long delay before i can connect to NAS (wireless)

[reckit]

Hi There

Just bought a D7000 to replace a BT HH5 and I'm having issues connecting to my QNAP NAS using wireless. It can take up to 5 mins after connecting to the wifi before I can navigate to the NAS homepage or connect to the server. 

The unit is recognised as a connected device in netgear genie and can be connected to instantly with a physical connection. After around 5 minutes it can also connect via wifi but before that I get site cannot be reached or server not found. I never had this issue with previous router

Any help would be appreciated

Have you given the QNAP a set IP address ?

Also are you running the server on a schedule or do you have it on constantly ?
