I have a windows 2008 r2 domain controller. It is also a dhcp server. My wired clients work fine. My wireless clients are having issues logging into the domain. At random times, the wireless clients can not ping the domain controller but can ping the firewall. Any suggestions would be helpful.

Hi Gerald, Does this issue exist on all wireless clients or just some of them? What operation system is running on the affected computer? How did you configure your wireless network?
