Hi, Can anyone help, my problem is that i went to the DLINK site to secure my wireless network of which i done sucessfully but now i get a message next to the dlink network icon saying: THE SETTINGS SAVED ON THIS COMPUTER DO NOT MATCH THE REQUIREMENTS OF THE NETWORK- now this may sound silly but i don't know how and where to get to the right place then if i do ,what do i do,i know i'm thick!

if your running vista then go to network and sharing center. then click manage wireless connections and delete the profile for your wireless. then scan for wireless networks like u normaly do. enter your password for your network and choice to save the profile.
i get this alot any changes you make to the wirless sercuirty, ie encpt , passwords then they dont match the saved profile and u have to delete the old profile.
if your on xp then i would think its pretty much the same way.
