Hi all, I just convinced my wife to switch to Linux/GNU from Vista after her laptop was extremely slow and infected with spyware. I use Ubuntu 9.04 in my desktop, but I tried Linux Mint sometime ago, and I thought it can be used as an easy transition from windows, also since it is based in Ubuntu I can help her to migrate.
The installation was very fast, and at the end everything was working, she was happy. The only thing we noticed was that the Internet was slow. Slower even than her old Vista. We have been using the 1.5Mb Cox service and we felt it was slow but we could manage. So since I wanted her to keep using Linux Mint, I called Cox and upgraded our Internet to the 13Mb.
Now, my question. My desktop (that uses a PCI wireless card) reports a download speed of about 8.5Mb (according to a Cox technician is not that bad, since I'm behind a router) but my wife's laptop is getting 1.65Mb

Here's my wifes wireless card info using ifconfig

wlan0     Link encap:Ethernet HWaddr 00:16:44:b9:27:ae
          inet addr:192.168.1.134 Bcast:192.168.1.255 Mask:255.255.255.0

If it is any help, I'm using a Linksys WRT54Gv8 / GSv7 with a DD-WRT v24 RC-5 firmware.

After wondering on the forums I think my problem is with IPv6. Has anybody had a problem with IPv6? How can I disable IPv6 on Jaunty (Mint 7 is based on Jaunty0? Ive checked some tips from the forums (upgrading the kernel, using option ipv6.disable=1 see: http://www.ubuntu-inside.me/2009/04/howto-disable-ipv6-at-ubuntu-jaunty.html) but nothing.

Any help with this problem will be greatly appreciated.

Thanks
