Hello, Whether I am an IT professional is debatable, however I have an interesting problem that nobody can explain to me.... I have both wired and wireless network cards on my W7 64Bit laptop. When I connect to my router via the wired network everything Internet is fine, no issues no errors. When I connect with my wireless card, W7 reports connection ok with internet access, however DNS does not work. I can ping any IP address on the net and for example browse google by using IP address instead of name. Both network cards are set to DHCP and all settings appear to be the same. I have unistalled (in device manager) the wireless card and deleted the driver. loaded latest broadcom driver for my machine, reinstalled, but still same error. Even disabled firewall in desparation. In the Event log I get the following, which i have seen posted on other questions, but none of the symptoms seem same as mine. Name resolution for the name isatap.SE572 timed out after none of the configured DNS servers responded. SE572 is my Siemens Router. Any help or pointers greatly appreciated Thanks Andy Just to add, another laptop works fine on the same wireless network along with skype on the W7 problem one.

Hi, According to your description, I suggest to perform these tests to troubleshoot this issue: 1. Run the following commands to see if it works: ipconfig /renew 2. Register DNS via command: ipconfig /flushdns ipconfig /registerdns 3. Manually configure the TCP/IP settings, navigate a static DNS IP address which is the IP address of the router. 4. Check the hosts file. Also you can add a DNS on host file 5. If the router has a firewall, disable it. If the issue persists, please run ipconfig /all and check if it connects to any DNS server. Hope that helps. Regards, Leo HuangPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
