I had the same issue on Ubuntu 10.10 and Mint 10, with PAE/non-PAE kernels, both WUBI/clean installs. The download speed was ~20 times slower than on Windows/previous releases of Ubuntu.
I solved the problem following Eric's suggestion above, by installing the Windows driver (see the mediafire link) - I didn't even bother to blacklist the corresponding kernel module. After reboot, the download speed increased to normal values. So the issue should be somewhere in the drivers/kernel module. I wanted to clear this out, since I've seen the problem reported on many forums, and the solutions suggested there were strange-to-ridiculous, involving a lot of router related config, disabling DHCP, disabling IPV6, blaming WUBI install, etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/621265 Title: Slow Wireless Connection in Intel 3945abg -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
