HP Officejet 4500 cannot connect to the wireless network

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.

Well let me tell you that some of printer does not recognize different encryptions, for example if one printer is able to connect properly with WPA-encryption so other might not able to. Well I am not able to find HP's website any specifications regarding this. Well I would like suggest that do try setting it to WEP-encryption and check that it is been working, if you already having WEP then try it on WPA. When you are doing this then better make sure that the encryption chosen in your router is been seen at your printer. If you are selecting WEP in your router and selecting WPA when connecting with printer, then it very much sure it will not work.

Well I would suggest that you better go to following which is having method that how to configure your printer which will seems to support both WEP and WPA, so you would be able to get it properly and might work it out.
