I am hoping someone might have an idea on this as I am stumped. When clients connect wirelessly to the WRVS4400N they successfully get a DHCP address from the Windows 2008 server. After they have the address they can no longer access the server. It cannot be pinged, no drives can be mapped and internet access fails because the same server is running DNS. The WRVS4400N is setup for DCHP relay to the server. Wired clients do not have this problem. Wireless clients that connect to a secondary WAP on the same LAN also do not experience this problem. I have updated the router to the latest firmware version, reset it to factory defaults and reconfigured from scratch. Turning the server firewall off has not made any difference either. I have been able to bypass the internet problem by adding a second external DNS server in the DHCP scope options. Any help would be appreciated.
