Hey all,

So last night I got back from a week long trip and one of the first things I did when I got home was turn my computer and the modem back on and I noticed that my computer was saying it was connected to the network but not to the internet. I then tried connecting my android phone to the modems WiFi and I had the same problem, the phone would say its connected but I wasn't able to open any webpages. I then tried the network troubleshooting in Windows 7 and I got the message "dns server isn't responding".

I've tried disconnecting/reconnecting the computer, and unplugging the modem for a minute but neither of these helped. Then this morning my dad rung our isp, slingshot who couldn't find the problem from there either. The guy said that the dsl light on the modem should be constantly on, but it only flashes. he then went on to say that they can send out a technician to find the problem but if the fault isnt with the actual phone line then we'd be charged up to $200....

I've done a bit of googling and the "dns server isn't responding" error seems to be quite common, one of the only straight forward answers I could find though was to unplug the modem for 10 seconds which hasn't helped.

Any help would be greatly appreciated.

dont ping what freitasm asks for, its not a valid address ;)

can you open a command window and do an "ipconfig /all" command and paste the results here?

and try ping one of the callplus/slingshot nameservers on 202.180.64.2

Also, tell us what make/model of adsl modem you have.

Sorry can you please explain what I am supposed to do with that number? I don't know much at all about networking.

I've tried typeing 'ping 2092.175.128.164' into command prompt and the message:
"Ping request could not find host 2092.175.128.164. Please check the name and try again."

Was this what I was supposed to do?

that was what you were supposed to do, but the IP address freitasm gave was incorrect which is why you got the error.

try "ping 202.180.64.2" instead

First it should be "ipconfig /all" without the space between / and all. That's why you got the help page.

Second, that ping means there's a configuration problem in your router, since it's not even going out to the Internet. Have you changed LAN configuration, IP addresses, etc in that router lately? Or someone else did without you knowing?

so your router is probably found at http://192.168.1.2 - do you get a login page when you click this link in a browser?

if you can get that far, login with user: "admin" password: "password" and see if you can get to the status page shown here: http://flyingmac.com/presence/help/configureRouter.html?url=%2Fenglish%2Frouters%2Fport_forwarding%2...

this should tell us a little bit about the router and whether it is connected or not

Actually good point... The router *IS* connected to the wall plug, right?

I've setup the modem again and here's the results:

lol, thats not quite what i meant - but i suppose its worth asking :P

i was meaning more that we could see if we have a DSL (line) connection but no PPP (authentication) connection etc.

The PC connects to the router fine it seems. After all is getting an IP address. The router is not connecting to the Internet though.

RealityClash: I've setup the modem again and here's the results:

Are you sure you selected the correct options during the setup? Is the modem syncing? Can you post the stats please?

if you go to the status screen in the router config, check the connection status and ppp connection time. also check the "system log" page from there and see if there are any authentication errors showing in the log

also, have you had any new neighbours move in while you've been away on your trip? maybe your line got reassigned accidentally somewhere along the way..
