings the same , as far as we could tell , the second identical phone would. A task I will look into at a later date.

The DNS server within Windows, should be the IP address of the router(that connects to the ISP).

As I remember your network config, your PC connects to an access point(or switch) and the AP connects to the main router wirelessly.
Do you have a separate modem, or is it a router modem too(can make a difference).

So on the main router(to the ISP), or modem) this device should be set to do DHCP.

Don't allow the access point to do DHCP as it confuses the network settings that Windows wants to connect too(unless you want sub networks within your home network).

So be sure the AP doesn't do DHCP.
Windows TCP/IP settings(check both IPv4 and IPv6(if you have IPv6 installed too).. and they should be set to automatic(and then the router gives the PC machine it's IP).
Shouldn't have to set DNS server info on the PC's network connections at all.

One thing tho is to manually set IP values on the router for all devices, so that when those devices, or router reboot, they all remain static.

Not a good idea to connect to a router via wireless tho, as it can mess up connections as they change and restart.
So configuring a router is usually done better when the device used is wired to the router(even if only temporarily).

If you have internet connection issues, check the router's status to see if it's lost it's IP address or DNS server values(ie. to the ISP).

Pedro,

You got things behaving themselves again? If it's a telco related DNS issue, you can always manually configure a Public DNS server in the mean time.

Easiest to remember I reckon is 8.8.8.8.... but that belongs to Google.... so as long as you don't mind Google knowing everything you do - its a quick and easy answer....

Otherwise this list may help: DNS servers in Australia (https://public-dns.info//nameserver/au)

[Pedro_The_Swift]

Thanks everyone,, no matter what I try, windows command commands, resetting apapters, playing with Ipv4/6 NOTHING seems to cure it,, Grrr.

and Mark,, I tried that sequence, windows wouldnt accept it??

[Pedro_The_Swift]

No chance of me connecting via wire to the home router Arthur,,

[Bytemrk]

Pedro, are you posting form another machine going through the same home router as the problem machine.... or are you posting via phone or some other direct route to the net? Pardon the pun [bighmmm]


If you're not , what router? and have you tried the simple stuff like restarting the router?

[trog]

Michele spent about an hour on the phone with Telstra. They talked her through. Also having the iPad helped as some information required was easy for her to access from there. Half the mucking about was due to so mis information re letter case in the codes. Hope this might help

[Pedro_The_Swift]

Pedro, are you posting form another machine going through the same home router as the problem machine....

yes, but using a wifi dongle
its only on ethernet through switch to WAP that I'm having the problem,,


, what router?

Telstra F@st 5355TLS

House Modem downstairs
TP-LINK AP300 WAP upstairs.
from WAP - via ethernet to switch
from switch via ethernet to NAS and seperaltely to PC




make any sense?[bighmmm]

[Bytemrk]

OK.. makes sense... I think [biggrin]


It sounds to me like you don't have a problem with DNS from your ISP. The router / modem connecting you to the internet is passing DNS to the device you are posting on .... (unless of course you have that set manually.)

I would suspect the issue is with the upstairs wireless point passing that DNS information on.

Can you confirm if the device you are posting from is connected wireless to 5355TLS or the AP300?.. I suspect its the Telstra Modem. You should be able to check for connected clients on each admin screen.

If it was my place - I'd simply set the Windows box up with manual addressing...maybe I'm a little old school..... but less things seem to go wrong if everything that matters is set manually.

Even at work where we use DHCP extensively over multiple subnets - I still set things like servers, printers and network gear to static addresses..... far easier to troubleshoot whats going on IMHO.


Edit: Another question for you.... The wireless point upstairs.. is that set up to extend the existing Network range ( i.e. same subnet) or supply DHCP on aa different subnet?

[Pedro_The_Swift]

can you start at the start for me Mark?

AP or client mode?

refer to previous post regarding ethernet cabling

I want to use client but---

AP (access point)

I take it this is your router for the house that is plugged into the ISP supplied router (often mistakenly called modem).

[Pedro_The_Swift]

No Mick (try and keep up[tonguewink])
the TPlink ap300 is a wireless access point upstairs. thence via cable to switch then nas and PC

So, no internet connection, then.
You don't have a Domain Name Server in the system to resolve the domain names.

[Bytemrk]

Mick....

My understanding is it looks something like this:


Upstairs:

PC / NAS-------Ethernet------Switch----Ethernet----- AP300 >>>>>> wireless to downstairs



Downstairs:

ISP-----------Telstra Router >>>>>wireless to upstairs


Is that right Pete?

If I understand what you are trying to do right, looking at this: http://static.tp-link.com/res/down/doc/Datasheet-AP300.pdf I'd be putting the AP300 in repeater/Bridge mode.

This isn't specific to the AP300 but generically covers what you are trying to do I think. TP-LINK Tutorial - Expand your wireless network - YouTube (https://www.youtube.com/watch?v=svPB8aBXI4w)


Did this set up ever work before you rebuilt the PC or have you rearranged the network somehow?

[AK83]

I dunno how TP-Link devices work, but I had a quick peek at their datasheet and config sheets.

The way Pete has the network set, using a wired connection to a switch off the accesspoint and then wired connections to the switch for NAS and PC ..
TP-Link recommend to use Client Mode for that scenario.

They recommend Bridge/Repeater mode for Wireless to wireless devices connection type, but the connection type below that mode, in the datasheet link Mark posted shows Client Mode for Pete's setup.

The important points to note:

Have you been able to log into the Access Points admin/setup/config webpage via your PC?

Once you've established that connection(PC to AP) and you're in the admin/setup area, look for the Client Mode connection type, and make sure the AP uses the same wireless type as the wireless signal type on the ISP modem(or gateway, or router .. whatever you prefer to call it).

eg., if the ISP router is set to use 2.4Ghz wireless, and the AP is set to do repeating function via 5ghz then obviously it won't connect to the Telstra router.
(that's Page 20 on the AP300 user guide)

The next important thing to check and test is:
1/. find out what the (internal) IP address for the Telstra router is. most common IP addresses will be 10.0.0.1, 192.168.0.1 or 192.168.1.1 .. or something like that.
2/. In the AP's config area is a setting called Diagnostics(Advanced->System Tools->Diagnostics)
3/. set the test type to Ping(not Traceroute!), and type in the Telstra router's IP address in the top box. The other boxes don't really matter that much, if they have values leave them, if not, make them [4], [500ms] and [64bytes] .. and hit the start button.

Hopefully you have a connection between the telstra router and the AP and the info in the box below will display 4 packets sent, 4 packets received and 0 lost.

In the DHCP area(Advanced->Network->Lan) page the default mode is set to Auto for DHCP.
This part assumes that the Telstra router is set to do DHCP(which is the default mode).
So the AP will be assigned an internal IP address automagically once it connects to the router(the ping test above).

So while you may be able to connect to the AP via the PC(and NAS box) .. it's not automatic that the AP has connected to the Telstra router! And that last part is the internet connection.

[Pedro_The_Swift]

Thanks everyone,, more to do..

and no matter what I do I cannot log into the Access point anymore,, all the lights are on, reset, switched off, ethernet or wireless it just doesnt want to join the party,,


oh and heres one,,

should a ac1200 wifi dongle have dual mac adresses for each range?

this last to sort out whats what on the house router

and---

will both show up as connected?( at the router)

I am beginning to think this access point has gone AWOL

[AK83]

...

oh and heres one,,

should a ac1200 wifi dongle have dual mac adresses for each range?

....

Most(actually all that I've dealt with) wireless devices with 2.4 and 5 gHz access use different mac addresses for each radio type.

I think on some devices, there may be some some advanced settings where you can set the device up with cloned mac address for both radios.
Can't remember which device I have/had that had this ability .. but otherwise as you see it is the norm.

Assuming that you've rebooted or reset the AP to try to get into it too?
Can't recall, but isn't the AP bought new just recently(or was that the switch)?

Could be THE problem. I prefer to assume the other way tho.

Connect it directly to the PC via as many different methods. If via wire, I'd try two more!.
Eth cables are more likely to break than a router/ap is .. just using the law of probabilities.
And while the theory says that a wifi connection to the devices admin pages should be no different than a wired connection, my experiences have been completely opposite to what the theory says.
Too hit and miss for my liking, so I always do it via wire.

eg. even on the Telstra router .. if you have a laptop you could use, access the routers config pages via the wired port of the laptop.
(I have a small Windows Tablet with an eth port just for this purpose)

[Pedro_The_Swift]

yes AP brand spankers

home router looks this way,,
AP switched on, all lights lit,
wifi dongle connected to router,, running 2.4,,

[AK83]

....
wifi dongle connected to router,, running 2.4,,

So the router doesn't have built in Wifi?
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.

[Pedro_The_Swift]

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??
[bighmmm]

[Pedro_The_Swift]

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.

[AK83]

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


....

and what is a D4-6E etc??
[bighmmm]

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:4B:DD, or 61:3A:DE: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?

[Pedro_The_Swift]

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

[AK83]

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! [biggrin]

[Pedro_The_Swift]

[bigrolf][bigrolf][bigrolf][bigrolf]

All working, :Thump::MileStone:

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.. :clap2::clap2::clap2::clap2::clap2::clap2:

[AK83]

Good to hear of your success! [thumbsupbig]


.... [It took two weeks of emails with telstra just to find out you cant change the router IP...]
....

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 :p .. 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 [bighmmm]
So my thoughts returned on how to mutilate this modem/router .. thinking .. maybe a few excessive voltages may fry it a little [biggrin]
So onto google, and found a hack to disable the routing function, and turn it into a modem only [thumbsupbig][thumbsupbig](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).

[Bytemrk]

You know you've used up all your free tech support hours don't you Pedro..[biggrin].

Glad to hear it's now behaving for you...

[incisor]

But internally, if it has routing capability, then almost certainly it'll have some way to have it's internal network address range configurable.

most telstra routers have been lobotomised and even tho you may change it it won't fully support it, so your better off either using the default address space or plugging an access point into it and letting it handle the routing for your internal network.

you need to remember also that windows really doesn't like crossing c class boundries if you wish to browse networks. there are ways around it but most aren't pretty.
