On my Win 7 notebook it is no longer getting the IP from DHCP. I first notice this on the WiFi adaptor and then tried the wired adaptor and the same.
When I do a ipconfig/all neither adapter is showing up. It did install some windows updates and since it has not worked.
I did a system restore to before the updates and it sill does not work.
I did the following and reboot and it did not solve the problem either.
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log
Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log
What else should I try?
