Hello friends, presently I have set password for D-Link DI-524 router so that Wi-Fi will be secure, but when I have done that then HP Officejet 4500 cannot connect to wireless network, whereas I hardly use it. When I am trying to connect and enter password then printer fails to connect to the network. So I have checked Wireless Test Report in which it was saying that fails the test of No Filtering even although IP filters and MAC filters are disabled. So how to fix this problem, is there any proper solution for this. Please help me, thank you.
