Hi,

So... Is this wireless from a device in your Home ?

Or do you have a service that is Wireless by line of Sight or other method similar to a phone network to connect to your ISP ?

My Modem/router tells me when it is connected to the ISP

If this link went down the System Preferences > Network > Advanced Button > TCP/IP tab would still list the IP I get from the device.

i.e. there are other ways to check the info Network Diagnostics is telling you including the router or modem itself.

Don't forget to check the simple things first. Start at the wall where your cable/DSL/Fiber enters your house. Unplug and replug that cable from the wall, then do the same at the cable end at your modem. Then do the same at both ends of the ethernet cable between your modem and router. Also check that the cables are not damaged and that any cables are not damaged or laying near motors, speakers, or other sources of electromagnetic interference.

Then look on the outside of your house for any exposed cable splitters or phone interfaces. If you have access to these and fee comfortable doing so, unplug the cables, clean any corrosion, and reseat the cables.

Once you have done these simple things then try things for a while and see if it has solved the issue.

If it persists, it could be nearly anything between you and your ISP including their wiring, their equipment, or even your wireless router. You could connect your Mac directly to your ISP's modem/router via Ethernet for a while (bypassing your wireless router). If the connection is stable and never drops out, then it is either a problem with your wireless router or interference from many other WiFi devices that is the problem.
