DI-614+ router: Does priority go to the wired ports before the wireless?

[Rkonster]

I have my T40 on wireless, and when I do heavy downloading/uploading on one of the wired machines, the internet becomes so slow it is unusable, while on the other wired machines, it is kind of slow, but usable. I was just curious wether the router gives priority to the wired ports, because I cannot think of any other reason for this to be happening. Thanks.

I have a DI-614+ and I haven't noticed what you describe.

Keep in mind that this sort of behavior will be VERY dependent on what kind of traffic you're uploading/downloading. For instance, if one connection is downloading something using NNTP (usenet newsgroups) and another is downloading something from the web, the web connection will get hammered.

This is a result of the different protocols being used. The web uses TCP as its transport protocol, and TCP has a feature known as "flow control" that backs off when it sees a busy communication channel. In this respect, TCP is a "good citizen" of the internet because it shares bandwidth nicely with busy connections.

NNTP, on the other hand, uses UDP for its transport, which has no concept of flow control: it just blasts away regardless of whether the connection is clogged or not. This usually obtains better throughput for UDP protocols until the router's buffers get full and packets start dropping. But regardless, if a UDP and TCP connection are competing with each other, the UDP will always win.

Granted, this may have nothing to do with what you're talking about, but you didn't describe the circumstances of what kind of traffic you were performing your experiments with.

Edit: BTW, I apologize if you already knew everything I just said. I get carried away explaining things sometimes when they need no explanation. 🙂

Thanks for the reply! The program I am specifically using is Bitorrent.

Wireless also has alot of other features that may slow it down. (WEP, Connectivity, Packet loss, CRC errors and the constant request of other WLAN popping request through air)

The Roughter can snap more data coming from the modem across a hardwired 10/100 line with set specs then a floating 11/56 wireless.
