    I use a PPTP type connection with my Russian LAN ISP. Setup has been done according to my ISP instructions, and all is working fine.

    But... From time to time, some strange things happen:

    - First, no website can be reached, "Server not found" messages everywhere. Seems a DNS problem as the websites addresses that are cached (Outpost firewall, DNS cache enabled) can be reached.

    - Then, one or 2 minutes later, the internet connection is dropped (but the LAN connection remains).

    - Then, again one or 2 minutes later, the internet connection comes back and all is working.

    This happens more often when eMule is working, but not only!

    Any help will be appreciated

    Thank you!

    This could be any number of things. Have you tested the connection by some other means? If the wrt is the problem then this problem can be looked at from that point of view, however if its your isp, no matter what ideas we come up with here the connection is not going to change.

    Well, it is about 4 hours that I am checking all, stopping programs that are running online, etc.

    I had the same problem with a D-Link before, thought that using Linksys would fix the problem.

    The point is that if I do not use any router, the internet connection never drops, so how can it come from my ISP? Of course my ISP says it is coming from the router,....

    Don't know what to do :((

    It should be worth noting that Firmware v4.30.9 is the latest for your router.

    if you are using P2P, make sure your conntrack setting is set at 4096 for the table size and 600 for the tracking time.
    This should help.
    After that, if you have a dynamic IP, connection *WILL* go down for a few minutes every day or so to change/renew the IP.

    Yes those changes were done already. The fact is that even without P2P, I lose connection every.... Hard to say! Now for example I am connected since about 2 hours (that means that 2 hours ago inet disconnected!)... with emule running! Yesterday evening, internet was disconnected every 10/15 minutes...without emule running :(
