MTU = 1446

MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.

MSS = 1406

MSS is not optimized for broadband. Consider increasing your MTU value.

Default Receive Window (RWIN) = 1045440

RWIN Scaling (RFC1323) = 4 bits (scale factor of 8)

Unscaled Receive Window = 65340

For optimum performance, consider changing RWIN to a multiple of MSS.

Other values for RWIN that might work well with your current MTU/MSS:

517408 (MSS x 46 * scale factor of 8)

258704 (MSS x 46 * scale factor of 4)

129352 (MSS x 46 * scale factor of 2)

64676 (MSS x 46) 

bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 41817.6 kbps (5227.2 KBytes/s) @ 200ms

Your RcvWindow limits you to: 16727.04 kbps (2090.88 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = OFF

Time to live left = 56 hops

TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

This one has me confused. I tested the cablenut file I posted with my own connection and it will even support up to a 15 mbps/2 mb connection, at just over 14300 kbps. So there is definitely a hardwarde problem. When was the last time you reset your modem? if it's been a while you should do so and try testing again.

OK dumb question are you connected to your modem by ethernet cable or USB?  The way it's acting I'd almost think there is a 384/256 cap set on your connection. you might want to call your provider and have them check you modem's provisioning and  make sure it's set to what level you pay for.

Hold on. I think I may have figured out part of your problem, and it is something no amount of tweaking can fix. In your first post you stated that you used bittorrent to download. Now some ISP's have a limit as to how much you are allowed to download per month. if you reach this limit they cap your modem at a slower speed. I don't know your location so I can't look up the details of your SBC Yahoo DSL provider but i'm betting you were capped for downloading too much.

some isps cap you until you call to complain. then they connect you to their abuse department after the guy answering the phone sees the blinking red entry on your account. they read you the riot act, give you a final warning to cease and desist all activities etc. then uncap you. if you get caught again they kill your connection for good and blacklist you.
