THIS laptop I am currently using is of course able to connect and surf the internet. However my main PC, which is a Windows XP (SP3) 'gaming rig' is connected (same speed as this one...about 56 mbps) but all pages give the 'Unable to load...' error and tells me I should check my internet connections.
This all started after my roommate tried to install a brand new router (Linksys WRT 1200 AC Dual Band Gigabit) with which we all were unable to connect to the internet at all. So I unplugged the new router and re-plugged in the old Linksys Wireless-G 2.4 ghz router. Now I am able to connect only with this laptop and no one else seems able to connect without great difficulty.
This laptop is running Windows 8 (updated) for what that is worth.
My XP rig though has the aforementioned problems and running the troubleshooters and 'Repair connection' things do nothing.
I apologize if I have failed to post some necessary details and I thank you in advance for any help.
EDIT: Forgot to say that my browser is the latest Firefox (51.01).
