Default Gateway not recognized?

Question

My windows computer doesn't recognize and/or obtain the default gateway and thus my internet on that computer doesn't work. This is the first time that it has been acting like this. I was using the computer fine yesterday and nothing was wrong with it. It is connected through an Ethernet cable. I know it is not my hardware because I can access the Internet through my Linux distro. All of the other computers in the house work, but they are functioning through wireless connection. Any ideas as to why this occurs? If I open the connection settings, when I click close, it freezes, just that window, all the time. Don't know if that is relevant. I did ipconfig /release and renew and none have yet to help me. If you need any other info, just ask. I am using a laptop that is connected to my network to type this.

Answer 1

I presume you have a modem connected to a router which has wireless and wired ability.

It sounds like the wireless units are OK but the wired one is not.

Make sure that the wired lan port on your pc is set to obtain IP address and DNS automatically. Right click on the lan connection, select properties, highlight Internet Connection (TCP/IP) and click properties button. Check to make sure the settings are ok. They may be incorrect. Then close out of this.

When you go to command prompt and type in ipconfig do you receive an IP address, subnet mask, and default gateway addresss? You should see the default gateway is the router LAN IP address (usually 192.168.x.1 where x = 0 or 1).

Check this out and this should address the matter.

Answer 2

ALl are good answers but everyone missed the bad ethernet port problem. switch the cable to a port that you know is working corretly. these ports do have problems sometime. It may also be your nic in the computer. You did not say if the ip address was a correct address that the computer was recieving. If it is a correct addres then none of this will correct your problem. If it is a correct address then you are recieving some information from your router including DHCP information just not the gateway. If that is the case. Check a computer that is working and manually set the IP information with the gateway.

Answer 3

make sure that your default gateway's ip is within range of subnet mask of your client ip configuration.
try to ping your default gateway.
if you ping the default gateway succesfully then try connect to the internet with ip addresses (e.g: http://69.147.114.210/ for Yahoo!). if you succeded then, you get the problem with DNS server.
if another computer that using same gateway doesn't have any problem, it is sure that your client computer is trouble.
check the cable or ethernet card whic connect the switch and you troubled client. are they operational? indicated by blinking LED.
do you using DHCP?
maybe there isn't any empty slot for your computer, so that you can NOT gain any ip address. try specify ip manually. if it say there is ip conflict... there yours problem. find who caused this problem. I have strong feeling your wireless connection take up all ip. or maybe someone in your wireless area try to get connection within your network. I think you can block the other wireless device within your wireless acces point. Block their MAC address, or only allow your computers MAC address. The second option is more admissible though.
If there still problem... you should provide us more information about your network topology

Answer 4

Is this PC's ip static or obtain via a DHCP server? Can you ping the default gateway? If DHCP is the IP address 169.xxx.xxx.xxx? You have a linux box, why use the Windows PC?

Test to router port by pluging your linux into the port your PC is attached to.
