When I try to connect to wi-fi connection via my home wireless router (Hamlet HSNW254) the connection test always fails: ad first the icon gets green, with all the bars shown, and at the end it becomes red, saying check DNS (error 500XX or so). My wireless LAN works very well with every other device, including laptop computers and my WII. I have no security keys (WEP or WAP). I tried to configure all the parameters in my wireless router, including static and dinamic DNS, "opening" ports for my NDS, but everything failed. So, I was wondering if there was any documentation explaining the in-depth functioning of wifi connection, as it's actually impossible to make any serious debugging. For example, I thought there may be a problem regarding the kind of internet address used, but there's no way to figure out, as the error condes are useless.
