Running XP with wired connection to router which is shared with another PC (Win7) - also wired. All was going well until I bought and installed Bitdefender 2014 rather than rely on free av. PC running Win7 is fine and can access all web/email. XP machine shows I'm connected in Control Panel>Network connections but can't get online at all. Tried restoring to a time when the PC was connecting OK but PC states not able to restore to that point. Tried two others with same result. Tried accessing with Firefox which I normally use and IE - neither work. Also tried getting my emails with Outlook but still no luck. I'm guessing that I'm doing something really basically wrong but I'm not that IT savvy. Any assistance really would be appreciated. Thank you.
