AT&T U-Verse – Internet – Gnutella2

After a fair amount of experimentation and “thinking”…

As I posted earlier that AT&T U-Verse Residential Gateway Router doesn’t handle a large number of connections well.

In fact, when you try to have large numbers of simultaneous connections through the router traffic can slow to a crawl.

It appears that this sluggishness might be related to large numbers of inbound connections (which further substantiates my theory that this might be by design).

With Peer-to-Peer (P2P) file sharing systems such as Gnutella 2 (found in Shareaza, MLdonkey, Morpheus, etc) operating in hub mode you’d see a far greater number of inbound network connections than with the same protocol operating in leaf mode (or most any other P2P software).

A simple work around (though not necessary a good overall solution) is to disable your P2P file sharing application from operating with G2 in hub mode; that will greatly reduce the number of inbound connections and thus you’ll see your U-Verse gateway operating much better.

There are, of course, advantages to operating in hub mode (and there needs to be nodes operating in hub mode for G2 to work efficiently); but with U-Verse you’re not doing the world any real good operating in a mode that slows traffic to a crawl.


While this post is relevant specifically to U-Verse, AT&T provides 2Wire gateways for ADSL service as well; so you may find that disabling hub mode in G2 on non-U-Verse systems improves overall performance as well.
