Wireless Access Points, Network

Hi, I have wired 7 access points with Cat 5 and configured each with a separate IP address. They work fine for a while, anywhere between 3 - 8 hours and then all lights on router and switch start blinking like mad and you lose all connections to the Internet. I have replaced the switch and the broadband router but still the same.

Have you checked for a firmware update on all the devices?

When the lights start "blinking like mad", remove the cables at the router one-by-one.  Wait a couple of seconds between each removal.  You want to note if the lights go back to normal after a cable is removed.  If they do, then you want to check what is on the other end of that cable and what it is doing.

Is there any chance that someone is connecting a device right before this happens?

This is typical description of network loop. Do you have redundant links in your network?
In some cases it can be caused by bad network card.
