Hello, I am experiencing the same issue. I have been running the intial release of Kubuntu 6.06 from June until recently. Two days ago I decided to try another distro, was unhappy, and have come back to Kubuntu. I downloaded the most recent ISO and installed it. I now have the same symptons as Vijay.
When booted into the stock 386 kernel, my Intel 3945 works fine on my Dell Inspiron 9400 (Canadian version of the E1705). However, after upgrading to the 2.6.15.26-686 kernel, my wireless is no longer detected. I do have the linux-smp-686 (or perhaps linux-686-smp) package installed. -- Intel Pro Wireless 3945 is not detected with latest kernel update https://launchpad.net/bugs/52302 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
