Thread: The DNS server is not responding

OK.. makes sense... I think


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?

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).

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.

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/d...heet-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


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

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.

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
