OK I have done this:

- Checked my modem, there is no option "transparent" option. Anyway this modem cannot act as router.
- I have changed in modem the IP address of the configuration interface (web interface). The IP was the same as the DGL 4500 (192.168.0.1). Not sure if it's a problem on the WAN interface.
- Reseted my DGL 4500 (back reset button)
- I have configured my PPPOE connection in the DGL 4500
- I have configured one route for torrent (192.168.0.10 port 1723)
- Cable from Modem to router is Cat6
- Cable from Router to PC (192.168.0.10) is Cat6
- Started to use my connection with a torrent in background.

I will post the result soon...

Yes, I have seen this on the DSL side of the MODEM giving a private 192.168 ip address, this is not really idea since routers can also have this address for the LAN side of the router and could cause conflicts. I would ensure that either device is not using the same private IP address. Ideally, the ISP Modem should give a 2 character Public IP address, i.e. ##.###.###.### to the WAN side of the router. Then the router can be set up to the Private IP address of 192.168. IMO, the LAN side of the router could be anything you really wanted. Some people use a private IP address starting with 10.###.###.###.###. I've set mine to 6 on the LAN side.

Let us know who this goes.

In regards to the OP, can you supply me with the complete log during one of these events? Should be mostly Info priority, but make sure you go through it and remove any personal info. (Public IP's, MAC's, etc). I think the answer will lie there.

It sounds like the heavy UDP traffic is lagging all other traffic. Question is why. Here are just a few things to try. I will have more idea once you give us some log data.

Basic > Internet > Manually configure > Uncheck Unicasting.

Advanced > Advanced Network > Check off "Enable Multicast Streams"

Advanced > Gamefuel > Disable Gamefuel. (For testing purposes)

PS. Great article here. http://www.isoc.org/INET97/proceedings/F3/F3_1.HTM

PPS. D-link, want me to find you a better HTML tagging system?

OK my setup does not work (poor speed and disconnections). I have tried tips that Furry send me by mail but same result.

I can't access to the log because when the router crashes the interface 192.168.0.1 is not available. I need to reboot the router and this clear the log...

So i use my old router (works great) and I cry for the 150$ I lost. Not sure I will buy some D-link stuff in the future.

Anyway thank for the help guys.

I would go ahead and call DLink and talk to them. I have a feeling this is a HW issue with the 4500 as a different router works an the Config file you send me works on my 4500. I think we've narrowed the issue as best as we can. Time to get DLink on the line. Let us know how it goes.

Hard reset the router (hold reset button during power up for prolonged period). Factory settings will be applied.
Then re-apply the 1.22NA firmware download and MANUALLY configure the router settings.  As a start, simply set your admin and wifi password and ssid.  Leave everything else alone.

Do not ever try to load previous configurations after you flash, especially if you had trouble before.  (I know it's a pain.)  Immediately after this "virgin" config is completed, save out your settings to a file with the firmware revision as part of the name (so you don't mistakenly pick it for a different firmware rev.).

Post back with your results, please. Good luck.
