Is my airport express failing or is it my internet connection?

I have used my airport express since 2008 for running my wireless network. It has done a terrific job thus far, but lately I've been having some problems with my internet connection. Multiple times a day the internet suddenly is dropped, but I'm not sure if this is an airport express problem or a provider problem. When the connection drops the airport express' orange light comes on. Is there a way for me to check if the airport express is till functioning correclty (it is after all an older model) or if I should contact the provider about bad service? Today the problem has become particularly annoying, internet dropping often, especially when asked to perform (e.g. download, upload, streaming). Thanks for your insights!
