Checking an Internet Connection

[anonprivate]

The other night I could not access the Internet.

According to my wi-fi icon I was connected to my ISP. But why my ISP connected to the Internet?

Is there a method that I can use to check if my ISP is connected to the Internet, or if there is a fault at the ISP preventing connection?

Thanks

Try Ethernet cable?

The lights on your cable modem will tell you if the connection between it and your ISP is down. The lights on your wifi modem will tell you if you are getting a good connection to your cable modem.

as always, start with the hardware, including the cables and connectors. Cables can knot up, changing their electrical properties. Connectors can corrode or dirt work its way between contact points with micrivibrations, etc...
