I am experiencing a really weird problem on my Dell Inspiron. All my other laptops and desktops connected properly.
I changed my wireless router from an old D-Link 624 to a D-Link 615 802.11N. The Dell is N compatible. Now here is where the problem happens.
The Dell 1525 does not work in WPA mode. I found the connection would drop arbitarily as well. So since my D-Link 6124 with WEP worked fine before, here is what I did.
MY CONCLUSION: Dell does not support WPA although it is published that the wireless adapter supports Wireless N, The behavior is flaky as the connection drops sometimes even sitting right next to the router. So I don't think they work with Wireless N routers or WPA. They only support WEP shown from above behavior. Other manufacturer laptop devices connect with the new WPA connection with no problem Some of them were purchased 6 months prior to the 1525.
DELL: Can you post how this will be fixed because I only want a single Wireless N router, which the 1525 should be capable of doing. There are a lot of blogs posting the same problem around WPA support for 1525 and other devices.
