[ubuntu] XP internet access problem with dual boot setup

view story

http://ubuntuforums.org – Hi All from a Ubuntu noob, I recently resurrected a Dell Dimension 5000 desktop so that I could dual boot Windows XP and Ubuntu. The system has two 2 seperate SATA hard drives, 1 x300Gb for XP Pro(SP3) and 1 x 80 Gb for Ubuntu 12.04 LTS. I installed the XP first on hda (300Gb) with the 80Gb drive disconnected. Then fully updated that installation and added a few goodies. This installation worked fine along with Internet access through IE and Firefox. The installation was used for week or so before the next stage. I then swapped the XP installed disk to hdb and connected the 80Gb disk to hd (Hardware)
