So, my internet got cut off for a few days, and when it came back online, i can't log on to gmail, or cannot view messages on aol mail.  i noticed that in my network connections panel, i have 2 Ethernet ports, only using one though and it was combined with a gateway which showed the icon right under my 2 connections.  now i don't see the gateway anymore and my internet won't let me see various pages.
i really need help to see my emails, thx for your help

Try checking your modem settings or calling your ISP. They may have changed connectivity settings, in which case you'll have to reset your router with a new configuration.
