Re: DNS Problem

Hi, try to disable or reinstall your modem, then reenable it, see if you have dinamic DNS or DHCP on. or you have static ip?
check your router too.

Trying to connect two computers to the internet through a router (not wireless) having problems after connecting both computers to the router, only one computer has internet connection. My internet...

Initially check whether the ip address is assigned in the computer in which internet is not browsing using the command ipconfig/all for windows and ifconfig for linux.If ip is present try to ping the default gateway ip address,if ping is success there is no issue in the cable you used and also with ip address.If ip is not assigned assign ip by manually or by using dhcp of router.Enable and disable the lan card in the router so that sometimes the problem get resolved.After ip is assigned and ping with router is ok .Ensure dns servers are correct else give google public dns server try to ping in command prompt if ping is success then you can browse.

1231 ping error using windows vista cant connect to the internet as a result

There are some suggestions here

Try disabling ip version 6
and try an ipconfig /all to make sure all your settings are as you would expect.

Try pining the loop back adaptor
Then try pining your Default Gateway (value from ipconfig output)
Then try pining your DNS server.

Any other machines on your LAN you can ping.

This should help you narrow it down.

Hi, Go under network connection Right click on wireless Network connection or LAN connection (depens on what you're using to connect to the modem, a cable or through a wireless connection) and then properties. Scroll down until you see TCP/IP and double click on it. Make sure that it's set to obtain an address automatically and to obtain a DNS server address automatically. If you are using a router, do the same, but in this case you can set a static address. The subnet mask is and the DNS address has usually the same address of your router.

No internet connection, system stuck on ''acquiring ntwrk address''

It's doing this because it's not getting the IP from either the router or the modem. Goto Start, run and type cmd. Now type ipconfig /all. On this this list you should see IP address = 192.168.??.?? andDefault Gateway = 192.168.??.??. If your getting both of these addresses then your system if infected with virus. I suspect though that your list is probably not filled out. If so type ipconfig /flush dns. Then type ipconfig /renew. These commands should bring you back online, if not I would call Conmcast and have theme ping the modem. If the modem pings fine I would say that either your modem cable or network card are faulty.

Hi there
It could be a simple matter of bad drivers, go to the motherboard manufacturers website look for your model mobo and download the lan/network driver.
Then go to device manager and uninstall the lan, reboot the pc and reinstall the drivers you just downloaded

Good luck

Netgear: Desktop the modem and router are connected to will not allow me to get on the internet, but the laptops work.

The PC needs the right IP address from the router. In Control Panel, select Network Connections. Click on LAN connection. Select TCP/IP and click on Properties. Make sure "Obtain an IP address automatically" is selected and the address of your router ( usually) is entered as the DNS server.

Another thing you could try is to swap over the cables on the router. (the one to the modem and the one to the PC) then restart the PC.

I cannot communicate with primary dns server is there a way i can reset it automaticaly or manually

You cam try doing a power cycle. Turn off the modem, router (if you have one) and your computer. after 1 minute turn on modem first then router and computer. If you still can't communicate or ping the DNS it could be a firewall that is blocking it.

Check out your internet connection and its settings, whether it is dial up or broadband oriented.
then you have to know about your ip address of dns server in the network setting places.
