    Here is my scenario..

    I have a Linksys E2500 router connected to a Westell modem from AT&T (my ISP).

    The router will just intermittently lose internet connection for a few minutes up to a half hour, the come back. This happens to wired and wireless devices.

    If I plug straight into the modem, the connection is rock solid with no drops.

    I have done the following to try to alleviate the issue:

    Moved the router to a different location away from any other electronics to rule out electronic interference or over heating.

    Changed out the ethernet cable between the router and modem.

    Upgraded the firmware on the router, even though the latest firmware was already installed, I reinstalled it.

    Factory reset the router and reconfigured it.

    Changed the local LAN to different subnets.

    Changed the DNS settings to Google DNS, my ISP DNS, etc.

    I'm at a loss, any help would be appreciated.

    EDITED TO ADD: I also had a Netgear router that did the same thing when I switched them out.

    Is the Westell "modem" actually a modem/router combo? If so, what LAN subnet is it using and what LAN subnet does the second router use?

    I think I found out the issue. I had company and they had brought several phone, ipads, etc. My internet connection is only 3 mbps. It seems maybe we were all polling DNS or requesting resources or something at the same time, because as soon as they all left, everything went back to normal. I never considered that because there was only a total of 6 wireless devices plus my PC via ethernet connected.

    Living in the country has it's drawbacks.

    But to answer your question, the modem is a straight modem and it uses 192.168.1.x/24 subnet while my router uses 192.168.0.x/24

    Pretty strange. Six wireless devices on one network could cause bad congestion, but certainly should not cause a router to disconnect. Anyhow, glad it's working for you now.
