Dns_finished_no_internet

[HCFC_CLARK]

Please can someone help me as I'm going insane!! I accidentally turned off my router at the plug today and since then I have been getting the error message DNS_PROBE_FINISHED_NO_INTERNET on chrome and all other devices won't connect to the internet. I have tried changing the DNS and IP settings in IPv4 which has had no effect. I've done numerous commands on command prompt, reset the router numerous times and I'm now at the point where I feel I have tried everything.

If anyone has any suggestions whatsoever please fire away. I have a dissertation due in 7 days and need the internet now more than ever!

Sounds like you may have tried this but if not try the following:

1. At the start menu open 'Command Prompt' and right click on it and run it as Administrator.

2. Type the following command: netsh winsock reset

3. Then enter and it should tell you to restart computer.

4. Once restarted try to use the browser and see if it resolves the problem.

(not sure why all devices would have the issue though so maybe also consider speaking to your ISP if they provided the router as they may be able to help as well)

Thankyou for the reply Paul, however yes I have tried this with no success. My router was purchased by myself too.

some things to try.....

Open up the command prompt and enter the command "ipconfig /all" (without the quotes). In the possibly long output you'll get back scroll back looking for the entry for your network card (or wfif card, whichever one you're using to connect to the router). Check that you have a valid IP address, probably in the range 192.168.x.x. If your IP address is in the range 169.254.x.x then you don't have a valid IP address. This will probably because the DHCP server config in your router has been wiped when you powered down. You'll need to go through the router setup again and configure DHCP properly.

Also try pinging your localhst and the router. To do that open up a command prompt and enter the command "ping 127.0.0.1" (without the quotes). That pings your local TCP/IP stack (the loalhost). You should get back four replies with round-trip times in them. If you get four Request timed out messages the problem is with the TCP/IP stack on your PC (we can probably sort that though). If that works ok now ping your router, so in the command prompt enter the command "ping 192.168.1.1" (without the quotes). If your router IP address is not 192.168.1.1 then substitute whatever address you have setup for it. If you get four replies with round-trip times in the problem is with the Internet connection from your router to the ISP or with the config in your router. If you get four Request timed out messages the problem is the connection between your PC and your router.

I hope that helps, see how that goes and come back.

ubuysa, thanks for the reply. I have done what you said and this is how command prompt looks:

Ok, that's good. You have good connectivity to your router. Now try pinging IP address 64.4.141.247 (so enter "ping 64.4.141.247). If that works (ie. you get timed replies) try pinging www.uuplus.com (so enter "ping www.uuplus.com"). They are both the same server but if the latter one fails (Request timed out) it's a DNS config problem.

I'm a tad concerned about your DNS setting in the ipconfig/all output. It appears to be 174.128.242.184 and I can't ping that address (I get Request timed out) so I'm wondering whether that's your problem. You should either be using the DNS server from your ISP or a public DNS server, so open up device manager, expand the Network Adapter section and right-click on the entry for your wifi card. Selct Properties, scroll down the list you'll see and click on the IPv4 entry and click the Properties button. Ensure that the radio buttons for obtain an IP address automatically AND obtain a DNS server automatically are both selected.

Folllowed your instructions and this is what came up:

Really appreciate the help!

And that's what all the tests show too. From these ping tests your PC seems to be fine and the router is responding normally as well, it appears almost as though your router is not plugged into the phone line....

Make sure the router firewall is not blocking access. Make sure also that the router is not blocking your MAC address (which looks like 64-70-82-50-2D-6C from the image you posted). Check also that the Internet connection settings in the router conform to those required by your ISP (this may well be the problem).

Make sure the router is properly plugged in to the phone line and make sure you don't have a low pass filter between your router and the phone line.

Give your ISP's help desk a call and see whether they can help you locate the problem.

ubuysa, just sorted everything and want to thankyou for all your help. It was, as you suggested, some settings that didn't match up on my router and ISP. +rep

Very glad it's sorted!

Hopefully the step-by-step ping testing you did will help others diagnose their own networking problems. Thanks for the rep.
