Vista has issues like that and it's documented -> http://support.microsoft.com/kb/928233 among a dozen other articles. But with just the router and what you told, any guess is just a guess.
Hello - I am looking for some help on I hope a simple problem I am having. Just rehooked up my Netgear WGR614v6 router after in was in storage for 6 months during my move. I have a Dell Latitude and I can connect to the internet when hardwired no problem. My Macbook can also connect when wired and also wirelessly. The problem is I cannot connect to my router wirelessly. Please know my PC does work in other hotspots no problem. Any help is greatly appreciated. Thank you.
