I am no expert but I had the same problem with my new Inspiron 1525n which arrived two days ago.

After trying several different versions of Linux I ended up using PCLinuxOS 2007 and everything including the wireless link works fine.

Might be worth downloading PCLinuxOS and running it up live?   There is fuller information in a thread I started today.

I am using Fedora 9 for my Inspiron 6400/E1505 laptop. Its wireless is working fine without my intervention.

You have a connection. Check to see what your firewall settings are or turn off the firewall temporary to see if you can get anything then.

I have an Inspiron 1725 with Dell Wireless 1505 Wireless Draft 802.11n wireless adapter and am unable to get my wireless to work.  I'm using Ubuntu 8.04.  I have tried installing the windows driver to no avail.  Any suggestions?

Thanks

I finally got mine to work with the latest Mint Linux using WEP encryption with a hexadecimal password.   The wireless indicator light on the computer doesn't come on and that fooled me at first.

Using WPA encrption or WEP with an ASCII password the password becomes corrupted and the connection does not work.

I tried several different configurations of the router then set the laptop to be compatible until I found one that worked.   Wasn't easy, have been playing about with it for a couple of days.
