WRT54g -> Switch or Hub inside?

    Hi all,

    I've got a question. I've connect a no name switch to my WRT54g in order to expand the network ports. This works fine - off cause. But the uplink-LED off this switch is always flashing, even when there are no other connected pc on this switch. So I've tried to make a network sniffing. When I put my "Sniffing PC" on the no name switch, I only can see the traffic between this pc and my WRT54g - that's how it should be, because it's a switch and not a hub.

    But then I tried the same thing, while my "Sniffing PC" was connected directly to the WRT54G. Also there is always my server connected to the WRT54G (for my homepage, Teamspeak, edonkey....). Okay, I started sniffing and I could see the whole traffic - even the traffic between my server and the WRT54G.

    Question: If the WRT54G comes with a switch inside, I only should see the traffic between the router and my "Sniffing PC", am I right? So where is the mistake?

    Thanks a lot

    That is a bit odd. Any chance the traffic you were seeing from the server was broadcast traffic?

    Well I guess I could say, that it isn't broadcast traffic. I can see the connctions which are established via edonkey and the data which is depending on this.

    The other thing is, I'm not absolutly sure but since I've notice the permanent flashing Upload-Led of the no name switch, I also notice that the http traffic is much slower then it used to be. Even when I connect myself via http to the WRT54g. Other thing are working pretty, like edonkey, internet radio, online gaming...only something with the http-thing seems wrong.

    Can this two things belong together somehow? My knowledge isn't that good, that I can see what exactly is on the network using a sniffing tool, but can it be, that somthing is blocking the http-thing by flodding it? (whatever it is a virus/trojan... or just a wrong config in another program of mine)
