Okay so Windows 10. Its great and I've been happily using it for the past six months or so. However yesterday I booted up my computer only to see a little yellow triangle with an exclamation mark in it next to my network symbol. So I went through the basic procedures of disconnecting/reconnecting, power cycling my router, disabling/reenabling the network card, etc. None of this worked so I went a bit deeper and flushed the dns. This didn't work so I rang Microsoft. After an hour on the phone with them they basically said they couldn't help me unless I paid for a higher tier level of support (!) and so I reset my router fully (which resulted in a whole lot of other issues but I managed to resolve those) and now I'm back at square one, still stuck.

When I try and "troubleshoot problems" it comes back saying "Your DNS server might be unavailable". I've tried manually setting the DNS to 8.8.8.8 and 8.8.4.4 but to no avail.

So does anyone have any ideas?
Here's the results of ipconfig /all:

What anti virus software do you use? Have you recently changed AV providers? Is the windows firewall active?

 

[zahnib]

I just use Windows Defender. As far as I know there hasn't been anything downloaded recently (i.e. no new applications). Windows firewall is on, I've tried turing it off but if there is a more in-depth fix involving Windows firewall I can try that out

Hi, go to search and type:- cmd, right click on the returned command prompt and select "run as administrator" at the prompt type:-

winsock reset (press enter) Restart computer, when finished.

 

[zahnib]

I'll give it a try

 

[zahnib]

Yep had no effect

 

[jenae]

Hi, open a cmd as admin and at the prompt copy paste:-

netsh interface ip delete arpcache (press enter) you have no connection - specific DNS suffix.

Next still at the command prompt copy paste:-

ipconfig /flushdns (press enter)

Restart your computer, then run another ipconfig/all > 0 & notepad 0 post the notepad results here. Check internet, let us know how you get on.

Still no luck, not sure what you mean by specific DNS suffix. Here are the results below

You appear to be connected to the router . . let's look deeper.

Hold the Windows key and press R, then type CMD to open a command prompt:

Type or Copy and Paste the following" and press enter


echo > 0 & PING 172.31.0.254 >> 0 & PING 216.58.199.174 >> 0 & PING google.com >> 0 & tracert google.com >> 0 & echo [/php] >> 0 & notepad 0


That can take a few minutes to complete, come back and past the result in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Thanks for the reply Old Rich, I've tried what you said and here's the result

ECHO is on.

I've had a bit of a development. I can connect to the internet if share my MacBook's connection over wi-fi, this works like a charm but of course is not addressing the problem of why the computer can't itself access the network

 

[jenae]

Hi, open a cmd prompt as admin and copy paste:-

netsh wlan show profiles > 0 & notepad 0 (press enter) please post the notepad outcome here.

I don't think it's your computer if you can connect to the internet via a shared internet connection from your MAC. Are you able to connect an ethernet cable to your computer to see if it gets out to the internet?

 

[zahnib]

Yep, originally it was connected via ethernet but when the connection stopped working I installed a wi-fi card. It wouldn't connect through this either. Then I tried sharing my laptops connection and it worked.
So currently the desktop cannot connect through wi-fi or ethernet when going directly to the router. It'll only work going router>laptop>desktop

 

[Old Rich]

Please post an ipconfig report when connected to laptop
