For a week or more I have been unable to get online to publish hubs, check my account or even read my mail.The reason is low connectivity. The computer in the office next to the one with my computer is working and so are the others where I work. My computer cannot find the server. I have unplugged and waited. Nothing. At home, I get a yellow triangle with a black exclamation mark telling me about low connectivity or that I may not be able to access the internet. At home I have a NetGear box and receive service through my landlord. At work there is a wireless network router in a lab.What can I do to get back online?I get to use a colleague's computer for a few minutes like now; but I need service. Anyone has ideas? Thanks.
