Only one internet connection possible?

Only one computer out of two can be connected to the internet at any time. This depends on which computer started first. Both computer can ping to default gateway and googles ip address. But only one computer can ping google.com. Both computer uses the same dns address which is same as default gateway. So to conclude, one computer can ping ip address of google or any other website but it cannot display website in internet explorer. Any help would be appreciated. Thanks.

If you can ping a public IP, then traffic is going out to the internet, it sounds like it's not all coming back through the local LAN correctly.

I would recommend checking the interface's configuration (ipconfig /all or ifconfig depending on your OS, netstat to check the route, etc...) to ensure it's routing back correctly to the device, or using a packet sniffer on both devices to see if you can make a request from the non-functioning device, and see traffic returning to either system.

If you're getting a ping response then the protocol PING is using is allowed (ICMP), but another protocol like TCP may not be, or may be unintentionally filtered/blocked.
